ASTM Standards

American Society for Testing and Materials (ASTM) standards govern steel quality, testing methods, and mechanical performance requirements. Ameristeel supplies a broad range of ASTM-graded flat-rolled steel products from our Fraser, MI facility, including cold rolled and hot rolled forming steels, galvanized and galvanneal coated grades, HSLA structural grades, and improved-formability variants. Available in coils, sheets, and processed blanks with slitting and cut-to-length services for prototype runs and high-volume production alike. ASTM specifications are the benchmark for steel procurement across automotive stamping, construction, and industrial manufacturing sectors throughout Warren, Sterling Heights, and greater Southeast Michigan.

About ASTM A1008/A1008M CS TYPE B

ASTM A1008/A1008M CS TYPE B is a commercial quality grade cold rolled steel conforming to the astm standards.

Type B specifies steel produced to standard deoxidation practice, suitable for unexposed structural applications where aging resistance is less critical.

Ameristeel maintains a deep inventory of ASTM A1008/A1008M CS TYPE B in standard and custom gauges, available as coils, slit coils, sheets, or precision blanks. As a cold rolled product, ASTM A1008/A1008M CS TYPE B 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.

ASTM A1008/A1008M CS TYPE B 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 ASTM A1008/A1008M CS TYPE B depends on your forming process, paint system, and end-use corrosion environment.

ASTM A1008/A1008M CS TYPE B is listed alongside ASTM A1008/A1008M CS TYPE A and ASTM A1008/A1008M GRADE 25 (170) within this specification family. As a commercial quality designation, ASTM A1008/A1008M CS TYPE B addresses specific cold rolled forming requirements that distinguish it from adjacent grades in ductility, surface quality, and mechanical property control.

ASTM A1008/A1008M CS TYPE B is widely used across automotive body panels, appliance housings, furniture manufacturing, and precision-formed industrial components. Ameristeel sources and stocks this grade at our Fraser, MI steel processing center, with the ability to supply production quantities, prototype runs, and custom-processed orders. Whether you need full coils, slit-to-width coils, cut-to-length sheets, or precision blanks, our team can fulfill orders to ASTM A1008/A1008M CS TYPE B specifications with complete mill test reports and material certification.

Ameristeel offers in-house processing for ASTM A1008/A1008M CS TYPE B 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.
