Phosphorus (P), 0. Sulfur (S), and the base metal Iron (Fe). Other designations of AISI M2 tool steel include UNS T1. AISI M2. Steels can either be cast directly to shape, or into ingots which are reheated and hot worked into a wrought shape by forging, extrusion, rolling, or other processes.
Wrought steels are the most common engineering material used, and come in a variety of forms with different finishes and properties. Tool steels typically have excess carbides (carbon alloys) which make them hard and wear- resistant.
Most tool steels are used in a heat- treated state, generally hardened and tempered. The typical density of tool steels ranges from 7. The wide range of ultimate tensile strength is largely due to different heat treatment conditions.

A steels. Sufficient amounts of manganese, molybdenum and chromium present in group A steels provide full hardness in sections comprising thickness of at least 1. Carbon content in group A steels range from 0. These steels are provided with air hardening characteristics that allow minimum cracking and distortion on quenching. A2 air- hardening, medium- alloy, cold- work tool steels are a type of group A steels containing molybdenum and chromium. The carbon content in A2 tool steels is high. A2 tool steels can be deep hardened in order to minimize distortion.
This article will provide an overview of M2 molybdenum high speed tool steel. The mechanical properties of M2 molybdenum high speed tool steel are tabulated below. Materials; Applications; Industries; AZojomo. A4, A6, A7, A8, A9, and A10 form air-hardening, medium alloy, cold work steels or group A steels. Equivalent materials to A2 tool steels are.

Tempering. A2 tool steels are heat treated at temperatures ranging from 1. However, welding of A2 tool steels are not much preferred due to the risk of crack formation. The following guidelines can be followed during the welding of A2 steels: A. Welding in order to harden the soft annealed A2 tool steel.
Heat to austenitizing temperature. Cool to approx. Repair welding of A2 tool steel in hardened and tempered condition Preheat to the tempering temperature (min. Soak the steels for 3 hours.
Cool in air to approx. Soak for 2 hours. Hard facing electrode C.
Welding of soft annealed A2 tool steel. Preheat to 3. 00- 5. These tool steels should not be forged below 8. Forming. Forming of A2 tool steels is carried out by machining or hot forging.
Machinability. A2 tool steels have medium machinability. Heat Treatment. A2 tool steels are heated slowly to 7. A2 tool steels are further held at 9.
