CPM Rex T15 is a tungsten-type high-speed steel containing high carbon and vanadium for very high hardness and maximum wear resistance, and cobalt for good red hardness. It is now made exclusively by Crucible’s particle metallurgy process, resulting in improved quality and grindability. This alloy was designed for use in difficult machining operations requiring heavy-duty cuts, high speeds and feeds, and for difficult-to-machine materials that are high in hardness and abrasion resistance. This datasheet revision updates chemistry, properties, and the benefits of high sulfur (HS). This datasheet provides information on composition, physical properties, hardness, elasticity, and bend strength as well as fracture toughness. It also includes information on wear resistance as well as forming, heat treating, and machining. Filing Code: TS-249. Producer or source: Crucible Service Centers. Originally published as CPM REX T15, January 1973, revised March 2007.

FAGERSTA WKE-45 is a tungsten-molybdenum high-speed steel containing 11% cobalt. It has greater red hardness and more wear resistance than almost any other high-speed steel and has adequate (medium) toughness. It is used mainly for lathe tools (for example, tool bits) where maximum wear resistance and red hardness are required. It is particularly suitable for working very hard and wear-inducing materials, including stainless steels. This datasheet provides information on composition and hardness. It also includes information on forming, heat treating, and machining. Filing Code: TS-317. Producer or source: Fagersta Steels Inc..

SPEED STAR is a fine-grained molybdenum-tungsten high-speed steel with an excellent combination of wear resistance and toughness. Among its many uses are lathe tools, drills, gear cutters and wood knives. This datasheet provides information on composition, physical properties, hardness, elasticity, and compressive strength as well as fracture toughness. It also includes information on forming, heat treating, and machining. Filing Code: TS-303. Producer or source: Carpenter.

Panther 5 is a 5% cobalt, high-carbon, high-vanadium, tungsten high-speed steel. Because of its excellent red hardness, higher cutting speeds can be used with Panther 5 than with the regular high-speed steels. Heat treating Panther 5 to its maximum hardness will provide long tool life. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on forming, heat treating, and machining. Filing Code: TS-301. Producer or source: Allegheny Ludlum Corporation.

REX M2 is a tungsten-molybdenum high-speed steel offering outstanding performance in all operations where a general-purpose high-speed steel is required. CPM REX M2, produced by the Crucible Particle Metallurgy Process, is an improved-quality product with greater hardness or finer grain size (depending on hardening temperature), better toughness and better grindability than the conventionally produced REX M2. Other characteristics and properties of the two products are very similar (See General Characteristics for more details). This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on forming, heat treating, and machining. Filing Code: TS-293. Producer or source: Crucible Specialty Metals Division, Colt Industries.

STAR-M0 M-2 is a tungsten-molybdenum high-speed steel of the 6-6-2 type having good red-hardness quality. This alloy corresponds to AISI type M2. Star-M0 is also available in Free-Machining type, to which sulfur, in the form of alloy sulphides, has been added for better machinability and increased tool life. This datasheet provides information on composition, hardness, tensile properties, and bend strength as well as fracture toughness, and deformation. It also includes information on forming, heat treating, machining, and joining. Filing Code: TS-112. Producer or source: Firth Sterling Corporation.

Circle-C is a high cobalt-tungsten steel having unusual red-hardness, and is particularly adapted for high production cutting tools. This datasheet provides information on composition, physical properties, and hardness. It also includes information on forming and heat treating. Filing Code: TS-110. Producer or source: Firth Sterling Corporation. See also CIRCLE C (T-5), Alloy Digest TS-502, October 1990.

VAN CUT is a tungsten-molybdenum high-speed steel adaptable to both heavy duty cutting and fine finishing. This datasheet provides information on composition and physical properties. It also includes information on forming, heat treating, and machining. Filing Code: TS-103. Producer or source: Vanadium Alloys Steel Company.

VAN CHIP is a tungsten-molybdenum high-speed steel of the M-3 (6-6-3) type containing high carbon and high vanadium. This high carbon and high vanadium content combine to produce superior abrasion resistance for more difficult cutting operations. This datasheet provides information on composition and hardness. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: TS-16. Producer or source: Firth Sterling Corporation.
