AL TECH A-HT is a tool steel for difficult cold-work applications. It is somewhat similar to AISI Type A2 in alloy content but with increased wear resistance. Additions of titanium and tungsten produce hard, long-wearing carbides that help to decrease galling and metal pick-up. The main advantages of AL TECH A-HT are: (1) Very high wear resistance, (2) Good toughness, (3) Air hardening and (4) Low distortion in heat treatment. A-HT is used where better wear resistance is required than is attainable using AISI Type A2 or better toughness than AISI Type D2. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and compressive strength as well as fracture toughness. It also includes information on forming, heat treating, and machining. Filing Code: TS-457. Producer or source: AL Tech Specialty Steel Corporation.

17Cr-4Ni EZ is a precipitation hardening stainless steel offering engineers and designers a wide selection of strength and hardness levels. A simple one-step aging treatment provides end users a unique combination of strength, toughness, and corrosion resistance. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness, creep, and fatigue. It also includes information on low and high temperature performance, and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-551.

ONTARIO is an air-hardening die steel of the high-carbon high-chromium type. It has high hardness, high resistance to abrasion and excellent nondeforming characteristics. It is suited for a wide range of applications in which high abrasion resistance must be combined with high compressive strength and safety in hardening. Typical uses are cold-forming dies, forming rolls, thread-rolling dies, slitters and gages. 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-323. Producer or source: AL Tech Specialty Steel Corporation.
