ASTM A1008/A1008M GRADE 70 (480) CLASS 2 HSLA Grade 70 — Cold Rolled Steel

ASTM A1008/A1008M GRADE 70 (480) CLASS 2 is a hsla grade 70 grade cold rolled steel conforming to the astm standards. At 480 MPa minimum yield strength, this is advanced-strength steel for B-pillar reinforcements, side impact beams, and roof bow structures.

Class two permits a wider mechanical property range with relaxed yield tolerance bands, offering manufacturing flexibility for applications where close yield control is less critical.

The Class 2 designation indicates wider mechanical property tolerance bands with manufacturing flexibility for general structural use. Within the ASTM family, different class numbers reflect progressively different ductility and elongation requirements to suit varying stamping complexity.

ASTM A1008/A1008M GRADE 70 (480) CLASS 2 at 480 MPa yield compares to ASTM A653/A653M HSLAS 480 (0 MPa lower yield at 480 MPa) and ASTM A653/A653M HSLAS-F 480 (0 MPa lower yield at 480 MPa). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
