TM-2011 HR3-180-270-S Mild Steel — Hot Rolled Steel

TM-2011 HR3-180-270-S is a mild steel grade hot rolled steel conforming to the tesla material specifications. At 180 MPa minimum yield strength, this is formable mild steel suited for door inners, floor pans, and moderate-draw closure panels, with gentle forming loads and excellent surface finish retention for Class A exposed surfaces.

The Class 3 designation indicates deep drawing quality for complex formed parts. Within the TM family, different class numbers reflect progressively different ductility and elongation requirements to suit varying stamping complexity.

Ameristeel stocks TM-2011 HR3-180-270-S in a range of thicknesses and widths for structural and forming applications. As a hot rolled product, this specification is supplied in coils, cut sheets, or blanked parts. Our dedicated purchasing team sources TM-2011 HR3-180-270-S through direct mill relationships, and every incoming coil is third-party tested under our ISO 9001:2015 quality management system.

TM-2011 HR3-180-270-S is supplied with the following coating options: hot-dip galvanized (zinc) for general corrosion resistance; galvanneal (zinc-iron alloy) for superior paint adhesion and weldability; electrogalvanized for precise coating weight control and smooth surface finish. At 180 MPa yield, the coating selection for TM-2011 HR3-180-270-S should account for forming severity and post-stamping corrosion exposure in the final application.

TM-2011 HR3-180-270-S at 180 MPa yield and 270 MPa tensile compares to TM-2011 HR2-180-270-S (0 MPa lower yield at 180 MPa and 270 MPa vs 270 MPa tensile) and TM-2011 CR-180-290-BH-S (0 MPa lower yield at 180 MPa and 270 MPa vs 290 MPa tensile). Selecting the right grade depends on the balance between strength requirements and forming complexity for your specific stamping application.
