TM-2011 HR-440-580-FB-S Ferritic Bainitic — Hot Rolled Steel

TM-2011 HR-440-580-FB-S is a ferritic bainitic grade hot rolled steel conforming to the tesla material specifications. At 440 MPa minimum yield strength, this is advanced-strength steel for B-pillar reinforcements, side impact beams, and roof bow structures, with substantial tensile reserve for energy-absorbing crush zones and progressive deformation members.

Ameristeel maintains inventory of TM-2011 HR-440-580-FB-S 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 TM-2011 HR-440-580-FB-S include Uncoated, Galvanized, Electrogalvanized, Galvannealed, providing corrosion protection and surface preparation suited to your manufacturing process requirements.

TM-2011 HR-440-580-FB-S at 440 MPa yield and 580 MPa tensile compares to TM-2011 CR-440-780-DP-S (0 MPa lower yield at 440 MPa and 580 MPa vs 780 MPa tensile) and TM-2011 CR-450-780-TR-S (10 MPa lower yield at 450 MPa and 580 MPa vs 780 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
