Grade: YT5 Hardness: 89.5 Metal content: 99.96 impurity content: 0.4 Usage: for carbon steel and alloy steel [including forgings. Stampings and castings, uneven surface of the skin] cutting of rough car. Rough planing, semi-intensive planing, rough milling. Deformation impact and flexural deformation of tungsten steel products for many reasons, and bending deformation of a product causes to specific conditions, sometimes a factor at play, sometimes many factors play a role, can not be generalized. Tungsten steel products may cause deformation and bending analysis from the following aspects: 1, carbon gradient. 2, the cobalt gradient. 3, the temperature gradient. 4, the pressure product density gradients. 5, put the boat properly. Contraction coefficient.
