W. Nr. 1.4541 Welded Pipe, AISI 321H Boiler & Heat Exhanger Tubes Manufacturer

321 is an austenitic alloy made with chromium and nickel in its composition. The Stainless Steel 321 Pipe is an ideal choice for applications, which are up to 900 degrees C. These pipes are highly resistant to corrosion and sterilizing agents. The Stainless Steel 321 Tube is designed with high resistance to intergranular corrosion. They are commonly used in exhausts, aircraft collector rings, and high-temperature chemical equipment. We are one of the top Stainless Steel 321 Pipe, manufacturers in India who focus on creating high-quality products at the most reasonable prices. We are the only 321 Stainless Steel Tubing suppliers who provide our clients with customized products within a short time frame.

The SS 321 Seamless Pipe is produced from a single billet.. To give it desirable properties, it is cold-rolled after it gets cooled after hot-rolling. 321 SS Welded Pipe contains titanium which is  at least 5 times that of carbon content. It is formed after joining the seams longitudinally. The ASTM A312 TP 321 Round Pipe has a welded seam in its interior to give it the right shape. Our skilled workers following national and international standards manufacture the Cres 321 Tubing.

The 321 Exhaust Tubing is highly durable and strong. These tubings are easy to bend and weld and can easily handle a lot of heat. The 321 UNS S32100 ERW Pipe is a versatile pipe, which is, formed after cold-rolling it. They are used to resist high and low frequencies in may applications. We are amongst a few 321 Tubing suppliers who make use of the latest technology and best raw materials while producing all our products.
