Preston Pipes & Alloys is a notable manufacturer, stockist 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, combining high strength, scaling resistance and phase stability with resistance to subsequent aqueous corrosion. SS 321H Seamless Pipes have excellent formability and weldability, superior toughness, even down to cryogenic temperatures. SS 321 Seamless Tubes demonstrate resistance to oxidation in temperature ranges up to 816 degrees C, superior creep and stress rupture properties, and good cryogenic temperature toughness.

Stainless Steel 321H Seamless Tubes is the improved high carbon version of Stainless Steel 321 a general purpose austenitic SS that is strengthened against carbide precipitation. Stainless Steel 321 Seamless Tubes are used in numerous applications due to their enhanced creep resistance and superior strength at temperatures above 537 degrees C. Our SS 321H Seamless Tubes are known for their features like durability, seamless finishing, easy formability, ready weldability by most standard processes, and dimensional precision and highly demanded across India. SS 321H Seamless Tubes are developed to work within the carbide precipitation temperature range 427 to 816 degrees C.

SS 321 Seamless Pipes are supplied by us in various industrial application across India these industries include Piston Engine Manifolds, Chemical Processing Equipment, Expansion Joints, Food Processing Equipment, Waste Treatment Plants, Desalination Plants, and Medical Equipment, etc. 321H SS Seamless Tubes are used in most diluted organic acids at medium temperatures and in pure phosphoric acid at lower temperatures and up to 10 per cent diluted solutions at high temperatures. Stainless Steel 321 Seamless Pipes resists 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 clients get only superior quality products and conduct numerous quality tests such as Hardness Testing, Chemical Analysis, PMI Testing, and so on. We also provide various test certificates along with our SS 321 Seamless Tubes including Manufacturer Test Certificate according to EN 10204/3.1B, 100 per cent Radiography Test Report, Quality Certificates, Third Party Inspection Report.
