LMS-S008-CR-LA-340Y/410T HSLA — Cold Rolled Steel

LMS-S008-CR-LA-340Y/410T is a hsla grade cold rolled steel conforming to the lucid material specifications. At 340 MPa minimum yield strength, this is medium-strength structural steel for longitudinal rails, shotgun members, and frame reinforcement channels, with structural stamping capability for load-carrying components requiring consistent thickness reduction.

LMS-S008-CR-LA-340Y/410T is a Low Alloy / HSLA steel at 340 MPa yield and 410 MPa tensile. Micro-alloying elements in LMS-S008-CR-LA-340Y/410T — 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-340Y/410T across a range of gauges and widths in cold rolled form, available as coils, sheets, or custom-cut blanks. With 340 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-340Y/410T 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 340 MPa yield, the coating selection for LMS-S008-CR-LA-340Y/410T should account for forming severity and post-stamping corrosion exposure in the final application.

LMS-S008-CR-LA-340Y/410T at 340 MPa yield and 410 MPa tensile compares to LMS-S008-HR-LA-340Y/420T (0 MPa lower yield at 340 MPa and 410 MPa vs 420 MPa tensile) and LMS-S008-CR-DP-330Y/590T (10 MPa higher yield at 330 MPa and 410 MPa vs 590 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
