Tungsten steel mold in the course of its life is relatively strong, with very good corrosion resistance, high hardness and high strength, and so a series of excellent performance, especially its high hardness and wear resistance, even in the 500 ℃ temperature is also basically the same, at 1000 ℃ still have a high hardness.
Tungsten steel mold processing material tungsten steel is called carbide, mainly refers to at least one of the metal carbide composition of the sintered composite material, carbide component (or phase) grain size is usually between 0.2-10 microns , The carbide grains are bonded together using a metal binder.
Tungsten steel mold needs to meet the requirements of its working conditions, the wear-resistant blank in the mold cavity of the plastic deformation, the product will effectively along the cavity surface both flow and slide, which will make the cavity surface and The billet effectively produces its severe friction, which causes the mold to fail due to wear. So the wear resistance of the material is the most basic and most important performance of the mold.
Tungsten steel mold toughness, mold working conditions are mostly very bad, and some often bear a greater impact load, resulting in brittle fracture. In order to prevent the mold parts in the work suddenly brittle fracture, the mold to have a high strength and toughness. The toughness of the mold depends mainly on the carbon content of the material, grain size and tissue state.
Tungsten steel mold in use with a certain degree of fatigue fracture performance, the mold in the process of work, will be in the long-term role of cyclic stress, often directly lead to its fatigue fracture. Its form has a small energy multiple impact fatigue fracture, tensile fatigue fracture contact fatigue fracture and bending fatigue fracture. The fatigue fracture properties of the mold are mainly determined by its strength, toughness, hardness, and the content of inclusions in the material.
