Piyush Steel manufactures and supplies stainless steel 321 pipes in Mumbai, India. We provide high-quality stainless steel 321 pipe solutions engineered to meet the stringent requirements of various industrial applications. 321 stainless steel pipe is a titanium-stabilized austenitic stainless steel that offers excellent resistance to intergranular corrosion, especially after exposure to temperatures in the chromium carbide precipitation range of 427-816°C. The typical composition of this alloy includes 17-19% chromium, 9-12% nickel, and a small amount of titanium, which improves the material's ability to withstand extreme conditions. Our pipes are manufactured to ASTM A312 and ASME SA312 standards , ensuring adherence to international quality benchmarks. Additionally, EN 1.4541 Tubing is available for customers seeking DIN-compliant products.
Our 321 stainless steel tubing is an excellent choice for high-temperature environments where resistance to oxidation and scaling is critical. That makes it ideal for applications such as 321 Exhaust Tubing in automotive and aerospace industries, where it can withstand prolonged exposure to high temperatures without compromising performance. As leading 321 stainless steel tube suppliers, we offer seamless and welded options in various finishes and dimensions. Our AISI 321 tubes are particularly popular in industries that require high strength and corrosion resistance, such as chemical processing and petrochemical applications.
We are recognized as one of the top 321 stainless steel tube manufacturers and 321 stainless steel tubing suppliers. Our extensive inventory includes a wide range of stainless steel 321 tube sizes to cater to diverse project requirements, whether you need standard or custom dimensions.
