LMS-S008-CR-TR-450Y/780T TRIP — Cold Rolled Steel

LMS-S008-CR-TR-450Y/780T is a trip grade cold rolled steel conforming to the lucid material specifications. At 450 MPa minimum yield strength, this is advanced-strength steel for B-pillar reinforcements, side impact beams, and roof bow structures, with high tensile capacity for safety-critical crash path components requiring controlled collapse behavior.

LMS-S008-CR-TR-450Y/780T is a TRIP (Transformation-Induced Plasticity) steel at 450 MPa yield and 780 MPa tensile. The retained austenite in LMS-S008-CR-TR-450Y/780T transforms to martensite during deformation, providing exceptional uniform elongation and energy absorption capacity that make it suitable for complex safety-critical stampings.

Ameristeel carries LMS-S008-CR-TR-450Y/780T across a range of gauges and widths in cold rolled form, available as coils, sheets, or custom-cut blanks. With 450 MPa minimum yield strength, this trip specification requires precise handling and testing — our ISO 9001:2015 certified processes include third-party laboratory verification on every incoming coil.

LMS-S008-CR-TR-450Y/780T is supplied with the following coating options: hot-dip galvanized (zinc) for general corrosion resistance; galvanneal (zinc-iron alloy) for superior paint adhesion and weldability; electrogalvanized for precise coating weight control and smooth surface finish; zinc-magnesium for enhanced edge and cut-edge corrosion protection. At 450 MPa yield, the coating selection for LMS-S008-CR-TR-450Y/780T should account for forming severity and post-stamping corrosion exposure in the final application.

LMS-S008-CR-TR-450Y/780T at 450 MPa yield and 780 MPa tensile compares to LMS-S008-CR-DP-440Y/780T (10 MPa higher yield at 440 MPa and 780 MPa vs 780 MPa tensile) and LMS-S008-HR-FB-440Y/580T (10 MPa higher yield at 440 MPa and 780 MPa vs 580 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
