MS 50002-DPC 420Y-780T Dual Phase — Cold Rolled Steel

MS 50002-DPC 420Y-780T is a dual phase grade cold rolled steel conforming to the fiat/chrysler specifications. At 420 MPa minimum yield strength, this is high-strength steel for front-end structure components, rocker inners, and A-pillar reinforcements, with high tensile capacity for safety-critical crash path components requiring controlled collapse behavior.

This specification uses the cold-rolled dual-phase (DPC) process route with controlled cooling to develop the ferrite-martensite microstructure for crash energy management.

As a Dual Phase steel, MS 50002-DPC 420Y-780T offers a specific combination of strength and formability engineered for advanced automotive manufacturing. The dual-phase microstructure of ferrite and martensite provides excellent work hardening and crash energy absorption.

Ameristeel maintains inventory of MS 50002-DPC 420Y-780T 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-DPC 420Y-780T include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

MS 50002-DPC 420Y-780T at 420 MPa yield and 780 MPa tensile compares to MS 50002-LAC 420Y-480T (0 MPa lower yield at 420 MPa and 780 MPa vs 480 MPa tensile) and MS 50002-LAH 420Y-480T (0 MPa lower yield at 420 MPa and 780 MPa vs 480 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
