With the development of science, technology, and industry, higher requirements have been put forward for materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion, wear, and other special physical and chemical properties. Carbon steel can no longer fully meet the requirements, so alloy steel plates have emerged.
