RMS-1021 CR-900Y-1180T-DP Dual Phase — Cold Rolled Steel

RMS-1021 CR-900Y-1180T-DP is a dual phase grade cold rolled steel conforming to the rivian material specifications. At 900 MPa minimum yield strength, this is hot-stamped-equivalent steel for critical occupant protection zones and maximum intrusion resistance, with extreme tensile strength for maximum occupant protection performance in the most severe crash scenarios.

As a Dual Phase steel, RMS-1021 CR-900Y-1180T-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-900Y-1180T-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-900Y-1180T-DP include Uncoated, Galvanized, Electrogalvanized, Galvannealed, Zinc-Magnesium-Aluminum, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

RMS-1021 CR-900Y-1180T-DP at 900 MPa yield and 1180 MPa tensile compares to RMS-1021 CR-850Y-1180T-TR (50 MPa higher yield at 850 MPa and 1180 MPa vs 1180 MPa tensile) and RMS-1021 CR-1050Y-1300T-MS (150 MPa lower yield at 1050 MPa and 1180 MPa vs 1300 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
