Alloy steel is called alloy steel when other alloy elements are added in addition to iron and carbon. An iron carbon alloy formed by adding one or more alloy elements on the basis of ordinary carbon steel. According to the different elements added and the appropriate processing technology, high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other special properties can be obtained.

The microstructure of 15CrMo steel in normal supply state is ferrite plus pearlite. During the long-term operation of 15CrMo steel in the working temperature range of 500 ºC - 550 ºC, pearlite spheroidization, redistribution of alloy elements between solid solution and carbide, and change of carbide phase structure will occur. The thermal strength and mechanical properties of 15CrMo steel will gradually decrease with the increase of pearlite spheroidization and depletion of alloy elements in solid solution, As a result, the material becomes worse and even invalid.

Due to its high hardness, 30CrNiMo8 is often used to produce high-end mechanical parts. In addition to manufacturing screws, mechanical arms, pistons, shafts and shafts, 30CrNiMo8 can also be used to manufacture mechanical parts. Due to its alloy steel content, 30CrNiMo8 can achieve high tensile strength. High temperature can be used to process 30CrNiMo8. In general, 30CrNiMo8 material is used for products with large wear. The oil and gas industry, aviation, mechanical engineering, chemical industry and shipbuilding industry all deal with corrosion problems, making 30CrNiMo8 a very useful material.Meide Import and Export Company is a professional supplier of metal materials.
