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 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 subsequent aqueous corrosion resistance. SS 321 Seamless Tubes have excellent formability and weldability, exceptional toughness, even down to low temperatures. SS 321 Seamless Tubes exhibit resistance to oxidation in temperature ranges up to 1500 degrees F, superior creep and stress rupture properties, and good low temperature strength.

Stainless Steel 321H Seamless Pipes is the improved high carbon version of Stainless Steel 321 a general purpose austenitic Stainless Steel that is stabilized against carbide precipitation. Stainless Steel 321 Seamless Tubes are used in numerous applications owing to their improved creep resistance and superior toughness at temperatures above 537 degrees C. Our Stainless Steel 321H Seamless Tubes are known for their characteristics 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 designed to function within the temperature range of carbide precipitation 427 to 816 degrees C.

SS 321H Seamless Pipes are supplied by us in various industrial application across India these applications include Piston Engine Manifolds, Petrochemical Equipment, Expansion Joints, Food Processing Equipment, Oil and Gas Refining, Thermal Oxidizers, and Pharmaceutical Production, etc. 321 Stainless Steel Seamless Pipes are 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 elevated temperatures. SS 321H Seamless Tubes are immune to polythionic acid stress corrosion cracking in hydrocarbon service and are used in chloride free caustic solutions at mild temperatures.

We at Preston Pipes & Alloys make sure that our consumers get only high quality products and conduct numerous quality checks such as Mechanical Testing, Chemical Analysis, PMI Testing, and more.
