D6 cold work mold steel

D6 cold work mold steel is an air-hardening, oil-hardening tool steel designed for applications requiring high wear resistance and moderate toughness. This grade is supplied in the annealed condition, offering hardness around 212 HB typical, with a carbon content of approximately 2.10% and chromium at 12.0% typical. It maintains dimensional stability during heat treatment, making it suitable for intricate dies and punches where minimal distortion is critical.

The material’s uniform microstructure supports consistent performance in cold work tooling, including blanking dies, forming rolls, and shear blades. Its high chromium content provides deep hardenability, while vanadium additions refine grain size for improved wear resistance. Standard industry practice for D6 includes hardening at 950 - 1000°C, followed by tempering at 150 - 200°C to achieve a working hardness of 58 - 62 HRC typical. Surface treatments such as nitriding can further enhance wear life in abrasive environments.

Industries such as automotive stamping, metal forming, and precision engineering use D6 for tools exposed to severe abrasion and moderate impact. Buyers typically source this in rounds, flats, or pre-machined blocks, with common packaging in wooden crates or bundled bars. Confirm MOQ, lead times, and incoterms with the supplier, as these vary by order size and destination. Wuhan Fangyuan Special Steel Co., Ltd. supplies this grade from its facility in Wuhan, with stock available for immediate dispatch.
