Manufacturers of 321H Stainless Steel Welded Tubes designed for high-temperature applications, offering enhanced carbon content for improved strength, excellent resistance to intergranular corrosion, and reliable performance in oxidizing and thermal environments.
Our 321H Stainless Steel Welded Tubes are specifically
designed for high-temperature and high-pressure applications that demand
exceptional mechanical strength and long-term reliability. With a higher
carbon content compared to standard 321 grade, 321H stainless steel
provides improved strength and creep resistance at elevated temperatures,
making it ideal for severe service conditions.
Titanium stabilization enhances resistance to intergranular corrosion,
particularly after welding, while excellent oxidation and scaling
resistance ensures durability in aggressive thermal environments. The
welded construction delivers consistent strength, dimensional accuracy,
and structural uniformity, while the smooth internal and external surface
finish contributes to improved corrosion resistance and service life.
Commonly used in power plants, petrochemical refineries, heat exchangers,
pressure vessels, and high-temperature processing systems, our 321H
stainless steel welded tubes provide a dependable and cost-effective
solution for critical industrial applications. Available in a wide range
of sizes and customizable specifications, they are engineered to perform
reliably under extreme operating conditions.

Increased carbon content enhances tensile strength and creep resistance, making 321H ideal for high-temperature and high-pressure applications.
Titanium stabilization prevents carbide precipitation during welding and elevated temperature exposure, ensuring excellent resistance to intergranular corrosion.
Maintains mechanical integrity, oxidation resistance, and dimensional stability under prolonged thermal exposure.
Manufactured using advanced welding processes to achieve strong weld seams, precise dimensions, and consistent structural reliability.
Smooth internal and external surface finish improves resistance to oxidation, scaling, and corrosion in high-temperature service.
Widely used in power plants, heat exchangers, pressure vessels, petrochemical refineries, and other severe service environments.
321H Stainless Steel Welded Tubes are manufactured using premium chromium-nickel stainless steel stabilized with titanium and higher carbon content for enhanced high-temperature strength. Advanced forming and welding technologies ensure uniform wall thickness, excellent weld integrity, precise dimensional accuracy, and reliable performance in severe thermal and pressure environments.
Each 321H stainless steel welded tube undergoes rigorous quality inspections including weld seam examination, Eddy Current Testing (ECT), dimensional verification, Positive Material Identification (PMI), and detailed visual inspection to ensure resistance to oxidation, scaling, intergranular corrosion, and long-term service reliability at elevated temperatures.
Our 321H Stainless Steel Welded Tubes are manufactured in compliance with ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and applicable ASTM, EN, and international standards, ensuring consistent quality, safety, and performance for power plants, heat exchangers, petrochemical units, refineries, and other high-temperature industrial applications.
