RMS-1021 CR-180Y-290T-BH Bake Hardenable — Cold Rolled Steel

RMS-1021 CR-180Y-290T-BH is a bake hardenable grade cold rolled steel conforming to the rivian material specifications. At 180 MPa minimum yield strength, this is formable mild steel suited for door inners, floor pans, and moderate-draw closure panels, with gentle forming loads and excellent surface finish retention for Class A exposed surfaces.

As a Bake Hardenable steel, RMS-1021 CR-180Y-290T-BH offers a specific combination of strength and formability engineered for advanced automotive manufacturing. Bake hardening increases yield strength during the paint-bake cycle, improving dent resistance in finished panels.

Ameristeel maintains inventory of RMS-1021 CR-180Y-290T-BH 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-180Y-290T-BH include Uncoated, Galvanized, Electrogalvanized, Galvannealed, Zinc-Magnesium-Aluminum, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

RMS-1021 CR-180Y-290T-BH at 180 MPa yield and 290 MPa tensile compares to RMS-1021 HR2-180Y-270T-M (0 MPa lower yield at 180 MPa and 290 MPa vs 270 MPa tensile) and RMS-1021 HR3-180Y-270T-M (0 MPa lower yield at 180 MPa and 290 MPa vs 270 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
