Sainless steelseamless boiler tubes

Stainless steel seamless boiler tube consists of iron, carbon and other alloying elements, with high hardness, toughness and ductility.


Stainless steel seamless boiler tube is a widely used product in industrial piping industry, which has excellent high temperature, corrosion and pressure resistance properties, and is suitable for a variety of high-pressure, high-temperature and highly corrosive working environment.

The common materials of stainless steel seamless boiler tube are as follows:


304 stainless steel: suitable for general water quality, air, food and beverage and other low corrosive media transportation.

316 stainless steel: suitable for seawater, chemical, paper and other highly corrosive media transportation.

321 stainless steel: suitable for petroleum, fertilizer, nuclear power and other high-temperature media conveying.

347 stainless steel: suitable for oil cracking, ammonia and other high temperature and high pressure media transportation.
