What is O1 Tool Steel?
O1 Tool Steel is a cold-work, oil-hardening tool steel that delivers a balance of toughness, wear resistance, and machinability. Unlike air-hardening grades such as A2, O1 hardens in oil, which minimizes distortion and provides excellent dimensional stability.
Because of its affordable cost and ease of machining, O1 is one of the most widely used tool steels for general-purpose tooling.
