About ASTM A1011/A1011 HSLAS GR65 (450) CLASS 2
ASTM A1011/A1011 HSLAS GR65 (450) CLASS 2 is a hsla grade 65 grade hot roll po steel conforming to the astm standards. At 450 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.
As a Low Alloy / HSLA steel, ASTM A1011/A1011 HSLAS GR65 (450) CLASS 2 offers a specific combination of strength and formability engineered for advanced automotive manufacturing. This advanced high-strength classification meets demanding structural performance requirements.
Ameristeel maintains inventory of ASTM A1011/A1011 HSLAS GR65 (450) CLASS 2 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 A1011/A1011 HSLAS GR65 (450) CLASS 2 include Galvanized, Galvanneal, Electrogalvanized, providing corrosion protection and surface preparation suited to your manufacturing process requirements.
ASTM A1011/A1011 HSLAS GR65 (450) CLASS 2 at 450 MPa yield compares to ASTM A1008/A1008M GRADE 65 (450) CLASS 1 (0 MPa lower yield at 450 MPa) and ASTM A1008/A1008M GRADE 65 (450) CLASS 2 (0 MPa lower yield at 450 MPa). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
