GMW3399M-ST-S HR580T/330Y-DP Dual Phase — Hot Rolled Steel

GMW3399M-ST-S HR580T/330Y-DP is a dual phase grade hot rolled steel conforming to the gm material specifications. At 330 MPa minimum yield strength, this is medium-strength structural steel for longitudinal rails, shotgun members, and frame reinforcement channels, with substantial tensile reserve for energy-absorbing crush zones and progressive deformation members.

This specification carries the dual-phase (DP) designation under GMW3399M with ferrite-martensite microstructure for energy absorption in crash structures.

As a Dual Phase steel, GMW3399M-ST-S HR580T/330Y-DP offers a specific combination of strength and formability engineered for advanced automotive manufacturing. The dual-phase microstructure of ferrite and martensite provides excellent work hardening and crash energy absorption.

Ameristeel maintains inventory of GMW3399M-ST-S HR580T/330Y-DP 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 GMW3399M-ST-S HR580T/330Y-DP include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

GMW3399M-ST-S HR580T/330Y-DP at 330 MPa yield and 580 MPa tensile compares to GMW3032M-ST-S CR340LA (10 MPa lower yield at 340 MPa) and GMW3032M-ST-S HR340LA (10 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.
