Products Description
M2 High Speed Tool Steel Flat Bar
AISI M2 Tool Steel is molybdenum based high-speed steel in tungsten–molybdenum series. HSS grade steel M2 is a medium alloyed high speed steel which has good machinability. The H-SS M2 chemical composition gives a good combination of well-balanced toughness, wear resistance and red hardness properties. Widely used for cutting tools such as twist drills, taps, milling cutters, saws, knives etc. Also commonly used in cold work punches and dies and cutting applications involving high speed and light cuts.
Grade M2 High Speed Steel is by far the most popular high speed steel replacing high speed steel grade T1 in most applications because of its superior properties and relative economy.

M2 High Speed Steel Applications:
The main use of high-speed steels continues to be in the manufacture of various cutting tools. Typical applications for M2 high speed steel are twist drills, reamers, broaching tools, taps, milling tools, metal saws. M2 is suitable for cold forming tools such as extrusion rams and dies, also widely used in all kinds of cutting tools, knife and punches and die applications, plastic moulds with elevated wear resistance and screws.

Forging of ASTM A600 High Speed Tool Steel M2
Pre heat M2 HSS steel slowly and uniformly to 850-900°C. The heat should then be increased more quickly to the forging temperature of 1050-1150°C. If during the forging the temperature of the M2 high speed tool steel material drops below 880-900°C, re-heating will be necessary. Cool the M2 steel component very slowly after forging.
Machinability of AISI M2 Tool Steel
Shaping of HSS M2 tool steels can be carried out using grinding methods. However, they have poor grinding capability and hence they are regarded as “medium” machinability tool steel under annealed conditions. The machinability of these tool steels M2 is only 50% of that of the easily machinable W group or water hardening tool steels.
