RMS-1021 CR-590Y-980T-DP Dual Phase — Cold Rolled Steel

RMS-1021 CR-590Y-980T-DP is a dual phase grade cold rolled steel conforming to the rivian material specifications. At 590 MPa minimum yield strength, this is ultra-high-strength steel for door intrusion beams, bumper reinforcements, and tunnel structures, with very high tensile properties for peak structural performance in anti-intrusion and rollover protection members.

As a Dual Phase steel, RMS-1021 CR-590Y-980T-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-590Y-980T-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-590Y-980T-DP include Uncoated, Galvanized, Electrogalvanized, Galvannealed, Zinc-Magnesium-Aluminum, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

RMS-1021 CR-590Y-980T-DP at 590 MPa yield and 980 MPa tensile compares to RMS-1021 CR-600Y-980T-TR (10 MPa lower yield at 600 MPa and 980 MPa vs 980 MPa tensile) and RMS-1021 CR-550Y-650T-LA (40 MPa higher yield at 550 MPa and 980 MPa vs 650 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
