Definitions
- the present invention relates to a red scale resistance used for engine exhaust gas passage members (for example, mufflers, 'catalyst carriers, exhaust pipes, etc.) of motorcycles.
- the present invention relates to an excellent aluminum-based steel sheet, and a motorcycle exhaust gas passage member using the same.
- Conventional technology The exhaust gas path of motorcycles is shorter than that of automobiles, and it is not uncommon for downstream members such as mufflers to be exposed to temperatures of 400 ° C or higher.
- exhaust gas regulations have been tightened, and exhaust gas purification devices using a three-way catalyst are being installed in motorcycles. However, in the case of two-wheeled vehicles, such purification devices are often installed in mufflers.
- heat-resistant ferritic stainless steels such as S UH 4 009 L and S U S 4 3 6 are used for exhaust gas passage members of motorcycles.
- red scale In exhaust gas path members using stainless steel, a reddish brown scale (hereinafter referred to as “red scale”) may occur. This is a phenomenon that tends to occur in an exhaust gas temperature of 400 to 700 ° C. and in a low oxygen and high water vapor atmosphere. When a red scale develops and mixes with condensed water, it becomes a reddish brown liquid. Condensed water in the exhaust gas path may be discharged from the exhaust port together with the exhaust gas, but the discharge of the reddish brown liquid as described above is very undesirable in appearance.
- the muffler in the exhaust gas passage member is a portion where condensed water tends to accumulate.
- the muffler In the case of a typical four-wheeled vehicle, the muffler is rarely exposed to exhaust gas of 400 ° C or higher, and corrosive due to condensed water condensing inside rather than the red scale generated inside the muffler. Is likely to be a problem.
- the muffler is often exposed to 400 ° C or higher as described above, so red scale is generated in the muffler, and the discharge of reddish brown liquid due to the red scale tends to be a problem.
- Patent Document 1 discloses a technique for suppressing the generation of red scale in a stove combustion cylinder or the like by generating an oxide film mainly composed of a Cr-based oxide on the surface in advance.
- the oxide film is inferior in corrosion resistance, it is necessary to take measures to improve the corrosion resistance of the steel substrate, leading to an increase in material costs. For this reason, it is difficult to apply to exhaust gas passage members.
- Patent Documents 2 and 3 disclose methods for improving the red scale by using a steel containing a large amount of A 1 Si.
- the formability of such high-A and Si-added steels is better than that of SUH2 1 (a steel type with a good scale resistance of the 18 C r— 3 A 1 system). It is considerably inferior to ferritic stainless steel grades such as SUS 4 10 L and SUS 430 LX. For this reason, it is not suitable for exhaust gas passage members of motorcycles.

- Patent Document 1 3 Japanese Patent Laid-Open No. 8-3 2 5 6 9 1 Problem to be Solved by the Invention According to the inventors' investigation, the resistance to red scale generation of Cr-containing steel plates such as stainless steel (hereinafter referred to as “red scale”) In order to improve “red scale resistance”), it is effective to apply the A1 series. However, when the inventors investigated in detail the above-mentioned known A1-based steel plates, it was found that these have problems to be improved in widespread practical use as motorcycle exhaust gas passage members. .
- the A1 series plated steel sheet of Patent Document 4 is obtained by concentrating the alloy layer with Mn and the like, and it cannot be said that the thickness of the masked layer is sufficiently thin. It was judged that the peel-off resistance of the melt-adhered coating layer including the alloy layer was called “plating coating layer” was insufficient. Since the plated steel sheets of Patent Documents 5 and 6 have a large plating layer thickness, they also have insufficient peel resistance.
- the steel plates of Patent Documents 7, 8, and 10 can be obtained by applying Ni-based pre-plating followed by A1-based plating. Therefore, it cannot be easily adopted for exhaust gas passage members such as mufflers and catalyst carriers that are strongly required to reduce costs.
