About

CNC machined tool steel O1 is a high-carbon, oil-hardening tool steel designed for applications requiring excellent hardness, wear resistance, and dimensional stability. Known for its reliable heat treatment response and fine grain structure, tool steel O1 is widely used for precision tooling and mechanical components exposed to friction, stress, or repeated use.

Tool steel O1 provides a strong balance of hardness, toughness, and edge retention, allowing components to maintain precise geometry and surface integrity during service. While it offers limited corrosion resistance, protective coatings or controlled environments are typically used when environmental exposure is a concern.

Typical applications include cutting tools, dies, molds, punches, gauges, and wear-resistant machine components where durability, precision, and long service life are essential.
