SS 321H Pipes consist of 17-19% chromium, 9-12% nickel, and a more elevated carbon content (0.04-0.10%) compared to SS 321 for enhanced high-temperature service. These pipes have a tensile strength of about 515 MPa, yield strength of 205 MPa, and elongation of 40%. Their hardness is about 95 HRB. SS 321H physically has a density of 7.9 g/cm³, melting point of 1400°C, and thermal conductivity of 16.3 W/m-K, providing superior heat resistance and mechanical stability in harsh conditions.
Excellent resistance to intergranular corrosion, especially in high-temperature applications. They typically come in sizes ranging from 20 mm to 200 mm on each side, providing robust structural support and versatility for various industries.
Resistance to oxidation and corrosion, SS 321H Seamless Pipes are manufactured without welds or joints, offering uniformity and strength. They are available in 6 mm to 300 mm diameter and are suitable for high-pressure and high-temperature environments.
Good resistance to corrosion and elevated temperatures, Stainless Steel 321H ERW (Electric Resistance Welded) Pipes are produced using electric resistance welding techniques. They are available from 15 mm to 150 mm, ideal for pipelines and structural applications.
SS 321H LSAW (Longitudinal Submerged Arc Welded) Pipes resist high-temperature oxidation and corrosion. These pipes are 60 mm to 1000 mm in diameter and are commonly used in oil and gas transmission and large-diameter piping systems.
Versatile and widely used with strong resistance to scaling and corrosion. They are available in diameters ranging from 10 mm to 500 mm, making them suitable for various industrial applications, including chemical processing.
Excellent resistance to intergranular corrosion, Stainless Steel 321H Welded Pipes are produced by welding and are ideal for applications where joints and fittings are required. They typically come in sizes ranging from 15 mm to 600 mm in diameter, suitable for various structural and mechanical uses.
Stainless Steel 321H Pipes are being applied extensively in the power generation, aerospace, petrochemical, and heat exchanger equipment industries. They are suitable for boiler tubes, furnace parts, exhaust systems, and chemical processing at high temperatures due to their enhanced oxidation resistance. Stainless Steel 321H Pipes are being utilized in pressure vessels, refinery units, and marine environments where aggressive exposure is prevalent. They are highly resistant to thermal fatigue, weldable, and possess high strength, which makes them a top choice for demanding industrial environments.
Weston Stainless offers test certificates, such as Mill Test Certificates (MTC) according to EN 10204 3.1, to guarantee conformity with international quality standards. The pipes are carefully packed in wooden crates, plastic wrapping, or carton boxes to avoid transit damage. With a streamlined supply chain, Weston Stainless guarantees timely and reliable global delivery, meeting urgent industrial needs with precision and care.
