Hot rolled or cold rolled steel sheet with specified tensile strengths from 450 MPa to 1500 MPa, suitable for cold forming such as stamping, roll forming and tube making, and use in automotive applications.
- DP =Dual Phase (ferrite and martensite microstructure, including grades with low and high yield)
- FB = Ferrite-Bainite (ferrite and bainite microstructure)
- TR= TRIP “transformation induced plasticity” (ferrite, bainite and retained austenite microstructure)
- MP =Multi-Phase or Complex Phase (ferrite, martensite, bainite plus precipitation hardening)
- MS= Martensitic (mainly martensitic microstructure)
