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 WSD-M1A333-A4

WSD-M1A333-A4 is a extra high formability grade cold rolled steel conforming to the ford wss specifications.

Ameristeel maintains a deep inventory of WSD-M1A333-A4 in standard and custom gauges, available as coils, slit coils, sheets, or precision blanks. As a cold rolled product, WSD-M1A333-A4 offers the tight thickness tolerances and controlled surface finish critical for visible and semi-exposed automotive applications. Every coil is third-party tested under our ISO 9001:2015 quality system.

WSD-M1A333-A4 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 WSD-M1A333-A4 depends on your forming process, paint system, and end-use corrosion environment.

WSD-M1A333-A4 is listed alongside WSD-M1A333-A3 within this specification family. As a extra high formability designation, WSD-M1A333-A4 addresses specific cold rolled forming requirements that distinguish it from adjacent grades in ductility, surface quality, and mechanical property control.

WSD-M1A333-A4 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 WSD-M1A333-A4 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 WSD-M1A333-A4 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 for complex profiles and prototypes on our TRUMPF fiber laser systems, press brake forming on our TruBend series with up to 110-ton capacity and 120" bend length. 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.
