Steel M2 Mechanical Properties:

M2 high-speed steel is a tungsten-molybdenum tool steel. M2 is characterised by well-balanced toughness, wear resistance and red hardness properties.AISI M2 high-speed steel has largely replaced T1 in most applications due to its superior properties and advantageous pricing. M2 is medium-alloyed and is a good all-round performer with good machinability, in this respect it is superior to the high alloyed cold work steels.

  • M2 Steel Introduction:

    M2 High Speed Tool Steel is a general purpose molybdenum-type high speed steel exhibiting well-balanced toughness, wear resistance and red hardness properties. This grade is commonly used in cold work punches and dies and cutting applications involving high speed and light cuts.

  • Annealing:

    Heat the M2 high-speed steel to 850 - 900째C. Hold at temperature for at least two hours or one hour per 25 mm of thickness. Furnace cool slowly. The maximum hardness should be 248 Brinell.

    Stress relieving:

    Stress relieving M2 is recommended after machining or grinding and before hardening to minimise the chance of distortion. Heat the component to 600 - 700째C and soak well (for approximately two hours), then cool in air.

    Hardening:

    Pre heat the M2 in two steps; 450 - 500째C then 850 - 900째C. Then continue heating to the final hardening temperature of 1200 - 1250째C. Do not leave the steel too long at the hardening temperature. Quench in warm oil or brine to about 500째C then air cool down to room temperature.

    Tempering:

    Heat the M2 to the required tempering temperature, hold at temperature for at least two hours or one hour per 25 mm of thickness. Double tempering is recommended.

  • M2 Tool Steel Applications:

    Twist drills, taps, milling cutters, reamers, broaches, saws, and knives.
