Abstract RED CUT COBALT steel is made by adding 5% cobalt to the conventional 18% tungsten -4% chromium-1% vanadium high-speed steel. Cobalt increases hot or red hardness and thus enables the tool to maintain a higher hardness at elevated temperatures. This steel is best adapted for hogging cuts or where the temperature of the cutting point of the tool in increased greatly. It is well adapted for tools to be used for reaming cast-iron engine cylinders, turning alloy steel or cast iron and cutting nonferrous alloys at high speeds. This datasheet provides information on composition, physical properties, and hardness as well as fracture toughness. It also includes information on forming, heat treating, and machining.

Abstract This article introduces some of the general sources of heat treating problems with particular emphasis on problems caused by the actual heat treating process and the significant thermal and transformation stresses within a heat treated part. It addresses the design and material factors that cause a part to fail during heat treatment. The article discusses the problems associated with heating and furnaces, quenching media, quenching stresses, hardenability, tempering, carburizing, carbonitriding, and nitriding as well as potential stainless steel problems and problems associated with nonferrous heat treatments. The processes involved in cold working of certain ferrous and nonferrous alloys are also covered.

Abstract Ispat Inland MartINsite is a low-carbon cold-rolled ultrahigh-strength steel available in four grades with minimum tensile strengths of 900 MPa (130 ksi) (M-130), 1100 MPa (160 ksi) (M-160), 1310 MPa (190 ksi) (M-190), and 1520 MPa (220 psi) (M-220). This steel can be used where high strength and/or lightweight are required and can substitute for high-carbon alloy steels, spring steels, and some nonferrous alloys at significant savings in cost. Electrosite is an electrogalvanized form of M-190. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and bend strength. It also includes information on wear resistance as well as heat treating and surface treatment. Filing Code: CS-62. Producer or source: Ispat Inland Inc.

Abstract AISI Type T4 is made by adding 5% cobalt to the conventional 18% tungsten-4% chromium-1% vanadium (AISI Type T1) tool steel. The cobalt dissolves in the ferrite and strengthens the matrix of the steel whereas the other alloying elements form carbides. Thus the cobalt increases the hot or red hardness, thereby enabling the tool to maintain a higher hardness at elevated temperatures. Type T4 is well adapted for cutting hard, gritty materials such as cast iron or other abrasive materials and for cutting nonferrous alloys at high speeds. This datasheet provides information on composition, physical properties, and hardness as well as fracture toughness. It also includes information on forming, heat treating, and machining.

Machining Operations

Abstract MOLITE 42 is a molybdenum-type super high-speed steel. It has a well-balanced composition designed to give superior performance when used for difficult machining operations. It can be heat treated to a hardness level of Rockwell C 68-70 giving excellent red hardness while maintaining moderate toughness. MOLITE is especially recommended for tools used in the machining of high-strength steels, prehardened steels and exotic ferrous and nonferrous alloys such as are used in aircraft and missile work. It is also recommended for ordinary machining jobs requiring long production runs. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-487. Producer or source: Columbia Tool Steel Company.
