O2 Tool Steel is a high-carbon, oil-hardening cold work tool steel known for its excellent wear resistance, superior edge retention, and good dimensional stability after heat treatment. It is widely used in cutting tools, blanking dies, punches, shear blades, gauges, and precision tooling where consistent performance and fine surface finish are critical.
As a reliable O2 Tool Steel supplier and stockist, we provide high-quality material sourced from trusted mills, ensuring consistent chemistry, tight tolerances, and dependable performance across demanding industrial applications. Our O2 Tool Steel is available in a variety of sizes and formats to meet the needs of toolmakers, OEMs, and engineering companies worldwide.
O2 Tool Steel is an oil-hardening cold work tool steel with a relatively high carbon content and alloying elements that improve hardness and wear resistance. Compared to O1 Tool Steel, O2 offers enhanced wear resistance while still maintaining good machinability and toughness.
Because it hardens in oil, O2 Tool Steel experiences less distortion and cracking during heat treatment compared to water-hardening grades. This makes it especially suitable for precision tools and close-tolerance components.
