347 Stainless Steel Pipes Supplier and Exporter | UNS S34700, SUS 347 & DIN 1.4550 | Leoscor Alloy Pipes
347 Stainless Steel Pipes are niobium-stabilized austenitic stainless steel pipes designed for high-temperature applications requiring excellent strength, corrosion resistance, and long-term reliability.
Leoscor Alloy Pipes is a trusted manufacturer, stockist, supplier, and exporter of SS 347 Pipes, offering high-quality piping solutions in different sizes, wall thicknesses, schedules, and customized specifications according to industrial requirements.
SS 347 Pipes are stabilized austenitic stainless steel pipes containing niobium as an alloying element. The addition of niobium helps prevent carbide precipitation during welding and high-temperature exposure, improving resistance against intergranular corrosion.
These pipes maintain good mechanical strength, oxidation resistance, and corrosion resistance during prolonged service at elevated temperatures. Due to their stability after welding, 347 Stainless Steel Pipes are widely used in demanding thermal and industrial applications.
The grade is internationally identified through different material designations including UNS S34700 Stainless Steel Pipes, SUS 347 Stainless Steel Pipes, and DIN 1.4550 Stainless Steel Pipes.
Leoscor Alloy Pipes supplies premium-quality Stainless Steel Pipes including 347 Stainless Steel Pipes with customized dimensions, inspection documents, and technical support. Contact us today to discuss your requirements and get a competitive quotation.
