Oil-hardening cold-worked steels are also known as Group O steels. Type O1 oil-hardening cold-worked steel contains chromium, manganese, and tungsten and is fairly inexpensive. O1 Tool Steel is the original hardening, non-shrinking tool steel that can be hardened from a low austenitizing temperature to the Rockwell C 65 range. O1 Tool Steel Bar is a general-purpose tool steel that is usually used in applications where alloy steels cannot provide adequate toughness, strength and wear resistance.
Forging of O1 Tool Steel Bar can be performed at 1038 degrees C (1900 degrees F) down to 857 degrees C (1575 degrees F) but not below 816 degrees C (1550 degrees F). O1 Tool Steel is extremely flexible and easy to handle in many respects, O1 has long been considered a general-purpose tool room steel. Low hardening temperatures enable in-plant heat treatment even where facilities are constrained, saving time and expense. O1 Die Steel Bar is a reliable alternative for multiple tooling and repair applications.
Tempering of O1 steels is performed at 177-260 degrees C (350-500 degrees F) to realize Rockwell C hardness of 62 to 57. O1 Tool and Die Steel Bar are primarily used for short-run tooling for blanking dies, cold forming dies, and cutting tools operating at ambient temperature.
