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

Stainless Steel 321 Seamless Pipes are used for applications with a temperature range of up to around 900 degrees C, integrating high strength, scaling resistance and phase stability with subsequent aqueous corrosion resistance. SS 321H Seamless Pipes have outstanding formability and weldability, superior durability, even down to low temperatures. SS 321 Seamless Tubes demonstrate resistance to oxidation in temperature ranges up to 816 degrees C, higher creep and stress rupture properties, and good low temperature strength.

Stainless Steel 321H Seamless Tubes is the improved high carbon version of Stainless Steel 321 a general purpose austenitic SS that is stabilized against carbide precipitation. Stainless Steel 321 Seamless Pipes are used in various applications due to their improved creep resistance and superior toughness at temperatures above 537 degrees C. Our Stainless Steel 321 Seamless Tubes are well-known for their features like durability, rugged construction, easy machinability, ready weldability by most standard methods, and dimensional precision and highly demanded across India. SS 321H Seamless Pipes are developed to function within the temperature range of carbide precipitation 427 to 816 degrees C.

Stainless Steel 321H Seamless Tubes are supplied by us in various industrial application across India these applications include Piston Engine Manifolds, Petrochemical Equipment, Petroleum Industry, Food Processing Equipment, Oil and Gas Refining, Desalination Plants, and Pharmaceutical Production, etc. 321H 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% diluted solutions at elevated temperatures. SS 321H Seamless Pipes are immune to polythionic acid stress corrosion cracking in hydrocarbon service and are utilized in fluoride-free caustic solutions at mild temperatures.

We at Preston Pipes & Alloys make sure that our consumers get only high quality pipes and tubes and conduct numerous quality tests such as Mechanical Testing, Spectro Analysis, PMI Testing, and so on.