- the plated steel sheet of Patent Document 9 prevents abnormal oxidation at a high temperature of 1 1550 to 1250 ° C by using a steel in which a rare earth element or Y is essential as a base material. However, it is easy to peel off the clinging coating layer after repeated heating and cooling to the 400-700 ° C region. Since the plated steel sheets of Patent Documents 1 and 1 and 2 are not sufficiently thin, the plating coating layer has poor peeling resistance to heating and cooling in the range of 400 to 700 ° C. It is enough.
- “Akaban” described in Patent Document 11 is typically found in ordinary steel that has been corroded at room temperature. It is a red coral and is different from the “red scale” in this application.
- the known A1-based stainless steel sheet cannot be said to have sufficient peeling resistance of the plating coating layer when heated to a temperature range of 4 ° C. to 700 ° C. basically. Therefore, the conventional A1-type stainless steel plate is suitable for motorcycle mufflers and catalyst carriers used in the temperature range of 400 to 700 ° C. Even if it exhibits the properties, the clinging layer peels off during long-term use, and if the corrosion resistance is reduced, the red scale resistance is reduced. In other words, it has an anxiety factor in terms of durability.
- steel plates for exhaust gas members are also required to have good formability and low temperature toughness. Low cost is also important for practical application.
- the present invention is an A1-based steel plate for use in a motorcycle exhaust gas passage member, and has excellent red scale resistance, formability, and low temperature toughness, and is repeated in a temperature range of 400 to 700 ° C. It is an object to provide an inexpensive A1-based steel sheet that can remarkably improve the peel resistance of the plating coating layer when heated. Means for Solving the Problems As a result of detailed investigations, the inventors have made the A 1 system adhesive coating layer remarkably resistant to peeling by controlling the thickness of the A 1 system adhesive layer to 20 ⁇ or less. As a result, the present invention has been completed.
- the composition of the steel substrate is, by mass%, C: 0.02% or less, S i: 1% or less, Mn: 1% or less, C r: 5 to 25%, T i: 0.3% or less, N: 0.02% or less, and if necessary, Ni: 0.6% or less, Nb: 0.1% or less, A1: 0.2% or less, Mo: 3% Cu: 3% or less, W: 3% or less, V: 0.5% or less, Co: 0.5% or less, B: 0.01% or less, the balance being Fe and A steel plate that is an inevitable impurity And
- the base material contains, in mass%, Si: 3 to 12%, and in some cases, one or more of Ti, B, Sr, Cr, Mg, and Zr may be 1% or less in total. In the range of 3 to 20 ⁇ ⁇ , an average thickness of 3 to 20 ⁇ is obtained by dipping in a molten simmering bath consisting of the balance A 1 and inevitable impurities and then lifting and adjusting the amount of plating.
- a 1-type steel plate for motorcycle exhaust gas passage parts with excellent red scale resistance formed on the surface is provided.
- a two-wheeled vehicle exhaust gas passage member having a structure in which the plated steel plate is used as a raw material and having a structure in which the adhesion layer is in contact with exhaust gas and having a maximum use temperature of 400 ° C. or more.
- the A1-based steel sheet of the present invention is excellent in red scale resistance and exfoliation resistance of the coating layer when repeatedly heated in the temperature range of 400 to 700 ° C. It is suitable for an exhaust gas passage member (for example, a muffler member) of a two-wheeled vehicle used in an environment that is heated in the temperature range and easily generates red scale.
- the manufacturing cost can be kept to the same level or lower than that of a typical A1-plated stainless steel sheet. Therefore, the present invention can contribute to improving the quality and durability of the exhaust gas passage member of a motorcycle.
- high Cr steel such as ferritic stainless steel is heated to a high temperature
- an oxide having a high Cr concentration (Cr based oxide) is generally formed on the surface of the steel base. Since this Cr-based oxide is highly protective, high Cr steels generally have better high temperature oxidation resistance than low Cr steels. However, even with such high Cr steel, when it is heated in a temperature range of 400 to 700 ° C and in a low oxygen and high water vapor atmosphere, the Cr-based steel is used in the initial oxidation process.
