AISI Type O7 is a high-carbon, low-alloy tools designed for many types of cold-work cutting tools where the high-alloy, high-speed steels are not required. It has moderate hardenability, develops high hardness, holds a keen cutting edge and has excellent resistance to abrasion. Type O7 is used for a wide range of cold-working tools such as broaches, blanking dies, punches, thread-rolling dies, paper knives and wood-working tools. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-404. Producer or source: Tool steel mills.
