GMW3032M-ST-S CR380LA HSLA Grade 55 — Cold Rolled Steel

GMW3032M-ST-S CR380LA is a hsla grade 55 grade cold rolled steel conforming to the gm material specifications. At 380 MPa minimum yield strength, this is high-strength steel for front-end structure components, rocker inners, and A-pillar reinforcements.

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 CR380LA 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 CR380LA include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

GMW3032M-ST-S CR380LA at 380 MPa yield compares to GMW3032M-ST-S HR380LA (0 MPa lower yield at 380 MPa) and GMW3032M-ST-S CR340LA (40 MPa higher yield at 340 MPa). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
