JIS G3462 alloy steel boiler tubes are mainly used for heat exchangers inside and outside boilers, such as boiler water tubes, smoke tubes, superheater tubes, air preheater tubes, etc.
There are many different alloy steel grades under the JIS G3462 boiler tube standard, such as STBA22, STBA23, STBA24, STBA26, etc. It has high lasting strength, good oxidation corrosion resistance and structural stability, and is very suitable for working under high temperature and high pressure conditions. It is usually suitable for pipes with an outer diameter between 15.9 mm and 139.8 mm.
