Description
Capable of very high hardness values, this is a moly type
high speed tool steel. The alloy has excellent hot hardness
and wear resistance and is commonly employed to machine
difficult to machine materials including the superalloys.
Applications
Typically employed to machine the superalloys and exotic, M*2
is employed in drills, hobs, taps, end mills, milling
cutters, form and gear cutters, broaches and chasers.
Physical properties
(avarage values) at ambient temperature
Density [g/cm3]: 8.*1
Thermal conductivity [W/m.K]: *9.0
Coefficient of Linear Thermal Expansion ***6 oC*1

| 9.8 | *0.8 | *1.1 | *1.6 | *1.9 | *2.2 | *2.5 | *2.6 |
Soft
Annealing
Heat to ******0oC, cool slowly in furnace. This will produce
a maximum Brinell hardness of ******0.
Stress
Relieving
Stress relieving to remove machining stresses should be
carried out by heating to **0oC, holding for one hour at
heat, followed by air cooling. This operation is performed to
reduce distortion during heat treatment.
Hardening
Heat up to ******0oC, then preheat to **0oC, and to ***0oC.
Harden from a temperature of ********0oC followed by oil, air
quenching or warm bath **0oC. Hardness after quenching is
****8 HRC.
Transformation temperatures: Ac1=**0oC , Ac3=**5oC.

Hot forming temperature: *******2oC.
Machinability
Rated at *5% of a 1% carbon steel, the alloy, in its annealed
condition, can be turned, drilled, tapped, milled, broached
and threaded.
