RMS-1021 HR2-180Y-270T-M Mild Steel — Hot Rolled Steel

RMS-1021 HR2-180Y-270T-M is a mild steel grade hot 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.

The Class 2 designation indicates drawing quality for moderate forming operations. Within the RMS family, different class numbers reflect progressively different ductility and elongation requirements to suit varying stamping complexity.

Ameristeel maintains inventory of RMS-1021 HR2-180Y-270T-M 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 HR2-180Y-270T-M include Uncoated, Galvanized, Electrogalvanized, Galvannealed, Zinc-Magnesium-Aluminum, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

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