Common classification of steel
There are many ways to classify commonly used steel forgings, usually according to its chemical composition, use, smelting method and metallographic structure. No matter what kind of classification method is adopted, we must adhere to the principle of "scientific and practical" and choose a reasonable classification method from the actual needs.

With the development of science and technology and industry, higher requirements are put forward for materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion resistance, wear resistance and other special physical and chemical properties. Carbon steel can no longer be completely fulfil requirements. Disadvantages of carbon steel:
