The main causes of quenching deformation of tungsten steel die steel are thermal stress, structural stress, and of course, stress caused by gravity and external stress, which is a large deformation of the die.

Tungsten steel mold:

The service life of tungsten steel die is ten times or even dozens of times that of steel die. Tungsten steel dies only have high hardness, high strength, corrosion resistance, high temperature resistance and small expansion coefficient, and generally use tungsten steel containing tungsten and cobalt.

The first type is tungsten steel wire drawing die, which accounts for the vast majority of tungsten steel dies. At present, the main brands of drawing dies in China are YG8, YG6 and YG3, followed by YG 15, YG6X and YG3X. Some new brands have been developed, such as YL for high-speed wire drawing, and imported CS05(YLO.5), CG20(YL20) and CG40 (YL30). K 10、ZK20/ZK30 .

The second type of dies are cold heading and stamping dies and forming dies. The main brands are YC20C, YG20, YG 15, CT35, YJT30, MO 15.

The third type of molds are non-magnetic alloy molds used to produce magnetic materials, such as YSN series (including 20, 25, 30, 35 and 40) and steel bonded non-magnetic mold brand TMF.
