MS 50002-LAC 380Y-450T HSLA Grade 55 — Cold Rolled Steel

MS 50002-LAC 380Y-450T is a hsla grade 55 grade cold rolled steel conforming to the fiat/chrysler specifications. At 380 MPa minimum yield strength, this is high-strength steel for front-end structure components, rocker inners, and A-pillar reinforcements, with structural stamping capability for load-carrying components requiring consistent thickness reduction.

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 380Y-450T 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 380Y-450T 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 380Y-450T include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

MS 50002-LAC 380Y-450T at 380 MPa yield and 450 MPa tensile compares to MS 50002-LAH 380Y-450T (0 MPa lower yield at 380 MPa and 450 MPa vs 450 MPa tensile) and MS 50002-LAC 340Y-410T (40 MPa higher yield at 340 MPa and 450 MPa vs 410 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
