Stellantis-Specified Steel

What Is STELLANTIS-Specified Steel?

MST Steel supplies a range of Stellantis-specified steel grades engineered to meet the rigorous performance, quality, and manufacturability standards required by today’s automotive OEMs and tier suppliers. “Stellantis-Specified Steel” refers to a family of material types — including aluminized, automotive cold rolled steel, electro galvanized, galvannealed, hot dipped galvanized, and hot rolled steels — that have been validated for use in critical Stellantis applications through controlled chemistry, coating integrity, surface quality, and mechanical properties. This includes aluminized steel rolls for automotive applications as well as material solutions aligned with global manufacturing requirements, including select ASTM steel sheets and coils used across demanding OEM production programs.

Stellantis-Specified Steel is defined by:

Fit-for-function performance: Each grade is tailored to specific requirements such as corrosion resistance, heat tolerance, surface finish, and structural strength.
Precise surface and coating control: Automotive applications demand tight coating weight distribution, uniformity, and adhesion to support downstream processes like forming, welding, and painting.
OEM traceability and consistency: MST Steel’s supply of Stellantis-specified Steel adheres to documented specifications and quality checks to ensure consistency from coil to finished component.

These steel types are used broadly across the vehicle body, chassis, thermal management systems, and structural assemblies — helping manufacturers achieve durability, safety, and finish quality while optimizing total system cost. Whether supplying uncoated cold rolled for interior stampings or advanced aluminized grades for exhaust systems, MST Steel’s Stellantis-approved materials deliver the performance and supply reliability that automotive production demands. For specialized applications requiring corrosion-resistant DIN steel, MST Steel helps manufacturers evaluate specification compatibility and understand how to select steel for your application based on performance, formability, and long-term durability requirements.
