Preston Pipes & Alloys is a distinguished manufacturer, distributor and exporter of Stainless Steel 321/321H Seamless Pipes/Tubes in Mumbai, India.

Stainless Steel 321 Seamless Tubes are utilized for applications with a temperature range of up to around 900 degrees C, integrating high strength, resistance to scaling and phase stability with subsequent aqueous corrosion resistance. SS 321 Seamless Tubes have excellent formability and weldability, superior toughness, even down to low temperatures. Stainless Steel 321 Seamless Pipes exhibit resistance to oxidation in temperature ranges up to 1500 degrees F, superior creep and stress rupture characteristics, and good cryogenic temperature toughness.

Stainless Steel 321H Seamless Pipes is the modified high carbon version of Stainless Steel 321 a general purpose austenitic Stainless Steel that is strengthened against carbide precipitation. SS 321 Seamless Pipes are used in various applications due to their enhanced creep resistance and superior strength at temperatures above 537 degrees C. Our SS 321 Seamless Tubes are well-known for their characteristics like durability, rugged construction, easy formability, ready weldability by most standard methods, and dimensional precision and highly demanded across India. SS 321H Seamless Pipes are designed to work within the carbide precipitation temperature range 800 to 1500 degrees F.

Stainless Steel 321H Seamless Pipes are supplied by us in various industrial application across India these industries include Aerospace Engineering, Chemical Processing Equipment, Petroleum Industry, Food Processing Equipment, Waste Treatment Plants, Thermal Oxidizers, and Pharmaceutical Production, etc. 321 SS Seamless Tubes can be used in most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and up to 10 per cent diluted solutions at elevated temperatures. SS 321 Seamless Tubes are immune to polythionic acid stress corrosion cracking in hydrocarbon service and are used in chloride free caustic solutions at moderate temperatures.

We at Preston Pipes & Alloys ensure that our consumers get only high quality pipes and tubes and conduct numerous quality tests such as Hardness Testing, Spectro Analysis, PMI Testing, and more. We also provide numerous test certificates along with our SS 321 Seamless Tubes including Raw Materials Certificate, 100% Radiography Test Report, Quality Certificates, Third Party Inspection Report. We export these SS 321 Seamless Pipes to various cities across India.
