ASTM A1008/A1008M GRADE 25 (170) Commercial Quality — Cold Rolled Steel

ASTM A1008/A1008M GRADE 25 (170) is a commercial quality grade cold rolled steel conforming to the astm standards. At 170 MPa minimum yield strength, this is formable mild steel suited for door inners, floor pans, and moderate-draw closure panels.

Ameristeel maintains a deep inventory of ASTM A1008/A1008M GRADE 25 (170) in standard and custom gauges, available as coils, slit coils, sheets, or precision blanks. As a cold rolled product, ASTM A1008/A1008M GRADE 25 (170) 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 GRADE 25 (170) 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 170 MPa yield, the coating selection for ASTM A1008/A1008M GRADE 25 (170) should account for forming severity and post-stamping corrosion exposure in the final application.

ASTM A1008/A1008M GRADE 25 (170) at 170 MPa yield compares to ASTM A1008/A1008M GRADE 30 (205) (35 MPa lower yield at 205 MPa) and ASTM A1008/A1008M GRADE 33 (230) TYPE 1 (60 MPa lower yield at 230 MPa). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.

ASTM A1008/A1008M GRADE 25 (170) 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 GRADE 25 (170) specifications with complete mill test reports and material certification.

Ameristeel offers in-house processing for ASTM A1008/A1008M GRADE 25 (170) 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.
