LMS-S008-CR-LA-420Y/480T HSLA — Cold Rolled Steel

LMS-S008-CR-LA-420Y/480T is a hsla grade cold rolled steel conforming to the lucid material specifications. At 420 MPa minimum yield strength, this is high-strength steel for front-end structure components, rocker inners, and A-pillar reinforcements, with structural stamping capability for load-carrying components requiring consistent thickness reduction.

LMS-S008-CR-LA-420Y/480T is a Low Alloy / HSLA steel at 420 MPa yield and 480 MPa tensile. Micro-alloying elements in LMS-S008-CR-LA-420Y/480T — typically niobium, vanadium, or titanium — provide grain refinement and precipitation strengthening, delivering structural-grade mechanical properties with good weldability and formability for automotive and industrial applications.

Ameristeel carries LMS-S008-CR-LA-420Y/480T across a range of gauges and widths in cold rolled form, available as coils, sheets, or custom-cut blanks. With 420 MPa minimum yield strength, this hsla specification requires precise handling and testing — our ISO 9001:2015 certified processes include third-party laboratory verification on every incoming coil.

LMS-S008-CR-LA-420Y/480T 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 420 MPa yield, the coating selection for LMS-S008-CR-LA-420Y/480T should account for forming severity and post-stamping corrosion exposure in the final application.

LMS-S008-CR-LA-420Y/480T at 420 MPa yield and 480 MPa tensile compares to LMS-S008-HR-LA-420Y/480T (0 MPa lower yield at 420 MPa and 480 MPa vs 480 MPa tensile) and LMS-S008-CR-DP-440Y/780T (20 MPa lower yield at 440 MPa and 480 MPa vs 780 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
