M2 Tool Steel | 1.3343 | HS-6-5-2C| SKH51

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.

We are one of leading AISI M2 HSS steel supplier and we can offer better quality and M2 alloy steel price for your various applications.

5. Forging of AISI M2 High Speed Steel

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.

6. Heat Treatment of M2 Steel HSS

• Anneal

Heat to 1600° F, soak thoroughly at heat. Furnace cool 25° F per hour to 900° F, air cool to room temperature. Approximate annealed hardness 241 Maximum Brinell.

Stress Relief of Unhardened Material: Heat slowly to 1200 to 1250° F. Soak for two hours per inch of thickness at heat. Slow cool (furnace cool if possible) to room temperature.

• Harden

Heat slowly to 1550° F, soak thoroughly, heat to 1850° F, soak thoroughly. Soak time in the furnace varies from a few minutes to 15 minutes, depending tool size, heat capacity of the furnace, and the size of the charge. – Heat to 2150 to 2200° F for max. toughness and minimum distortion. – Heat to 2250 to 2275° F for max. hardness and abrasion resistance.

• Quench

For full hardness, oil quench to 150-200° F. Air quench to 150° F. When quenching in hot salt maintain the quench just above the Ms temperature. After equalizing withdraw parts from the hot salt and air cooled to 150° F.

M2 Tool 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.
