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 utilized for applications in the temperature range of up to about 900 degrees C, combining high toughness, scaling resistance and phase stability with resistance to subsequent aqueous corrosion. Stainless Steel 321H Seamless Pipes have outstanding formability and weldability, exceptional toughness, even down to low temperatures. Stainless Steel 321 Seamless Tubes demonstrate resistance to oxidation in temperature ranges up to 1500 degrees F, higher creep and stress rupture characteristics, and good cryogenic temperature toughness.

Stainless Steel 321H Seamless Tubes 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 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. SS 321H Seamless Pipes are designed 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 industries include Piston Engine Manifolds, Chemical Processing Equipment, Expansion Joints, Breweries, Waste Treatment Plants, Desalination Plants, and Medical Equipment, etc. 321H SS Seamless Pipes can be used in most diluted organic acids at moderate temperatures and in pure phosphoric acid at cycrogenic temperatures and up to 10% diluted solutions at elevated temperatures. SS 321H Seamless Pipes are immune to polythionic acid stress corrosion cracking in hydrocarbon service and can be utilized in fluoride-free caustic solutions at moderate temperatures.

We at Preston Pipes & Alloys ensure that our consumers get only superior quality products and undertake numerous quality checks such as Mechanical Testing, Chemical Analysis, Positive Material Identification Testing, and more. We also provide numerous test certificates along with our Stainless Steel 321 Seamless Pipes including Raw Materials Certificate, 100 per cent Radiography Test Report, Quality Certificates, Third Party Inspection Report.
