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

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

SS 321H Seamless Pipes is the improved high carbon version of Stainless Steel 321 a general purpose austenitic SS that is stabilized against carbide precipitation. SS 321 Seamless Tubes are used in various applications owing to their improved creep resistance and superior strength at temperatures above 537 degrees C. Our SS 321 Seamless Tubes are well-known for their characteristics like strength, seamless finishing, easy formability, ready weldability by most standard processes, and dimensional accuracy and highly demanded across India. Stainless Steel 321H Seamless Pipes are developed to function within the carbide precipitation temperature range 427 to 816 degrees C.

Stainless Steel 321H Seamless Tubes are supplied by us in various industrial application across India these applications include Piston Engine Manifolds, Chemical Processing Equipment, Petroleum Industry, Food Processing Equipment, Oil and Gas Refining, Desalination Plants, and Medical Equipment, etc. 321 Stainless Steel Seamless Pipes are 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 321H Seamless Tubes are immune to polythionic acid stress corrosion cracking in hydrocarbon service and are utilized in fluoride-free caustic solutions at moderate temperatures.

We at Preston Pipes & Alloys make sure that our consumers get only high quality pipes and tubes and undertake various quality tests such as Hardness Testing, Chemical Analysis, PMI Testing, and more. We also provide various test certificates along with our SS 321 Seamless Tubes including Raw Materials Certificate, 100 per cent Radiography Test Report, Quality Certificates, Third Party Inspection Report.
