1.2344/SKD61/H13 steel is the most widely used and most representative hot work die steel, its main characteristics are:
(1) It has high hardenability and high toughness;
(2) Excellent resistance to thermal cracking, can be water-cooled in the workplace;
(3) With moderate wear resistance, carburizing or nitriding processes can also be used to increase the surface hardness, but the thermal cracking resistance should be slightly reduced;
(4) Because of its low carbon content, the secondary hardening ability during tempering is poor;
(5) It has anti-softening ability at a higher temperature, but the hardness decreases rapidly when the temperature is higher than 540 ºC (1000 ºC) (that is, the working temperature can be 540 ºC);
(6) The deformation of heat treatment is small;
(7) Medium and high machinability;
(8) Medium resistance to decarburization.
What is more noteworthy is that it can also be used to make important components in the aviation industry.
