MS 50002-LAC 300Y-380T HSLA Grade 40 — Cold Rolled Steel

MS 50002-LAC 300Y-380T is a hsla grade 40 grade cold rolled steel conforming to the fiat/chrysler specifications. At 300 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 300Y-380T 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 300Y-380T 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 300Y-380T include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

MS 50002-LAC 300Y-380T at 300 MPa yield and 380 MPa tensile compares to MS 50002-LAH 300Y-370T (0 MPa lower yield at 300 MPa and 380 MPa vs 370 MPa tensile) and MS 50002-DPC 290Y-490T (10 MPa higher yield at 290 MPa and 380 MPa vs 490 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
