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

Stainless Steel 321 Seamless Pipes are utilized 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. Stainless Steel 321 Seamless Pipes have excellent formability and weldability, superior durability, even down to low temperatures. Stainless Steel 321 Seamless Pipes exhibit resistance to oxidation in temperature ranges up to 1500 degrees F, higher creep and stress rupture characteristics, and good low temperature strength.

SS 321H Seamless Pipes is the modified high carbon version of Stainless Steel 321 a general purpose austenitic SS that is stabilized against carbide precipitation. SS 321 Seamless Tubes are used in various applications due to their enhanced creep resistance and superior toughness at temperatures above 537 degrees C. Our SS 321 Seamless Pipes are known for their characteristics like strength, seamless finishing, easy formability, ready weldability by most standard processes, and dimensional precision and highly demanded across India. SS 321H Seamless Tubes are designed to work 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 Aerospace Engineering, Petrochemical Equipment, Petroleum Industry, Breweries, Waste Treatment Plants, Thermal Oxidizers, and Medical Equipment, etc. 321H Stainless Steel Seamless Pipes can be utilized 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. Stainless Steel 321 Seamless Tubes resists polythionic acid stress corrosion cracking in hydrocarbon service and can be utilized in chloride free caustic solutions at moderate temperatures.
