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 A1011/A1011M HSLAS-F GR 50 (340)

ASTM A1011/A1011M HSLAS-F GR 50 (340) is a improved formability hslas-f grade 50 grade hot roll po steel conforming to the astm standards. At 340 MPa minimum yield strength, this is medium-strength structural steel for longitudinal rails, shotgun members, and frame reinforcement channels.

ASTM A1011/A1011M HSLAS-F GR 50 (340) carries the improved-formability HSLAS-F designation at 340 MPa yield. Compared to standard HSLA grades at equivalent strength levels, ASTM A1011/A1011M HSLAS-F GR 50 (340) delivers higher elongation values and better r-values (plastic strain ratios), enabling more complex stamping geometries while maintaining structural load-carrying capability.

Ameristeel carries ASTM A1011/A1011M HSLAS-F GR 50 (340) across a range of gauges and widths in hot roll po form, available as coils, sheets, or custom-cut blanks. With 340 MPa minimum yield strength, this improved formability hslas-f grade 50 specification requires precise handling and testing — our ISO 9001:2015 certified processes include third-party laboratory verification on every incoming coil.

ASTM A1011/A1011M HSLAS-F GR 50 (340) 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. At 340 MPa yield, the coating selection for ASTM A1011/A1011M HSLAS-F GR 50 (340) should account for forming severity and post-stamping corrosion exposure in the final application.

ASTM A1011/A1011M HSLAS-F GR 50 (340) at 340 MPa yield compares to ASTM A653/A653M HSLAS 340 (0 MPa lower yield at 340 MPa) and ASTM A653/A653M HSLAS-F 340 (0 MPa lower yield at 340 MPa). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.

ASTM A1011/A1011M HSLAS-F GR 50 (340) is widely used across structural construction, heavy equipment manufacturing, pressure vessel fabrication, bridge and infrastructure components, and automotive chassis applications. 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 A1011/A1011M HSLAS-F GR 50 (340) specifications with complete mill test reports and material certification.

Ameristeel offers in-house processing for ASTM A1011/A1011M HSLAS-F GR 50 (340) 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.
