Welded Stainless Steel 321 and 321H pipes form an indispensable part of various industries that require excellent ability to resist corrosion and scalability at high temperatures. Reliable Steel Distributors is among the well-known manufacturers, suppliers, stockists, and exporters of superior-quality welded pipes. Quality has been our prime focus while testing our products for the exacting demands of various industries, ranging from oil and gas, aerospace, and chemical processing to the generation of power.
Stainless Steel 321 is a titanium-added austenitic stainless steel alloy that exhibits outstanding resistance to intergranular corrosion. Hence, the material is ideally suited for applications at elevated temperatures and/or under severe conditions. The addition of titanium reduces the tendency of chromium carbide precipitation upon welding; hence, it improves the toughness of the welded joints. At Reliable Steel Distributors, our 321 welded pipes offer superior performance in challenging workplaces by ensuring compliance with international standards.
321H resistance to high-temperature oxidation is even higher than that for 321, and it has become the choice for high-temperature applications. Increased carbon allows for higher strength in the elevated temperature range in the petrochemical and power industries. Our range of 321H welded pipes is manufactured from superior-quality raw material using the latest manufacturing processes for superior performance. Because we are providers of trust, we keep a complete inventory in order to serve our diverse clients effectively.
