RMS-1021 HR-340Y-410T-LA HSLA — Hot Rolled Steel

RMS-1021 HR-340Y-410T-LA is a hsla grade hot rolled steel conforming to the rivian material specifications. At 340 MPa minimum yield strength, this is medium-strength structural steel for longitudinal rails, shotgun members, and frame reinforcement channels, with structural stamping capability for load-carrying components requiring consistent thickness reduction.

As a Low Alloy / HSLA steel, RMS-1021 HR-340Y-410T-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-340Y-410T-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-340Y-410T-LA include Uncoated, Galvanized, Electrogalvanized, Galvannealed, Zinc-Magnesium-Aluminum, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

RMS-1021 HR-340Y-410T-LA at 340 MPa yield and 410 MPa tensile compares to RMS-1021 CR-340Y-410T-LA (0 MPa lower yield at 340 MPa and 410 MPa vs 410 MPa tensile) and RMS-1021 CR-330Y-590T-DP (10 MPa higher yield at 330 MPa and 410 MPa vs 590 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
