ASTM A1008/A1008M GRADE 33 (230) TYPE 1 HSLA Grade 33 — Cold Rolled Steel

ASTM A1008/A1008M GRADE 33 (230) TYPE 1 is a hsla grade 33 grade cold rolled steel conforming to the astm standards. At 230 MPa minimum yield strength, this is structural-quality steel for inner body panels, dash panels, and trunk floor reinforcements.

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 33 (230) 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 33 (230) TYPE 1 include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

ASTM A1008/A1008M GRADE 33 (230) TYPE 1 at 230 MPa yield compares to ASTM A1008/A1008M GRADE 33 (230) TYPE 2 (0 MPa lower yield at 230 MPa) and ASTM A1008/A1008M GRADE 30 (205) (25 MPa higher yield at 205 MPa). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
