O1 Tool Steel is the original oil-hardening, “non-shrinking” tool steel that can be hardened to the Rockwell C 65 range from a low austenitizing temperature. O1 is a general-purpose tool steel that is typically used in applications where alloy steels cannot provide sufficient hardness, strength, and wear resistance.
APPLICATIONS: Where greater dimensional stability in heat treatment or improved wear resistance is required, tool steels with higher alloy contents, such as A2 or D2 should be considered.
