MS 50002-DPC 550Y-980T Dual Phase — Cold Rolled Steel

MS 50002-DPC 550Y-980T is a dual phase grade cold rolled steel conforming to the fiat/chrysler specifications. At 550 MPa minimum yield strength, this is ultra-high-strength steel for door intrusion beams, bumper reinforcements, and tunnel structures, with very high tensile properties for peak structural performance in anti-intrusion and rollover protection members.

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 550Y-980T is classified as a Dual Phase steel at 550 MPa yield and 980 MPa tensile. With 550 MPa yield and 980 MPa tensile, MS 50002-DPC 550Y-980T targets high-energy crash structures where controlled deformation and energy absorption are critical design parameters.

Ameristeel stocks MS 50002-DPC 550Y-980T in production-ready gauges and widths suited to high-strength stamping applications. As a 550 MPa yield cold rolled product, this specification is available in coil, sheet, and precision-blanked formats. Our ISO 9001:2015 certified facility triple-tests every coil (ID, OD, and center) to verify mechanical properties remain consistent throughout the entire length.

MS 50002-DPC 550Y-980T 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 550 MPa yield, the coating selection for MS 50002-DPC 550Y-980T should account for forming severity and post-stamping corrosion exposure in the final application.

MS 50002-DPC 550Y-980T at 550 MPa yield and 980 MPa tensile compares to MS 50002-LAC 550Y-620T (0 MPa lower yield at 550 MPa and 980 MPa vs 620 MPa tensile) and MS 50002-LAH 550Y-620T (0 MPa lower yield at 550 MPa and 980 MPa vs 620 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
