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

SS 321 Seamless Tubes are utilized for applications with a temperature range of up to around 900 degrees C, integrating high toughness, scaling resistance and phase stability with subsequent aqueous corrosion resistance. Stainless Steel 321 Seamless Tubes have outstanding forming and welding characteristics, superior durability, even down to cryogenic temperatures. Stainless Steel 321 Seamless Tubes demonstrate oxidation resistance in temperature ranges up to 816 degrees C, superior creep and stress rupture characteristics, and good low temperature strength.

Stainless Steel 321H Seamless Pipes is the modified high carbon version of SS 321 a general purpose austenitic Stainless Steel that is stabilized against carbide precipitation. SS 321 Seamless Tubes are used in numerous applications owing to their enhanced creep resistance and superior strength at temperatures above 1000 degrees F. Our Stainless Steel 321H Seamless Tubes are known for their characteristics like strength, rugged construction, easy machinability, ready weldability by most standard processes, and dimensional accuracy and highly demanded across India. SS 321H Seamless Tubes are designed to function within the carbide precipitation temperature range 427 to 816 degrees C.

SS 321 Seamless Tubes are supplied by us in various industrial application across India these industries include Aerospace Engineering, Petrochemical Equipment, Expansion Joints, Breweries, Waste Treatment Plants, Desalination Plants, and Pharmaceutical Production, etc. 321 SS Seamless Pipes are utilized 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 321H Seamless Pipes are immune to polythionic acid stress corrosion cracking in hydrocarbon service and can be used in chloride free caustic solutions at mild temperatures.
