RMS-1021 HR-460Y-520T-LA HSLA — Hot Rolled Steel

RMS-1021 HR-460Y-520T-LA is a hsla grade hot rolled steel conforming to the rivian material specifications. At 460 MPa minimum yield strength, this is advanced-strength steel for B-pillar reinforcements, side impact beams, and roof bow structures, with substantial tensile reserve for energy-absorbing crush zones and progressive deformation members.

As a Low Alloy / HSLA steel, RMS-1021 HR-460Y-520T-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-460Y-520T-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-460Y-520T-LA include Uncoated, Galvanized, Electrogalvanized, Galvannealed, Zinc-Magnesium-Aluminum, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

RMS-1021 HR-460Y-520T-LA at 460 MPa yield and 520 MPa tensile compares to RMS-1021 CR-460Y-520T-LA (0 MPa lower yield at 460 MPa and 520 MPa vs 520 MPa tensile) and RMS-1021 CR-450Y-780T-TR (10 MPa higher yield at 450 MPa and 520 MPa vs 780 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
