Definitions
- the invention relates to an austenitic high-manganese stainless steel having high strength and high ductility which stainless steel utilizes the TWIP (TWinning Induced Plasticity) mechanism during the deformation process.
- TWIP TWinning Induced Plasticity
- the austenitic stainless steels such as the most versatile and widely used 304 austenitic stainless steel, have a significantly lower strength combined with relatively high residual elongation after cold deformation, such as cold rolling.
- the ferritic austenitic duplex stainless steels such as the 2304 ferritic austenitic duplex stainless steel, offer a high strength, but loose ductility with even a low cold deformation degree.
- the austenitic manganese stainless steels with high carbon content are vulnerable to intergranular corrosion after welding in the weld and heat-affected zone due to chromium depletion in this area. Further, the typical manganese stainless steels are in general vulnerable to form martensitic phase after cold deformation, which could lead to delayed cracking.
- the FR patent application 2071 667 relates to an austenitic stainless steel which contains in weight % 0,02 - 0,3 % C, 0,1 - 3,0 % Si, 8,0 - 17,0 % Mn, 12,0 - 1 6,0 % Cr, 0,05 - 0,3 % N and optionally 0,1 - 3,0 % copper and 0,1 - 3,0 % Mo, the balance being formed of iron as essential ingredients in order to have austenitic phase after annealing.
- the object of the FR patent application 2071667 the object is to have improved softening and better forming properties.
- the US patent 6,454,879 describes a method for producing a forging piece of paramagnetic austenitic stainless steel containing in weight % up to 0,1 C, 0,21 - 0,60 Si, 20 - 30 % Mn, 17 - 24 % Cr, up to 2,5 % Ni, up to 1 ,9 % Mo, 0,6 - 1 ,4 % N up to 0,3 % Cu, up to 0,002 % B, up to 0,8 % carbide-forming elements, the balance including iron with the microstructure having substantially no ferrite content.
- Titanium, zirconium, vanadium and niobium are described as strong carbide and nitride and/or carbon nitride formers the contents of these elements being less than 0,8 weight %.
- the material is hot-formed at a temperature of at least 850 °C to a degree of deformation of at least about 3,5 times and actively cooled.
- the second step it is cold-formed in a deformation of 5 - 20 % below the deposit temperature of nitrides at elevated temperature below 600 °C, but greater than 350 °C.
- the deformation is in every process step thus carried out in elevated temperature which increases the manufacturing costs of the produced material.
- a twinning in the microstructure of a metal material is in general defined as two separate crystals that share some of the same crystal lattice.
- the TWIP (TWinning Induced Plasticity) stainless steels have austenitic microstructure with face-centered cubic lattice (FCC) along with a relatively low stacking fault energy (SFE) promoting the activation of twinning deformation mechanism, i.e. mechanically induced twinning in the crystal lattice.
- FCC face-centered cubic lattice
- SFE stacking fault energy
- TWIP indicates that twinning often goes along with accomodation plasticity via lattice dislocations.
- the object of the present invention is to eliminate some drawbacks of the prior art and to achieve an improved austenitic high-manganese stainless steel which utilizes the TWIP (TWinning Induced Plasticity) mechanism in the cold deformation in order to have a high work-hardening rate and good corrosion resistance with low vulnerability for intergranular corrosion after welding and for delayed cracking and stress corrosion cracking.
- TWIP TWinning Induced Plasticity
- the austenitic high-manganese stainless steel consists of in weight % 0,03 - 0,1 % carbon, 0,08 - 1 ,0 % silicon, 14 - 26 % manganese. 10,5 - 18 % chromium, less than 0,8 % nickel, 0,05 - 0,6 % copper, 0,1 - 0,8 % nitrogen and 0,0008 - 0,005 % boron, the rest being iron and inevitable impurities occurred in stainless steels.
- the austenitic stainless steel of the invention further contains optionally 0,001 - 0,02 % titanium and optionally less than 0,04 % aluminium.
- the austenitic stainless steel of the invention has a superior ductility and high strength after plastic deformation utilizing in the cold deformation the TWIP (TWinning Induced Plasticity) mechanism.
- the austenitic stainless steel of the invention combines thus a high strength in the initial annealed state and a high work hardening rate with a high elongation after the cold deformation, such as cold rolling, in connection with a low nickel content.
- the ranges for the yield strength R p0 ,2 and the tensile strength R m as well as the elongation to fracture A 80 at the annealed state the austenitic high-manganese stainless steel in accordance with the invention are 470 - 600 MPa for R p0 ,2, 800 - 930 MPa for R m and 40 - 60 % for A 80 after annealed at the temperature range of 1000 - 1 150 °C.
- the austenitic high-manganese stainless steel of the invention has a high work- hardening rate of at least 20 % with the deformation degree 10 % and at least 40 % with the deformation degree 20 % for the yield strength R p0 ,2. Further, the elongation to fracture A 8 o is 25 - 35 % with the deformation degree 10 % and 10 - 20 % with the deformation degree 20 % showing the good ductility.
