MS 50002-LAH 240Y-320T HSLA Grade 35 — Hot Rolled Steel

MS 50002-LAH 240Y-320T is a hsla grade 35 grade hot rolled steel conforming to the fiat/chrysler specifications. At 240 MPa minimum yield strength, this is structural-quality steel for inner body panels, dash panels, and trunk floor reinforcements, with moderate forming capability and balanced mechanical properties for semi-structural inner panels.

This specification uses the hot-rolled low-alloy (LAH) process route, offering cost-effective structural properties with wider gauge availability for underbody applications.

MS 50002-LAH 240Y-320T is a Low Alloy / HSLA steel at 240 MPa yield and 320 MPa tensile. Micro-alloying elements in MS 50002-LAH 240Y-320T — 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 MS 50002-LAH 240Y-320T in a range of thicknesses and widths for structural and forming applications. As a hot rolled product, this specification is supplied in coils, cut sheets, or blanked parts. Our dedicated purchasing team sources MS 50002-LAH 240Y-320T through direct mill relationships, and every incoming coil is third-party tested under our ISO 9001:2015 quality management system.

MS 50002-LAH 240Y-320T 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. At 240 MPa yield, the coating selection for MS 50002-LAH 240Y-320T should account for forming severity and post-stamping corrosion exposure in the final application.

MS 50002-LAH 240Y-320T at 240 MPa yield and 320 MPa tensile compares to MS 50002-LAC 240Y-320T (0 MPa lower yield at 240 MPa and 320 MPa vs 320 MPa tensile) and MS 50002-BHC 240Y-340T (0 MPa lower yield at 240 MPa and 320 MPa vs 340 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
