Possible Alternative Grades
- For stainless steel boiler tube intended for marine and chemical processing equipment, Duplex stainless steels such as UNS S31803 and UNS S32205 are recommended, as they offer excellent resistance to chloride stress corrosion cracking.
- Ferritic grades-such as AISI 444, 430, and 439-are cost-effective options suitable for use in boiler tubes operating at moderate to low temperatures, heat exchanger tubes, and flue gas treatment systems.
- For applications requiring high-temperature resistance, grades such as TP321H, TP348, and TP348H are ideal choices; these materials exhibit superior resistance to intergranular corrosion and are well-suited for long-term service in high-temperature environments.
application areas
Subjected to rigorous quality control, our tubing is primarily utilized in applications requiring resistance to high temperatures and high pressures-such as power plant boilers, petrochemical facilities, and reheaters.
