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

Stainless Steel 321 Seamless Tubes are used for applications with a temperature range of up to around 900 degrees C, combining high strength, resistance to scaling and phase stability with subsequent aqueous corrosion resistance. SS 321 Seamless Tubes have excellent formability and weldability, exceptional durability, even down to cryogenic temperatures. Stainless Steel 321 Seamless Tubes exhibit 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 Pipes is the modified high carbon version of SS 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 toughness at temperatures above 1000 degrees F. Our Stainless Steel 321 Seamless Pipes are well-known for their features like durability, rugged construction, easy formability, ready weldability by most standard methods, 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 321H Seamless Pipes are supplied by us in various industrial application across India these industries include Piston Engine Manifolds, Petrochemical Equipment, Expansion Joints, Food Processing Equipment, Waste Treatment Plants, Desalination Plants, and Medical Equipment, etc. 321H 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% diluted solutions at elevated temperatures. Stainless Steel 321 Seamless Pipes resists polythionic acid stress corrosion cracking in hydrocarbon service and can be used in chloride free caustic solutions at mild temperatures.
