MS 50002-LAH 380Y-450T HSLA 55 — Hot Rolled Steel

MS 50002-LAH 380Y-450T is a hsla 55 grade hot 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 hot-rolled low-alloy (LAH) process route, offering cost-effective structural properties with wider gauge availability for underbody applications.

As a Low Alloy / HSLA steel, MS 50002-LAH 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-LAH 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-LAH 380Y-450T include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

MS 50002-LAH 380Y-450T at 380 MPa yield and 450 MPa tensile compares to MS 50002-LAC 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.
