MS 50002-LAC 270Y-340T HSLA Grade 40 — Cold Rolled Steel

MS 50002-LAC 270Y-340T is a hsla grade 40 grade cold rolled steel conforming to the fiat/chrysler specifications. At 270 MPa minimum yield strength, this is intermediate-strength steel for structural cross-members, seat mounting brackets, and suspension component interfaces, with moderate forming capability and balanced mechanical properties for semi-structural inner panels.

This specification uses the cold-rolled low-alloy (LAC) process route, providing tight thickness tolerances and controlled surface roughness for precision stamping.

As a Low Alloy / HSLA steel, MS 50002-LAC 270Y-340T 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 MS 50002-LAC 270Y-340T 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 MS 50002-LAC 270Y-340T include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

MS 50002-LAC 270Y-340T at 270 MPa yield and 340 MPa tensile compares to MS 50002-LAH 270Y-330T (0 MPa lower yield at 270 MPa and 340 MPa vs 330 MPa tensile) and MS 50002-IFC 280Y-380T (10 MPa lower yield at 280 MPa and 340 MPa vs 380 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
