SA387Gr22Cl2 steel plate has high strength, excellent corrosion resistance and good processing performance. It has high yield strength and tensile strength, which can meet the requirements of equipment used in harsh environments such as high temperature, high pressure and corrosion. In addition, SA387Gr22Cl2 steel plate has good low-temperature toughness and anti-fatigue properties, and can maintain stable performance in low-temperature environments.
SA387Gr22Cl2 steel plate is smelted by electric furnace + furnace refining. This smelting method can ensure the purity of steel, reduce the content of sulfur, phosphorus and other impurity elements, and improve the density and comprehensive performance of steel plate. At the same time, the use of extra-furnace refining technology can also accurately control the chemical composition of the molten steel and the content of trace elements, to provide a guarantee for the production of high-quality steel plates.
SA387Gr22Cl2 steel plate is delivered in heat treatment state, the specific delivery temperature should be negotiated according to the actual demand and user requirements. In general, the delivery temperature should be between 800℃~900℃. In the heat treatment process, parameters such as heating speed, holding time and cooling rate should be controlled to ensure that the steel plate obtains the best mechanical properties and corrosion resistance.
SA387Gr22Cl2 steel plate is mainly used in the manufacture of high-pressure equipment in the fields of petroleum, chemical industry and fertilizer, such as reactors, heat exchangers and separators. In these fields, steel plates need to withstand high temperature, high pressure, corrosion and other harsh environments, so they need to be resistant to high temperature and high pressure and easy to weld and other properties.
