LMS-S008-HR-LA-550Y/610T HSLA — Hot Rolled Steel

LMS-S008-HR-LA-550Y/610T is a hsla grade hot rolled steel conforming to the lucid material specifications. At 550 MPa minimum yield strength, this is ultra-high-strength steel for door intrusion beams, bumper reinforcements, and tunnel structures, with substantial tensile reserve for energy-absorbing crush zones and progressive deformation members.

LMS-S008-HR-LA-550Y/610T is a Low Alloy / HSLA steel at 550 MPa yield and 610 MPa tensile. Micro-alloying elements in LMS-S008-HR-LA-550Y/610T — 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 stocks LMS-S008-HR-LA-550Y/610T in production-ready gauges and widths suited to high-strength stamping applications. As a 550 MPa yield hot rolled product, this specification is available in coil, sheet, and precision-blanked formats. Our ISO 9001:2015 certified facility triple-tests every coil (ID, OD, and center) to verify mechanical properties remain consistent throughout the entire length.

LMS-S008-HR-LA-550Y/610T 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 550 MPa yield, the coating selection for LMS-S008-HR-LA-550Y/610T should account for forming severity and post-stamping corrosion exposure in the final application.

LMS-S008-HR-LA-550Y/610T at 550 MPa yield and 610 MPa tensile compares to LMS-S008-CR-DP-590Y/980T (40 MPa lower yield at 590 MPa and 610 MPa vs 980 MPa tensile) and LMS-S008-CR-TR-450Y/780T (100 MPa higher yield at 450 MPa and 610 MPa vs 780 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
