O1 Tool Steel DCF Round

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. 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, drawing dies, and embossing dies.
