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

Stainless Steel 321 Seamless Pipes are used for applications in the temperature range of up to about 900 degrees C, combining high strength, resistance to scaling and phase stability with subsequent aqueous corrosion resistance. SS 321H Seamless Tubes have outstanding formability and weldability, exceptional toughness, even down to cryogenic temperatures. Stainless Steel 321 Seamless Pipes exhibit oxidation resistance in temperature ranges up to 816 degrees C, higher creep and stress rupture properties, and good cryogenic temperature strength.

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

SS 321 Seamless Tubes are supplied by us in various industrial application across India these applications include Piston Engine Manifolds, Petrochemical Equipment, Petroleum Industry, Breweries, Oil and Gas Refining, Thermal Oxidizers, and Pharmaceutical Production, etc. 321 SS Seamless Pipes are utilized in most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and up to 10% diluted solutions at elevated temperatures. SS 321H Seamless Pipes resists polythionic acid stress corrosion cracking in hydrocarbon service and are used in fluoride-free caustic solutions at moderate temperatures.

We at Preston Pipes & Alloys make sure that our clients get only high quality products and conduct numerous quality tests such as Hardness Testing, Spectro Analysis, Positive Material Identification Testing, and more. We also provide various test certificates along with our SS 321H Seamless Tubes including Manufacturer Test Certificate according to EN 10204/3.1B, 100 per cent Radiography Test Report, Quality Certificates, Third Party Inspection Report.
