MS 50002-MCH 550Y-600T Hot Rolled Small Grain — Hot Rolled Steel

MS 50002-MCH 550Y-600T is a hot rolled small grain grade hot 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 substantial tensile reserve for energy-absorbing crush zones and progressive deformation members.

This specification uses the hot-rolled martensitic/complex-phase (MCH) process route with fine-grain microstructure for high-strength structural applications.

As a Martensitic / Complex Phase steel, MS 50002-MCH 550Y-600T offers a specific combination of strength and formability engineered for advanced automotive manufacturing. The predominantly martensitic microstructure delivers the highest strength levels for anti-intrusion and structural reinforcement.

Ameristeel maintains inventory of MS 50002-MCH 550Y-600T 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-MCH 550Y-600T include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

MS 50002-MCH 550Y-600T at 550 MPa yield and 600 MPa tensile compares to MS 50002-LAC 550Y-620T (0 MPa lower yield at 550 MPa and 600 MPa vs 620 MPa tensile) and MS 50002-LAH 550Y-620T (0 MPa lower yield at 550 MPa and 600 MPa vs 620 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
