Description
M3 Type 2 is a tungsten moly high speed steel/" target="_blank" class="keylink">tool steel designed to provide the great wear resistance required for severe cutting operations. With a raised C and V content. Because of this the steel has optimum durability and cutting performance.

Applications
It is used for high performance mills, reamers, broaches for processing hard materials as well as in the area of cold work steel e.g. for piercing dies in the manufacture of nuts.

Physical properties (avarage values) at ambient temperature
Density [g/cm3]: 8.07

Coefficient of Linear Thermal Expansion 10-6 oC-1

 

20-100oC 20-200oC 20-300oC 20-400oC 20-500oC 20-600oC 20-700oC
11.7 11.9 12.3 12.8 13.0 13.0 13.0

Soft Annealing
Heat to 820-860oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 280.

Hardening
1st pre-heating: 400oC, 2nd pre-heating: 850oC and 3rd pre-heating: 850oC and 1050oC. Harden from a temperature of 1190-130oC followed by oil or air quenching or warm bath at 550oC/air.

Tempering
Tempering temperature: 540-570oC, at least 3 times. Hardness after tempering is 64-66 HRC.

Tempering Temperature (oC) vs. Hardness (HRC)

Forging
Hot forming temperature: 1100-900oC.

Machinability
M3 type 2 is classified as a "medium" machinability steel/" target="_blank" class="keylink">tool steel in the annealed condition. It may be shaped by grinding but is relatively poor in regard to capability of being ground. Its machinability rating is 50% as compared to the W group water hardening steel.

Corrosion Resistance
Not normally employed in applications requiring corrosion resistance.

Welding
Consult the alloy supplier for information on the advisability of welding.
