RMS-1021 HR-330Y-580T-DP Dual Phase — Hot Rolled Steel

RMS-1021 HR-330Y-580T-DP is a dual phase grade hot rolled steel conforming to the rivian 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.

As a Dual Phase steel, RMS-1021 HR-330Y-580T-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 RMS-1021 HR-330Y-580T-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 RMS-1021 HR-330Y-580T-DP include Uncoated, Galvanized, Electrogalvanized, Galvannealed, Zinc-Magnesium-Aluminum, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

RMS-1021 HR-330Y-580T-DP at 330 MPa yield and 580 MPa tensile compares to RMS-1021 CR-330Y-590T-DP (0 MPa lower yield at 330 MPa and 580 MPa vs 590 MPa tensile) and RMS-1021 CR-340Y-410T-LA (10 MPa lower yield at 340 MPa and 580 MPa vs 410 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
