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.

MS 50002-DPC 420Y-780T is classified as a Dual Phase steel at 420 MPa yield and 780 MPa tensile. MS 50002-DPC 420Y-780T at 420 MPa yield uses the dual-phase ferrite-martensite microstructure to deliver high work-hardening rates during forming, which translates to superior crash energy absorption in the finished component.

Ameristeel carries MS 50002-DPC 420Y-780T across a range of gauges and widths in cold rolled form, available as coils, sheets, or custom-cut blanks. With 420 MPa minimum yield strength, this dual phase specification requires precise handling and testing — our ISO 9001:2015 certified processes include third-party laboratory verification on every incoming coil.

MS 50002-DPC 420Y-780T is supplied with the following coating options: hot-dip galvanized (zinc) for general corrosion resistance; galvanneal (zinc-iron alloy) for superior paint adhesion and weldability; electrogalvanized for precise coating weight control and smooth surface finish. At 420 MPa yield, the coating selection for MS 50002-DPC 420Y-780T should account for forming severity and post-stamping corrosion exposure in the final application.

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.
