These are the main raw materials which can be made up to high quality carbon construction steel, alloy construction steel and stainless seamless steel especially in the application of high-pressure steaming boilers. To avoid the oxidation and erosion in the hot temperature and super high pressure, it is very necessary to heighten the strength of steel tube, anti-oxidation ability and consistent stability. Carbon construction steel types include the 20G, 20MnG, and 25MnG. Alloy construction steel types include the 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB. Rubiginous heat-resistant steel is ordinarily using types of 1Cr18Ni9 and 1Cr18Ni11Nb. Each seamless steel tube used in high-pressure boiler will take the test of water pressure, pervasion and pushing down accompanied with chemistry component test and mechanic ability test.
