TM-2011 CR-180-290-BH-S Bake Hardenable — Cold Rolled Steel

TM-2011 CR-180-290-BH-S is a bake hardenable grade cold 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.

TM-2011 CR-180-290-BH-S is a Bake Hardenable steel at 180 MPa yield and 290 MPa tensile. During the paint-bake cycle (typically 170°C for 20 minutes), the yield strength of TM-2011 CR-180-290-BH-S increases through carbon atom pinning of dislocations, improving dent resistance in the finished cold rolled panel without sacrificing the formability needed during stamping.

Ameristeel maintains a deep inventory of TM-2011 CR-180-290-BH-S in standard and custom gauges, available as coils, slit coils, sheets, or precision blanks. As a cold rolled product, TM-2011 CR-180-290-BH-S offers the tight thickness tolerances and controlled surface finish critical for visible and semi-exposed automotive applications. Every coil is third-party tested under our ISO 9001:2015 quality system.

TM-2011 CR-180-290-BH-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 CR-180-290-BH-S should account for forming severity and post-stamping corrosion exposure in the final application.

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