It is a superior quality steel which has excellent wear and abrasion resistance properties. Preheating temperature: 1200–1380°F (650–750°C). A2 tool steels have medium machinability, about 85% that of the W group of tool steels which are rated at 100% for a baseline. Heat to austenitizing temperature 2. A-2 also has excellent non-deforming properties. These characteristics make it a versatile tool steel that combines good performance and price. AISI SAE A-2 Tool Steel. Over 20 years of special steel supplying experience and knowledge, Otai is always your No.1 reliable supplier and partner for tool steel and alloy steel. A2 is typically used in hammers, knives, chuck jaws, dowel pins and more. AISI A2 tool steel is high-carbon, high alloy tool steel designed to have excellent wear resistance and toughness. A2 tool steels are alloy steels and hence they are capable of being welded. Avoid working below 899°C(1650°F). Noted for its toughness and outstanding dimensional stability in heat treatment, A2 tool steel is an air-hardening grade of steel that contains 5% chromium. Get a Fast Quote. The AISI - SAE grades of tool steel is the most common scale used to identify various grades of tool steel. Tool Steel, H13, 01, 2714, A2, D2, D3, Manufacturers, Distributors, Aviation Specialists, Sheffield UK A2 tool steel is an air hardening, cold work steel. This grade has improved wear resistance as compared to the O series (oil hardened) tool steels. An air hardening tool steel which, after heat treatment, offers a high abrasion resistance coupled with toughness. These characteristics have made A-2 a very popular and widely used material. 900 HV1. In applications require greater size stability, A2 steel is preferable than O1 tool steel. The chromium in drill rod replaces the oil hardening (O1 type). Furnace or Salt: 1725-1750°F (941-954°C) Soak for 30 minutes for the first inch (25.4 mm) of thickness, plus 15 minutes for each additional inch (25.4 mm).
