Cr12MoV SKD11 D2 DC53 Cold Work Tool Steel Round Bar 4–200mm Diameter High Hardness Wear Resistant Punch and Die Steel

Cr12MoV, SKD11, D2, and DC53 cold work tool steel round bars are high-performance alloy tool steels designed for applications requiring extreme wear resistance, high hardness, and dimensional stability. These tool steel round bars are widely used in manufacturing punches, dies, cutting blades, forming tools, and precision mould inserts that operate under high pressure and friction conditions. Each grade offers unique advantages: Cr12MoV and D2 provide exceptional wear resistance, SKD11 offers balanced toughness and hardness, and DC53 delivers improved toughness to prevent chipping in precision cold work tools.
Our cold work tool steel round bars are manufactured using advanced refining and rolling technologies to ensure high purity, uniform carbide distribution, and stable internal structure. The round bars are supplied in annealed condition for excellent machinability, allowing easy turning, milling, and grinding before final heat treatment. After quenching and tempering, these tool steel round bars reach hardness levels of 60–62 HRC, providing outstanding wear life and resistance to deformation. Fine grain structure enhances toughness, reducing the risk of cracking during high-speed stamping and cutting operations.
Available in diameters from 4mm to 200mm, our Cr12MoV, SKD11, D2, and DC53 tool steel round bars support a wide range of tool and mould components. Precision ground round bars offer tight dimensional tolerance for direct use in high-precision tools. We provide customized cutting, centerless grinding, and heat treatment services to meet specific application requirements. Whether for manufacturing stamping punches, cutting dies, or precision mould parts, these tool steel round bars deliver consistent performance, long service life, and excellent cost efficiency for industrial tooling and mould making applications.
