Import D2 Tool Steel — Buy in Bulk from Supplier in China

D2 tool steel from Shanghai Unite Steel is a high-carbon, high-chromium cold work alloy designed for demanding applications where wear resistance and dimensional stability are critical. The supplier’s material is provided in sizes ranging from 5 to 1800 mm, with weight and dimensions tailored to customer requirements. This grade undergoes controlled heating and cooling cycles to prevent excessive carburization or decarburization during processing, ensuring uniformity.

The composition of D2 typically includes approximately 1.5% carbon and 12% chromium, delivering exceptional hardness and moderate corrosion resistance when polished. Standard industry grades for this alloy include AISI, ASTM, BS, DIN, GB and JIS classifications, with typical hardness achievable in the 60-62 HRC range after heat treatment. The material’s air-hardening property reduces distortion during quenching, making it suitable for intricate dies and punches.

Buy this steel for use in blanking dies, forming rolls, cutting tools and shear blades where abrasion resistance is paramount. Importers in the tooling, automotive and manufacturing sectors source D2 for high-volume production runs.
