Hot work die steel H13, in the process of cooling with graphite milk or water? Is there a crack with water?
With softening resistance at high temperature, but the temperature is higher than 540 degrees Celsius (1000 degrees Fahrenheit) hardness decreased rapidly (i.e. the ability of working temperature of 540 DEG C);
The deformation of the heat treatment is small;(7) medium and high machinability;(8) medium decarburization resistance.Even more noticeable is that it can also be used to make important components in the aviation industry
(1) it has high hardenability and high toughness;(2) excellent thermal cracking resistance and water cooling in workplace;(3) with moderate abrasion resistance, but also can improve the surface hardness of carburizing or nitriding process, but slightly reduced anti cracking ability;(4) because of its low carbon content, the two hardening ability of tempering is poor;
