MS 50002-DPC 340Y-590T Dual Phase — Cold Rolled Steel

MS 50002-DPC 340Y-590T is a dual phase grade cold rolled steel conforming to the fiat/chrysler specifications. At 340 MPa minimum yield strength, this is medium-strength structural steel for longitudinal rails, shotgun members, and frame reinforcement channels, with substantial tensile reserve for energy-absorbing crush zones and progressive deformation 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.

As a Dual Phase steel, MS 50002-DPC 340Y-590T 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 340Y-590T 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 340Y-590T include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

MS 50002-DPC 340Y-590T at 340 MPa yield and 590 MPa tensile compares to MS 50002-LAC 340Y-410T (0 MPa lower yield at 340 MPa and 590 MPa vs 410 MPa tensile) and MS 50002-LAH 340Y-410T (0 MPa lower yield at 340 MPa and 590 MPa vs 410 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
