MS 50002-MCH 600Y-650T Hot Rolled Small Grain — Hot Rolled Steel

MS 50002-MCH 600Y-650T is a hot rolled small grain grade hot rolled steel conforming to the fiat/chrysler specifications. At 600 MPa minimum yield strength, this is ultra-high-strength steel for door intrusion beams, bumper reinforcements, and tunnel structures, with high tensile capacity for safety-critical crash path components requiring controlled collapse behavior.

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 600Y-650T 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 600Y-650T 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 600Y-650T include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

MS 50002-MCH 600Y-650T at 600 MPa yield and 650 MPa tensile compares to MS 50002-LAC 550Y-620T (50 MPa higher yield at 550 MPa and 650 MPa vs 620 MPa tensile) and MS 50002-LAH 550Y-620T (50 MPa higher yield at 550 MPa and 650 MPa vs 620 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
