Definitions
- the invention relates to the use of a lightweight steel.
- the invention has for its object a good cold-formable, especially deep-drawable, Lightweight steel with a tensile strength up to 1100 MPa and with TRIP and TWIP properties, the one with alloyed inexpensive elements and therefore inexpensive is producible and for the production of highly stressed sheet metal parts is usable.
- This object is achieved according to the invention through the use of a cold-formable, in particular deep-drawable, austenitic lightweight steel, which has a tensile strength up to 1100 MPa and TRIPund TWIP properties, with (in mass%) 1 to 6% Si, 1 to 8% Al, wherein (Al + Si) ⁇ 12%, 10 to 30% Mn, balance essentially iron including conventional ones Steel accompanying elements as material for body sheet metal parts and stiffening Body elements made of sheet metal.
- the steel mentioned can also be used as a material for hot and / or cold-rolled sheets for containers used in the low temperature range and / or Pipelines are used.
- the lightweight steel used according to the invention preferably contains 2 to 4% Si and Al and 24 to 26% Mn, balance essentially iron.
- the steels used are characterized by higher yield stresses from 400 MPa due to the high solidification rate Have tensile strength values up to 1100 MPa and Uniform stretch values up to 70% and maximum strains achieve up to 90%.
- the high values of energy absorption - dissipative energy - of 0.5 J.mm -3 are based on the deformation-induced martensitic phase transformation and the intensive formation of twins in the austenite phase. These and the mechanical properties are retained even at extremely high forming speeds of up to 10 3 s -1 .
- the excellent plasticity of the TRIP and TWIP steels used according to the invention is retained down to low temperatures.
- the steel used according to the invention achieves a density which is reduced to 7 g / cm 3 due to the alloying elements Al, Si and Mn.
