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 super alloys.

Applications
Typically employed to machine the superalloys and exotic, M42 is employed in drills, hobs, taps, end mills, milling cutters, form and gear cutters, broaches and chasers. 

Physical properties (average values) at ambient temperature
Density [g/cm3]: 8.01
Thermal conductivity [W/m.K]: 19.0 


Soft Annealing
Heat to 820-880oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 230-300.

Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

Hardening
Heat up to 450-600oC, then preheat to 850oC, and to 1050oC. Harden from a temperature of 1160-1210oC followed by oil, air quenching or warm bath 550oC. Hardness after quenching is 66-68 HRC.
Transformation temperatures: Ac1=780oC, Ac3=855oC.

Tempering
Tempering temperature: 3 x 1 hour at 520-560oC.


Forging
Hot forming temperature: 1095-982oC. 

Machinability
Rated at 45% of a 1% carbon steel, the alloy, in its annealed condition, can be turned, drilled, tapped, milled, broached and threaded.

Corrosion resistance 
Not normally employed in applications requiring corrosion resistance.
