We at Pratik Pipe & Fittings proudly manufacture and supply high-quality Stainless Steel 321 Pipes in Mumbai, India. All our items have been designed with a view to satisfying the high performance and high requirements of many industries with high performance and durability. Stainless Steel 321 is a titanium-stabilized stainless steel with an austenitic structure, famous for its high intergranular corrosion resistance, particularly following long-term service at high temperatures between 427-816°C. With 17-19% chromium, 9-12% nickel, and a minor titanium proportion, the alloy is specifically designed to resist extreme temperatures and environments with no loss of its form. Our pipes comply with ASTM A312 and ASME SA312 specifications, providing international compliance with standards. For customers with a demand for DIN compliance, we have EN 1.4541 pipes for them to opt for.
Our 321 stainless steel tubing is perfect for any application in which high temperature, oxidation protection, and durability are paramount requirements. The automotive, aeronautic, and petrochemical processing industries rely on 321 exhaust tubing for its high-temperature suitability for long-term use with no scaling and loss in performance. With options in both seamless and welded in a variety of finishes and dimensions, at Pratik Pipe & Fittings, we can provide a perfect fit for any use. Require AISI 321 tubing for chemical processing industries, high-strength tubing for industries, and many more?
Being one of the leading 321 stainless steel tubing producers and suppliers, we have an expansive range of stainless steel 321 tubing dimensions in stock, ready for immediate shipping. Quality assurance is our topmost concern, and for that reason, each tubing is checked for compliance with industry standards through thorough testing. Customers looking for SS 321 tubing can rely on competitive pricing, with a price range between ₹450 and ₹700 per kilogram, depending on dimensions, finish, and requirements in terms of quantity. Besides, our tubing is available in a variety of wall thicknesses, supporting a range of operational requirements and ensuring durability and efficiency.
Our SS 321 pipes have a general use in refineries, power generation, and in heat exchangers, wherever high temperature and resistivity towards corrosion is a necessity. In them, titanium prevents carbide precipitation, and hence, these pipes and tubes can function in continuously temperature-changing environments. For any tubing for use in sets of boilers, for parts in furnaces, and in catalytic converters, our SS 321 pipes have an extraordinary performance in harsh environments.
