GB8163 steel can be used as a general seamless transport liquid gas it can be widely used in the manufacture of structural and mechanical parts, high flexural strength of objects, GB8163 steel concrete manufacturing methods. The temperature of the boiler tubes generally used in the following 450 degrees, so that it can properly use, GB8163 steel tube manufacturing is also divided into hot and cold. When using high-pressure boiler will often be in a high temperature and pressure conditions, high temperature flue gas and water vapor in that the pipe under the role of chemical reactions occur, such as oxidation and corrosion, steel will have a high rupture strength, will have high corrosion resistance, there will be a high good organizational stability. Is generally used to manufacture products for the dedicated, high-pressure boiler tube is mainly used to manufacture high and ultra-high pressure boiler superheater tubes, reheater tube, airway, the main steam pipe.
