BETHALLOY is a low-alloy oil-hardening tool steel. Because of its relatively low carbon content (for tool steels), it has slightly better shock resistance than more highly alloyed types and may be used wherever wear resistance can be sacrificed for moderately increased toughness. This datasheet provides information on composition and hardness as well as fracture toughness. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: TS-308. Producer or source: Bethlehem Steel Corporation.
