Properties
PM60 is a kind of ultra-pure powder metallurgy of alloy tool steel not containing high alloy. Its hardness ups to 70HRC, and it integrates have high compressive strength and high wear resistance that other materials do not have. In times of high-carbon tool steel scrap, PM60 is the best alternative.

Annealing treatment
Cooling to 700¡æ slowly at a rate of 10¡æ/h under protective atmosphere of 850-900¡æ,then air cooling.
Strain relief
Keeping in 600-700¡æ for 2 hours, and cooling to 500¡æ slowly.
Quenching
Preheating in two steps under protective atmosphere, 400-500¡æ and 850-900¡æ, and choosing the right temperature depending on the hardness and then cooling of austenite to 40-50¡æ.
Tempering
560¡æ 3 times, each time for at least 1 hour, cooling to room temperature after each tempered.
