GMW3032M-ST-S HR300LA HSLA Grade 40 — Hot Rolled Steel

GMW3032M-ST-S HR300LA is a hsla grade 40 grade hot rolled steel conforming to the gm material specifications. At 300 MPa minimum yield strength, this is intermediate-strength steel for structural cross-members, seat mounting brackets, and suspension component interfaces.

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 HR300LA 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 HR300LA include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

GMW3032M-ST-S HR300LA at 300 MPa yield compares to GMW3032M-ST-S CR300LA (0 MPa lower yield at 300 MPa) and GMW3399M-ST-S CR 490T/290Y-DP (10 MPa higher yield at 290 MPa). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
