LMS-S008-HR-FB-440Y/580T Ferritic Bainitic — Hot Rolled Steel

LMS-S008-HR-FB-440Y/580T is a ferritic bainitic grade hot rolled steel conforming to the lucid material specifications. At 440 MPa minimum yield strength, this is advanced-strength steel for B-pillar reinforcements, side impact beams, and roof bow structures, with substantial tensile reserve for energy-absorbing crush zones and progressive deformation members.

Ameristeel carries LMS-S008-HR-FB-440Y/580T across a range of gauges and widths in hot rolled form, available as coils, sheets, or custom-cut blanks. With 440 MPa minimum yield strength, this ferritic bainitic specification requires precise handling and testing — our ISO 9001:2015 certified processes include third-party laboratory verification on every incoming coil.

LMS-S008-HR-FB-440Y/580T 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 440 MPa yield, the coating selection for LMS-S008-HR-FB-440Y/580T should account for forming severity and post-stamping corrosion exposure in the final application.

LMS-S008-HR-FB-440Y/580T at 440 MPa yield and 580 MPa tensile compares to LMS-S008-CR-DP-440Y/780T (0 MPa lower yield at 440 MPa and 580 MPa vs 780 MPa tensile) and LMS-S008-CR-TR-450Y/780T (10 MPa lower yield at 450 MPa and 580 MPa vs 780 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
