RMS-1021 HR-700Y-750T-LA HSLA — Hot Rolled Steel

RMS-1021 HR-700Y-750T-LA is a hsla grade hot rolled steel conforming to the rivian material specifications. At 700 MPa minimum yield strength, this is press-hardened-class steel for rollformed safety cage components and structural energy absorbers, with high tensile capacity for safety-critical crash path components requiring controlled collapse behavior.

As a Low Alloy / HSLA steel, RMS-1021 HR-700Y-750T-LA offers a specific combination of strength and formability engineered for advanced automotive manufacturing. This advanced high-strength classification meets demanding structural performance requirements.

Ameristeel maintains inventory of RMS-1021 HR-700Y-750T-LA 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 HR-700Y-750T-LA include Uncoated, Galvanized, Electrogalvanized, Galvannealed, Zinc-Magnesium-Aluminum, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

RMS-1021 HR-700Y-750T-LA at 700 MPa yield and 750 MPa tensile compares to RMS-1021 CR-700Y-980T-DP (0 MPa lower yield at 700 MPa and 750 MPa vs 980 MPa tensile) and RMS-1021 HR-660Y-780T-LA (40 MPa higher yield at 660 MPa and 750 MPa vs 780 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
