Ford WSS Specifications

Ford Motor Company World Specification Standards (WSS-MIA) define automotive-grade steel for vehicle body and structural applications. Ameristeel supplies Ford WSS steel grades spanning commercial quality through ultra-high-strength dual-phase (AHSS) tiers, in cold rolled and hot rolled forms with galvanized, galvanneal, and electrogalvanized coating options. These standards cover drawing-quality panels, bake-hardenable outer body steels, HSLA structural members, interstitial-free formability grades, and advanced high-strength crash components. Available in coils, sheets, and precision-cut blanks from our Fraser, MI service center, with slitting and cut-to-length processing for prototype quantities and full production runs.

About WSS-MIA367-A50

WSS-MIA367-A50 is a hsla grade 80 grade hot rolled steel conforming to the ford wss specifications.

WSS-MIA367-A50 specifies the highest hot-rolled HSLA strength tier in the A4x/A5x series at approximately 550 MPa minimum yield, reserved for the most demanding underbody structural applications including full-length frame rails on body-on-frame platforms and heavy towing package reinforcement structures.

Ameristeel stocks WSS-MIA367-A50 in a range of thicknesses and widths for structural and forming applications. As a hot rolled product, this specification is supplied in coils, cut sheets, or blanked parts. Our dedicated purchasing team sources WSS-MIA367-A50 through direct mill relationships, and every incoming coil is third-party tested under our ISO 9001:2015 quality management system.

WSS-MIA367-A50 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. The right coating choice for WSS-MIA367-A50 depends on your forming process, paint system, and end-use corrosion environment.

WSS-MIA367-A50 is listed alongside WSS-MIA367-A49 and WSS-MIA368-A11 within this specification family. As a hsla grade 80 designation, WSS-MIA367-A50 addresses specific hot rolled forming requirements that distinguish it from adjacent grades in ductility, surface quality, and mechanical property control.

WSS-MIA367-A50 is an OEM-specific grade developed to meet Ford engineering requirements for vehicle body and structural applications. Ameristeel supplies Ford-specified steel grades directly to Tier 1 and Tier 2 automotive suppliers throughout Southeast Michigan, with full material traceability and third-party test reports on every coil. Our Fraser, MI steel processing facility maintains dedicated inventory of WSS-MIA367-A50 to support just-in-time delivery schedules, and our ISO 9001:2015 quality system ensures that every shipment meets the exact mechanical property, surface quality, and dimensional tolerances required by Ford production standards.

Ameristeel offers in-house processing for WSS-MIA367-A50 at our Warren and Fraser, Michigan facilities. Available processing capabilities include precision slitting to custom widths on our multi-cut blanking line, cut-to-length sheet processing for exact dimensional requirements, laser cutting of high-strength profiles on our TRUMPF fiber laser with up to 4kW power, shear processing for rapid sheet production. From raw material sourcing through finished part delivery, Ameristeel provides a single-source solution — eliminating the need to coordinate between separate steel suppliers, service centers, and fabrication shops.