- Carbon (C) is a valuable austenite forming and stabilizing element, which enables reduced use of expensive elements nickel and copper.
- the upper limit for carbon alloying (less than 0,1 %) is set by the risk of carbide precipitation, which deteriorates the corrosion resistance of the stainless steel.
- the carbon content is low enough to maintain good corrosion resistance.
- the reduction of the carbon content to low levels by the decarburization process is non- economical, and therefore, the carbon content shall not be less than 0,03 %.
- Silicon (Si) is added to stainless steels for deoxidizing purposes during melting and should not be below 0,08 %. Because silicon is a ferrite forming element, its content must be limited below 1 %.
- Manganese (Mn) is a key element of the austenitic stainless steel of the invention, ensuring the stable austenitic crystal structure and enabling the twinning mechanism and, further, the reduction of the use of more expensive nickel. Manganese also increases the solubility of nitrogen to the stainless steel. Plastic deformation accompanied with twinning deformation easily occurs in the case of an amount of manganese of 14 % or more without deformed structure, i.e. the strain-induced martensite.
- a high manganese content makes the decarburization process of the steel more difficult, impairs the surface quality and reduces the corrosion resistance of the steel. Therefore the manganese content shall be less than 26 %. Preferably, the manganese content is at the range of 17,5 - 26,0 %, more preferably at the range of 19 - 23 %. Chromium (Cr) is responsible of ensuring corrosion resistance of a stainless steel. Therefore, the chromium content in this stainless steel shall be at the minimum 10,5 %. Chromium is important in terms of avoiding the delayed cracking phenomenon. By increasing the content from this level the corrosion resistance of the steel can be improved.
- the chromium content shall be lower than 18 %. Chromium also increases the solubility of nitrogen.
- the chromium content is at the range of 12 - 1 6,0 %, more preferably at the range of 12,5 - 14 %.
- Nickel (Ni) is a strong austenite former and stabilizer, but nickel is an expensive element. However, very low nickel contents would necessitate impractically high alloying with the other austenite forming and stabilizing elements. Therefore, the nickel content shall be preferably lower than 0,8 % but preferably less than 0,5 %.
- Copper (Cu) is present as a residual of 0,05 - 0,6 %, preferably at the range 0,3 -0,6 %. Copper is a weak stabilizer of the austenite phase but, however, has a strong effect on the resistance to martensite formation. Copper also has a positive effect on ductility and forming properties.
- Nitrogen (N) is a strong austenite former and stabilizer. Therefore, nitrogen alloying improves the cost efficiency of the steel by enabling lower use of nickel and copper.
- nitrogen content shall be at least 0,1 %. High nitrogen contents increase the strength of the steel and thus make forming operations more difficult. Furthermore, risk of nitride precipitation increases with increasing nitrogen content. For these reasons, the nitrogen content shall not exceed 0,8 %, preferably the nitrogen content shall be lower than 0,6 %.
- Nitrogen increases the stacking fault energy (SFE), which is used for the prediction of the TW IP-effect, and thus enables for and facilitates the TW IP-effect.
- SFE stacking fault energy
- the austenitic stainless steel according to the invention does not form during cold rolling any deformation martensite at the room temperature or above. Therefore, the stainless steel of the invention has a high ductility.
- the austenitic stainless steel according to the invention is also free of stress corrosion cracking and delayed cracking, just even after aging process in air and also in 5 % sodium chloride (NaCI) environment.
- the austenitic stainless steel in accordance with invention was melted in the production scale and then cast into a slab form with the chemical composition in weight %
- the slabs were further hot rolled into the thickness of 4,0 mm and then annealed at the temperature 1080 °C.
- the austenitic stainless steel of the invention was further cold rolled with the rolling degree of 50 % to the thickness of 2,0 mm and annealed at the temperature 1080 °C.
- the annealed strip product was then tested by determining the yield strength R p0 ,2 and the tensile strength R m as well as the elongation to fracture A 80 .
- the stainless steel strip was cold deformed with the reduction degree of 10 % and then determined the yield strength R p o,2 and the tensile strength R m as well as the elongation to fracture A 8 o- The respective actions were also made for the cold deformed strip having the reduction degree of 20 %. The results for those test results are described in the following table: Reduction degree R p o,2 (MPa) Rm (MPa) A 80 (%)
- the austenitic stainless steel of the invention can be manufactured as slabs, blooms, billets and flat products such as coils, strips, plates, sheets, and long products such as bars, rods, wires, profiles and shapes, and tubular products such as pipes, tubes and can be applied for instance in automotive construction, in tanks, in crash relevant parts, in construction and in rail vehicles.
- the high-manganese austenitic stainless steel in accordance with the invention can be cold deformed in the state of as a strip annealed after hot working, such as hot rolling, as a strip annealed after cold working, such as cold rolling, or as a strip annealed after hot working and cold working and then cold deformed, such as cold rolled, in order to utilize the TWIP effect for higher yield and tensile strength values with still high ductility.
