Due to the suitable hardenability of the alloy structural steel, after the appropriate metal heat treatment, the microstructure is uniform soxite, bainite or very fine pearlite, thus having high tensile strength and yield ratio. (generally around 0.85), high toughness and fatigue strength, and low t

THE ROLE OF TUNGSTEN IN STEELTungsten has high melting point and high specific gravity. Tungsten carbide formed from tungsten and carbon has high hardness and wear resistance. When tungsten is added to tool steel, the red hardness and thermal strength can be significantly improved, and it can be use

The role of car beltThe function of the car belt is to support the upper and lower, the upper connection is the timing wheel of the engine cylinder head, the lower connection is the crankshaft timing wheel; the timing wheel is connected to the camshaft, and the camshaft has a cam, and its contact po

Common nitridingIt mainly refers to liquid nitriding. The most commonly used method is heating nitriding in salt bath, which is suitable for small batch production. There are many kinds of vacuum nitriding. Gas and ion nitriding belong to vacuum nitriding, which should be carried out after vacuum ev
