20CrH Steel Introduction
20CrH steel is a general purpose low alloy steel which is commonly used to manufacture automobile and other machineries. It is also used as a structural steel and castings. It is widely used in China and other countries for making high temperature components like bearing, shafts, crucibles, fasteners, gears and axles.
The 20CrH alloy steel is a chromium-molybdenum steel with a composition of 0.15-0.25% carbon, 0.80-1.2% manganese, 0.65-1.15% chromium, 0.20-0.30% molybdenum and 0.15-0.25% silicon. The alloying element in 20CrH steel is mainly used to increase the hardenability, tensile strength and toughness of the steel. It also helps in increasing the wear-resistance.
The 20CrH steel is a low alloy steel and is widely used in different applications. It is mainly used to manufacture parts that are used in machines and engines. It is also used as structural steel for making frames, columns, cross members and other structural components.
The 20CrH steel has a high alloy content. It has a high hot strength and excellent weldability. It is also resistant to corrosion, oxidation and wear. The 20CrH steel can be heat-treated and is capable of hardening up to 550°C.
The 20CrH steel has a low nitrogen content, which makes it ideal for automotive parts. It also has a high fatigue strength and high fatigue resistance.
In summary, the 20CrH steel is a versatile alloy steel and can be used for a variety of applications. It has a high hot strength and excellent weldability. It is resistant to corrosion, oxidation and wear and can be heat-treated to improve its hardness. The low nitrogen content of the steel makes it an excellent choice for parts used in automobiles and other machines. Its high fatigue strength and fatigue resistance gives it an edge over its counterparts.
