RMS-1021 CR-290Y-490T-DP Dual Phase — Cold Rolled Steel

RMS-1021 CR-290Y-490T-DP is a dual phase grade cold rolled steel conforming to the rivian material specifications. At 290 MPa minimum yield strength, this is intermediate-strength steel for structural cross-members, seat mounting brackets, and suspension component interfaces, with structural stamping capability for load-carrying components requiring consistent thickness reduction.

As a Dual Phase steel, RMS-1021 CR-290Y-490T-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 CR-290Y-490T-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 CR-290Y-490T-DP include Uncoated, Galvanized, Electrogalvanized, Galvannealed, Zinc-Magnesium-Aluminum, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

RMS-1021 CR-290Y-490T-DP at 290 MPa yield and 490 MPa tensile compares to RMS-1021 CR-300Y-390T-BH (10 MPa lower yield at 300 MPa and 490 MPa vs 390 MPa tensile) and RMS-1021 CR-330Y-590T-DP (40 MPa lower yield at 330 MPa and 490 MPa vs 590 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
