JIS G3458 STPA22 alloy steel tube has excellent high temperature resistance, low temperature resistance, and corrosion resistance.
It is suitable for high temperature, high pressure and certain corrosion working environment, such as power equipment, petrochemical, power and other industries.
JIS G3458 STPA22 Seamless alloy boiler tube has good high temperature mechanical properties, and has high endurance strength and creep resistance in the temperature range of 300~400℃. Its maximum working temperature can reach 540℃, but when the temperature exceeds 550℃, the creep limit will drop significantly.
