Tool Steel O1 Applications | Typically used for thread rolling dies and other intricate die shapes. |
Tool Steel O1 Machinability | As with all of the tool steel alloys the machinability of O1 is medium, similar to the low alloy steels. It has a machinability rating of about 85% that of the simple alloy water hardening tool steels (W group) which are rated at 100% for reference. |
Tool Steel O1 Forming | Forming is done by means of machining or hot forging. |
Tool Steel O1 Welding | O1 is an alloy steel and thus capable of being welded. Consult the alloy supplier for details. |
Tool Steel O1 Heat Treatment | Preheat slowly to 1200 F then raise the temperature to 1475 F and hold for 45 to 60 minutes. Remove and air cool (the alloy is air hardening as the quench medium). |
Tool Steel O1 Forging | The forging temperature range is rather narrow of A10. Forge at 1875 F down to 1650 F. Do not forge below 1600 F. |
Tool Steel O1 Hot Working | Other than forging it is not usual practice to hot work this alloy. Consult the alloy supplier regarding hot working. |
Tool Steel O1 Cold Working | The alloy may be cold worked in the annealed condition by conventional methods. |
Tool Steel O1 Annealing | Anneal at 1425 F and very slow furnace cool at a rate of 25 F per hour or less. |
Tool Steel O1 Aging | Not applicable to this alloy. |
Tool Steel O1 Tempering | Temper at 400 F to 800 F. This will result in developing a hardness of approximately Rockwell C 62 for the low temperature to Rockwell C 55 for the 800 F temper. |
Tool Steel O1 Hardening | This alloy hardens by heat treatment. See "Heat Treatment" and "Tempering". |
Other Comments | O1 alloy has high wear resistance and medium toughness. |