- Fe-based oxides are more easily produced than oxides. This is because, in this temperature range, Cr that is sufficient to cover the surface of the steel substrate with Cr-based oxides cannot be rapidly diffused on the surface. Under high water vapor atmosphere Is preferentially oxidized.
- the red scale is composed of Fe oxides generated on the surface as described above.
- the A1-based cover layer is likely to peel off from the surface of the steel substrate after repeated heating and cooling to a temperature of 400 to 700 ° C. all right. This is a major factor that does not necessarily show good durability when the conventional A1 steel plate is used for a muffler member of a motorcycle.
- the Fe-A1-based intermetallic compound layer is formed by the mutual diffusion of A1 in the plating layer and Fe in the steel substrate. , And separation occurs between the intermetallic compound layer and the steel substrate.
- the plating coating layer is peeled off in this way, a new red scale is generated from there.
- the inventors have studied in detail the technique for preventing the peeling of the plating coating layer of the A1-based steel sheet. As a result, it is possible to reduce the thickness of the A 1 system plating layer in the temperature range of 400 to 700 ° C. and when heated in a low oxygen high water vapor atmosphere. It was found to be extremely effective in suppressing the peeling phenomenon. In this case, it is not necessary to place special regulations on the chemical composition of the base steel sheet, the composition of the A 1-based plating layer, the structural state, or the alloy layer composition.
- the average thickness of the A1-based plating layer is a thickness not including the alloy layer.
- the adhesion amount by fusion can be adjusted by the gas wiping method, etc.
- the plating adhesion amount per side is controlled to be 20 ⁇ or less, part of it will react with the steel substrate. Formed as an alloy layer.
- the average thickness of the 1-layered layer does not exceed 20 ⁇ . If the operating conditions are such that the alloy layer is formed to be relatively thick, the average thickness of the plating layer can be reduced even if the plating adhesion amount is set to be slightly thicker than 20 ⁇ .
- the peel resistance is further improved. Accordingly, those in which the average thickness of the A 1-based plating layer per side is less than 15 ⁇ are particularly preferred targets in the present invention.
- the alloy layer is brittle compared to the steel substrate and the staking layer. For this reason, the thickness of the alloy layer is preferably thinner in consideration of workability. There is no need to pay particular attention to the use of parts with a low degree of processing. However, when severe processing is performed, the average thickness of the alloy layer per one side is preferably 5 ⁇ or less, more preferably 4 ⁇ or less. . It is fully possible to manufacture such a thin alloy layer thickness in the melted A1-based mating line using the gas wiping method. When the total thickness of the plating layer thickness and the alloy layer thickness is viewed, the alloy so that the “average thickness of the A1 plating layer + average thickness of the alloy layer” per side is less than 24 ⁇ . It is desirable to control the layer thickness.
- the liquidus temperature decreases, and the eutectic composition is obtained around 12 mass% 3 i.
- a molten A1-based bath containing 3% by mass or more of Si is used. If the composition is richer than A 1, the bath temperature will increase, so the average thickness of the alloy layer will be reduced.
- the present invention is directed to a steel plate manufactured using a molten A1-based bath containing 3 to 12% by mass of Si.
- one or more of Ti, B, Sr, Cr, Mg, and Zr may be contained within a total range of 1% or less.
- Fe is included as an inevitable impurity in the bath, but mixing of Fe is allowed within a range of 2.5% by mass or less.
- the base steel plate used as the plating base plate is a high Cr steel containing 5 to 25% by mass of Cr. Since the corrosion resistance and oxidation resistance are improved by applying the A1 system, the Cr content at the stainless steel level is not necessarily required, but the exhaust from motorcycles exposed to an environment in contact with condensed water or water vapor is not necessarily required. In order to ensure the corrosion resistance required as a gas path member and to ensure red scale resistance, a Cr content of at least 5 mass% is required. It is more preferable to secure a Cr content of 10% by mass or more. Corrosion resistance and heat resistance improve as the Cr content increases, but excessive Cr content is uneconomical and also becomes a factor that hinders formability and low temperature toughness. The amount is specified in the range of 25% by mass or less.
