O1 Tool Steel Round

O1 tool steel is an oil hardening, cold work general purpose steel with easy machining properties and low hardening temperatures compared to other grades. O1 provides good wear resistance and toughness sufficient for standard tool and die applications making it a suitable choice for tooling with good tool life and econimcal production. In situations that require greater size stability during hardening, A2 should be considered. Some common applications include: bending dies, trimmer dies, perforators, broaches, blanking dies, forming dies, gages, cutting dies, bushings, forming rolls, knives, drawing dies, and embossing dies. Common trade names include Badger, Ketos, Truform, Keystone, Oilcraft, Presco, Colonial No. 6, Thyrodur 2510, Wando, Kiski, EXL-Die, BTR, Saratoga, Teenax, Keewatin. O1 rounds are supplied in a decarb free and annealed condition.
