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

SS 321 Seamless Tubes are used for applications with a temperature range of up to around 900 degrees C, integrating high toughness, scaling resistance and phase stability with resistance to subsequent aqueous corrosion. SS 321H Seamless Pipes have outstanding forming and welding characteristics, exceptional durability, even down to cryogenic temperatures. Stainless Steel 321 Seamless Pipes demonstrate oxidation resistance in temperature ranges up to 1500 degrees F, superior creep and stress rupture properties, and good cryogenic temperature toughness.

Stainless Steel 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 Pipes are used in various applications due to their improved creep resistance and higher strength at temperatures above 1000 degrees F. Our SS 321 Seamless Tubes are well-known for their features like strength, seamless finishing, easy machinability, ready weldability by most standard methods, and dimensional precision and highly demanded across India. Stainless Steel 321H Seamless Tubes are designed to function within the carbide precipitation temperature range 427 to 816 degrees C.

Stainless Steel 321 Seamless Pipes are supplied by us in various industrial application across India these applications include Aerospace Engineering, Petrochemical Equipment, Expansion Joints, Food Processing Equipment, Oil and Gas Refining, Desalination Plants, and Medical Equipment, etc. 321H Stainless Steel 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 per cent diluted solutions at high temperatures. SS 321 Seamless Pipes are immune to polythionic acid stress corrosion cracking in hydrocarbon service and are used in chloride free caustic solutions at moderate temperatures.