- Ti is an effective element for fixing C and N in steel, stabilizing the ferrite phase, and improving low temperature toughness and formability.
- it is preferable to secure a Ti content of 0.05% by mass or more, and more preferably, 0.1% by mass or more.
- a Ti content is limited to a range of 0.3% by mass or less, and it is more preferable to add in a range of 0.2% by mass or less.
- C, Si, Mn, and N are basic elements contained in the steel, and their contents are C: 0.02% or less, Si: 1% or less, Mn: 1% or less, N: 0.00. It can be within the range of 02% or less.
- Other elements include Ni: ⁇ .6% or less, Nb: 0.1% or less, A1: 0.2% or less, Mo: 3% or less, Cu: 3% or less, W: 3% or less , V: 0.5% or less, Co: 0.5. /.
- B One or more elements may be contained in an amount of not more than 0.01%. However, if the content of these elements exceeds the above specifications, the moldability and the low temperature toughness may be adversely affected.
- the inevitable impurity P is allowed up to about 0.04 mass%, and S is allowed up to about 0.03 mass%.
- the base steel sheet can be manufactured by a general steel sheet manufacturing process, and the manufacturing method is not particularly specified.
- a cold-rolled steel sheet with a pickled finish can be used as the base material, and the surface of the base steel sheet is activated and then dipped in a molten A1-based bath to adjust the amount of plating.
- the molten A1-based steel sheet of the present invention can be manufactured.
- a steel plate that has been Fe pre-plated to improve plating properties can be used as the base steel sheet.
- the obtained plated steel sheet is processed into an exhaust gas path member for a motorcycle through a predetermined forming process. Depending on the member, it is formed into a welded pipe and then processed.
- Ferritic steel types having the compositions shown in Table 1 were melted, and a cold-rolled annealed steel sheet (pickled finish) having a thickness of 1.2 mm was obtained by a conventional method. All steel types are inevitable impurities, P is 0.04 mass% or less, and S is 0.01 mass% or less. These steel plates were used as the base material (plating base plate), and various melted A 1-type plating was applied. For Nos. 19 and 29, the surface of the cold-rolled annealed steel sheet subjected to Fe pre-plating (2 g / m 2 ) was used as the base material. In addition, about 1.7% by mass of Fe is included in the plating baths of all the examples as an inevitable impurity.
- Each test material was evaluated for red scale resistance, peel resistance of the plating coating layer, formability, and low temperature toughness as follows.
- Cycle heating “Heating in a nitrogen atmosphere with a dew point of 80 ° C for 30 minutes at 600 ° C (of which soaking time is 25 minutes) ⁇ air cooling for 5 minutes” is one cycle and this is repeated 500 cycles.
- Nos. 51 and 54 as comparative examples were inferior in red scale resistance to the fact that the average thickness of the A1-based adhesive layer was too thin.
- Nos. 52, 53, 55, 56, and 57 were inferior in the peel resistance of the plating coating layer because the average thickness of the A1-based layer exceeded 20 ⁇ .
- ⁇ .57 was inferior in low-temperature toughness due to the excessive Ti content of the base steel sheet.
- No. 58 was inferior in formability and low-temperature toughness due to the Cr content of the base steel plate and No. 59 being too high in the Mo content of the base steel plate.
- No. 60 was inferior in low temperature toughness due to too much Si and Mn content in the base steel sheet.
- No. 61 was inferior in red scale resistance due to the Cr content of the base steel sheet being too small.
- N 0.62 was inferior in formability and low temperature toughness due to the excessive Cu content in the base steel sheet.
