GMW3032M-ST-S HR340LA HSLA Grade 50 — Hot Rolled Steel

GMW3032M-ST-S HR340LA is a hsla grade 50 grade hot rolled steel conforming to the gm material specifications. At 340 MPa minimum yield strength, this is medium-strength structural steel for longitudinal rails, shotgun members, and frame reinforcement channels.

This specification carries the low-alloy (LA) designation under GMW3032M with micro-alloyed composition for structural strength with good weldability.

Ameristeel maintains inventory of GMW3032M-ST-S HR340LA in various gauges and widths, available as coils, sheets, or custom blanks. Our ISO 9001:2015 certified processes ensure consistent quality from prototype through production volumes.

Available coating options for GMW3032M-ST-S HR340LA include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

GMW3032M-ST-S HR340LA at 340 MPa yield compares to GMW3032M-ST-S CR340LA (0 MPa lower yield at 340 MPa) and GMW3399M-ST-S CR 590T/340Y-DP (0 MPa lower yield at 340 MPa). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
