Abstract AISI Type P20 is a chromium-molybdenum tool steel of medium carbon content. It usually is supplied in the prehardened condition (about 300 Brinell) so that the cavity can be machined and the mold or die placed directly in service; however, for some uses further treatments are employed. It is produced to high-quality tool-steel standards to permit a high luster to be achieved on the surface of the polished die cavity. P20 is used for molds for plastics and for die-casting dies for zinc and other low-temperature casting alloys. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, and machining. Filing Code: TS-393. Producer or source: Tool steel mills.

Abstract AISI Type M7 is a molybdenum type of high-speed steel. It is somewhat similar to AISI Type M1 tool steel but with higher percentages of carbon and vanadium to provide an improvement over AISI Type M1 in cutting characteristics without a significant loss in toughness. It is suitable for a wide variety of cutting-tool applications where improved resistance to abrasion is required. The many uses of Type M7 include twist drills, end mills, shear blades, punches, milling cutters, lathe tools, taps and reamers. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: TS-483. Producer or source: Tool steel mills. See also Alloy Digest TS-468, January 1987.

Aisi Type

Abstract AISI Type S2 is a water-hardening tool steel with extreme toughness and resistance to shock loading. Even at a hardness of Rockwell C 59-60, it will bend before it breaks. When hardened in medium-size and large-size pieces, it acquires a hard case and a tough core. Sizes under 3/4-inch (19mm) diameter will water harden to the center. The extreme toughness of Type S2 makes it suitable for use in many applications where no other tool steel will hold up. Its many uses include chisels, rivet busters, spike mauls, screw drivers, punches and sledges. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, machining, and joining.

Abstract UNS No. T30407 is a high-carbon chromium cold-work tool steel containing vanadium (4.0%) and molybdenum (1.0%). Its carbon and vanadium form a vanadium carbide that provides war resistance many times greater than that of UNS No. T30403 (AISI Type D3). UNS No. T30407 was developed for applications where extreme abrasive wear is needed. Its many applications include briquetting dies and punches, brick mold liners, pottery, tools, broaches, meat-chopper plates and cold-extrusion dies.

Abstract AISI Type 1.2 is a chromium-vanadium tool steel of modest hardenability and variable carbon content (nominally 0.50-1.10% carbon). At its lower carbon levels, it is used for tools requiring toughness and resistance to shock and vibration. At its higher carbon levels, it is recommended for resistance to abrasion, fatigue and wear. It is used for both hot-work and cold-work applications. Among its many uses are automotive gears, forgings, gun barrels, shafts, wrenches, chisels, punches, lathe spindles, axes, shear blades, dies, files, reamers and drills.
