ASTM A1008/A1008M GRADE 40 (275) TYPE 1 HSLA Grade 40 — Cold Rolled Steel

ASTM A1008/A1008M GRADE 40 (275) TYPE 1 is a hsla grade 40 grade cold rolled steel conforming to the astm standards. At 275 MPa minimum yield strength, this is intermediate-strength steel for structural cross-members, seat mounting brackets, and suspension component interfaces.

Type 1 is produced with niobium (columbium) as the primary micro-alloying element, providing fine grain refinement through niobium carbonitride precipitation during hot rolling for consistent strength and formability.

Ameristeel maintains inventory of ASTM A1008/A1008M GRADE 40 (275) TYPE 1 in various gauges and widths, available as coils, sheets, or custom blanks. Our ISO 9001:2015 certified processes ensure consistent quality from prototype through production volumes.

Available coating options for ASTM A1008/A1008M GRADE 40 (275) TYPE 1 include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

ASTM A1008/A1008M GRADE 40 (275) TYPE 1 at 275 MPa yield compares to ASTM A653/A653M HSLAS 275 (0 MPa lower yield at 275 MPa) and ASTM A653/A653M HSLAS-F 275 (0 MPa lower yield at 275 MPa). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
