CHROMEWEAR 300 is an air-hardening tool steel developed for applications that require extremely high abrasion resistance. It far exceeds the wear-resistance properties of the air-hardening high-carbon high-chromium steels, and is even superior in wear resistance to the high wear-resistant AISI Type A7 (CHROMEWEAR) tool steel. Its many applications include brick-mold liners, granulator knives, liners for sand slingers and extrusion punches for ceramics. This datasheet provides information on composition and hardness. It also includes information on wear resistance as well as forming, heat treating, machining, and surface treatment. Filing Code: TS-392. Producer or source: Teledyne Vasco.
