Definitions
- the invention relates to a high-strength steel strip or sheet with a predominantly ferritic-martensitic Structure and a process for its production.
- a well-formable steel band or sheet stands out due to high r-values, which stand for good deep drawability, high n-values for good stretchability and high, positive plane-strain properties indicating elongation values. Also characteristic of good stretchability is low Yield strength ratio, which is the quotient of Yield strength and tensile strength is formed.
- DE 30 07 560 A describes a method for Manufacture of essentially ferrite and Known martensite existing hot-rolled sheet. The aim is to use a sheet steel with a lower one Yield strength, high tensile strength and excellent Deformability.
- the object of the invention is a one High-strength steel strip made of dual-phase steel to create or sheet, which also after passage an annealing process including one Aging treatment good mechanical-technological Possesses properties. It is also intended to be a procedure for the production of such a strip or sheet can be specified.
- a steel strip or sheet steel according to the invention has high strengths of at least 500 N / mm 2 with good formability at the same time, without the need for particularly high contents of certain alloying elements.
- the invention makes use of the conversion-influencing effect of the element boron, which is already known per se in steels for hot-rolled strips and forgings.
- the strength-increasing effect of boron is ensured by adding at least one alternative nitride former, preferably Al and additionally Ti, to the steel material according to the invention.
- the effect of the addition of titanium and aluminum is that they bind the nitrogen contained in the steel, so that boron is available for the formation of hardness-increasing carbides. Supported by the necessary Cr content, a higher level of strength is achieved in this way than with comparable steels, which are composed in a conventional manner.
- the yield strengths of a strip or sheet according to the invention are between 250 N / mm 2 and 350 N / mm 2 .
- the tensile strengths are 500 N / mm 2 to more than 600 N / mm 2 , in particular up to 650 N / mm 2 .
- a steel strip or sheet according to the invention thus has properties and features that could not previously be achieved for low-alloy steels.
- steels according to the invention are their resistance to tempering effects. That in particular with conventionally composed two-phase steels existing problem that the martensite share in a Aging treatment is left on and on it Way to a decrease in strength comes at steels according to the invention composed by the Avoid presence of chrome.
- the Al content can be limited to a range of 0.02-0.05 mass%.
- the nitrogen contained in the steel is not only offered as Al as a nitride former, but there is also a sufficient amount of Ti for the stoichiometric setting of the nitrogen. If, on the other hand, there is no Ti in the steel, the Al content of the steel strip or sheet should be from 0.1 to 0.4% by mass. The presence of aluminum and / or titanium initially results in the formation of relatively coarse-grained TiN and / or AlN.
- One way of producing an inventive Steel strip or sheet consists of the steel strip or sheet by cold rolling a hot strip produce.
- a thin hot strip can also be used without further cold rolling to an inventive Steel strip can be processed, provided its thickness for the Further processing is sufficiently reduced.
- Such one Hot strip can, for example, on a casting and rolling line are produced in which a cast steel strand immediately rolled into a hot strip of small thickness becomes.
- the above task with regard to Manufacturing process solved in that the steel strip or - subjected to an annealing treatment in the continuous furnace at which the annealing temperature is between 750 ° C and 870 ° C, preferably between 750 ° C and 850 ° C, and that the annealed steel strip or sheet is then from the annealing temperature with a cooling rate of cooled at least 20 ° C / s and at most 100 ° C / s becomes.
- the method according to the invention can be based on a C-Mn steel, the boron and at least Al and possibly in addition, Ti is added as a nitride former Manufacture steel band, which also under the specified Annealing and cooling conditions the desired high Has a martensite content of around 5% to 20%.
- a nitride former Manufacture steel band which also under the specified Annealing and cooling conditions the desired high Has a martensite content of around 5% to 20%.
- the boron freely dissolved in the lattice ensures that the formation of martensite even at low Cooling rates set in such a way that a predominant ferrite / martensite structure with the dual-phase characteristic combinations are created.
- Table 1 shows the alloy contents and the technological-mechanical parameters A RE (yield strength), R eL (lower yield strength), R m (tensile strength), R eL / R m (yield strength ratio ) and A 80 (elongation at break) for steel strips A1 according to the invention. A4 specified. In the same table, the corresponding information on comparative steel strips B1 - B5, C1 - C5, D1 - D4 and E1 are compared.
- Comparative steel strips B1 - B5 are the Mn content of 1.5 - 2.4 mass% to influence the Conversion behavior has been used.
- Comparative steel strips C1 - C5 is one for the same purpose Element combinations of Si (around 0.4 mass%) and Mn (1.5 - 2.4 mass%) and in the case of the comparative steel strips D1 - D4 a combination of the Si contents (up to 0.7 Mass%), Mn (1.2 - 1.6 mass%) and Cr (0.5 mass%) been used.
- the comparison steel strip is E1 additional Mo provided.
- the respective cold-rolled steel strip became one Continuous annealing, which takes place at a Standard procedure with aging for low-alloy, oriented towards soft steels.
- Essential characteristics of this Glow and aging treatments were one Annealing temperature during continuous annealing of 800 ° C and a two-part cooling with final Pass through the aging zone. The cooling took place initially to 550 - 600 ° C with a cooling rate of approx. 20 ° C / s. Then with one Cooling rate from approx. 50 ° C / s to 400 ° C cooled.
- the final aging treatment consisted of holding in the temperature range of 400-300 ° C for 150 s.
- the mechanical-technological characteristic values given in Table 1 for the steel strips A1 to A4 produced according to the invention after conventional continuous annealing in the undressed state demonstrate the advantageous properties of the steel strips or sheets produced according to the invention in comparison with the additionally stated high-strength alloy concepts of the comparative steel strips.
- the absence of an elongation limit in the undressed state in the steel strips according to the invention clearly indicates the favorable ferrite / martensite structure.
- the yield strengths are below 300 N / mm 2 and the strength values between 530 N / mm 2 and 630 N / mm 2 .
- the respective steel strip A1 - A4 exhibits good hardening behavior in the case of plastic deformation, which is also manifested in a very low yield strength ratio (R e / R m ⁇ 0.5).
- the elongation at break values for strengths of 540 - 580 N / mm 2 are between 27 and 30%; for approx. 630 N / mm 2 with a still good 25%.
- the overall mechanical properties are isotropic.
