YG8 tungsten steel main ingredient is tungsten carbide, titanium carbide (TiC) and cobalt. Their grades by the "YT" ("hard titanium" word Pinyin prefix) and the average content of titanium carbide composition. For example, YT15, represents the average WTi = 15%, the rest of the content of tungsten carbide and cobalt titanium tungsten carbide cobalt. ③ Tungsten Titanium Tantalum (Niobium) is the main component class tungsten carbide, titanium carbide, tantalum (or niobium carbides), and cobalt. Such carbide, also known as common or universal carbide carbide. Their grades by the "YW" ("hard", "million" word Pinyin prefix) plus sequence number, for as YW1. YG8 tungsten steel chemical composition WC: 92 Co: 8 mechanical properties of density / (g/cm3) :14.5-14 .9 hardness (HRA): 89 Bending strength (σbb / MPa): 1500 Impact toughness σK / (J/cm2): 2.5 tungsten steel tungsten steel products product deformation and bending deformation and bending deformation and bending tungsten steel products may be the reason for 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. 6, the contraction coefficient.
