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

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.
