The material of boiler steel tube depends on your application environment and temperature.

In case of low and medium pressure environment, low and medium pressure boiler steel tube is used. The executive standard of low and medium pressure boiler tube is GB / T3087, etc.. The working pressure is generally not greater than 5.88 MPA, and the working temperature is below 450℃. It is used to manufacture all kinds of low and medium pressure boilers, superheated steam tubes, boiling water tubes, water wall tubes, superheated steam tubes, large smoke tubes, small smoke tubes and arch brick tubes for locomotive boilers. The main low and medium pressure boiler steel tube materials are 20#, Q345B, etc.

The executive standard of high pressure boiler steel tube is GB / T5310, etc.. The working pressure is generally above 9.8 MPa, and the working temperature is between 450℃ and 650℃. High pressure boiler steel tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts and main steam tubes of high-pressure and ultra-high-pressure boilers. The main high pressure boiler steel tube materials are: 20G, 20MnG, 25MnG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, 12Cr2MoWVTiB, 10Cr9Mo1VNbN, SA210A1, SA210C, A213 T11, A213 T12, A213 T22, A213 T23, SA213 T91, SA213 T92, ST45.8, 15Mo3, 13CrMo44, 10CrMo910, etc.
