Equivalent Grades Table for GB5310 Boiler Tubes

This paper mainly introduces the characteristics of GB5310 high pressure seamless steel pipe and its equivalent high pressure boiler tube material (steel grade) in the world
GB5310 steel tubes are mainly used to manufacture high-pressure steam boiler pipes and other high-quality carbon structures.

Seamless steel tubes for GB5310 high pressure boilers often work under high temperature and pressure, and the tubes will also be oxidized and corroded under the action of high temperature flue gas and steam. Therefore, it is required that the steel tubes have high endurance strength, high oxidation resistance and good structural stability.

At present, the common standards of seamless steel tubes for high-pressure boilers in China are GB 5310. ASME sa106, ASME SA209, ASME SA210, ASME SA213, ASME SA335, American standards.JIS b8230, JIS b8241, Japan standards. DIN 17200, DIN 2448, German standard. ГОСТ4543、ГОСТ8731,Russian standards, etc.

At present, the international steel high-pressure boiler has been widely used in petrochemical, machinery, metallurgy, energy, light industry, national defense, environmental protection, marine, space, life and other industrial sectors and scientific research fields, with the specification of Φ 10 ~ 1064mm and above. Many specification enterprises have the production capacity of high-pressure boiler pipe, and they also use a wide range of steel, including high-quality carbon steel 20g, manganese steel SA-106C, SA-210C, molybdenum steel 15Mo3 Sa-209 t1a, chrome molybdenum steel sa-213 t2, 15CrMoG, sa-213 t22, chrome molybdenum vanadium steel 12Cr1MoVG, 12Cr2MoWVTiB (steel 102), sa-213 t91, chrome nickel steel SA-213 tp304h, SA-213 tp347h, etc.
