Manufacturers of UNS S31500 (321H) Stainless Steel Welded Tubes designed for high-temperature applications, offering enhanced strength, excellent resistance to intergranular corrosion, and reliable performance in thermal and oxidizing environments.
Our UNS S31500 Stainless Steel Welded Tubes are engineered
for superior performance in demanding industrial environments. This duplex
stainless steel grade offers an excellent balance of high mechanical
strength and corrosion resistance, making it suitable for chemical
processing, marine, and pulp & paper applications.
These tubes provide outstanding resistance to stress corrosion cracking,
pitting, and crevice corrosion, especially in chloride-rich conditions.
The duplex microstructure enhances durability, while welded construction
ensures dimensional uniformity, reliability, and cost efficiency. A smooth
surface finish further improves resistance to oxidation and scaling.
Available in a wide range of sizes and customizable specifications, UNS
S31500 stainless steel welded tubes deliver long-lasting performance and
reliability for industries that demand strength, corrosion resistance,
and consistent quality.
Our pipes and tubes are widely supplied across India and the Middle East, serving industries such as oil & gas, water treatment, power generation, and infrastructure. Countries including Saudi Arabia, UAE, Qatar, Oman, Kuwait, and Bahrain rely on our products for consistent quality and reliable performance.
