Preston Pipes & Alloys is a distinguished 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, combining high toughness, scaling resistance and phase stability with subsequent aqueous corrosion resistance. Stainless Steel 321H Seamless Pipes have excellent formability and weldability, exceptional toughness, even down to cryogenic temperatures. Stainless Steel 321 Seamless Tubes exhibit oxidation resistance in temperature ranges up to 1500 degrees F, superior creep and stress rupture properties, and good low temperature toughness.

Stainless Steel 321H Seamless Pipes is the modified 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 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 features like strength, 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 work within the temperature range of carbide precipitation 427 to 816 degrees C.

Stainless Steel 321H Seamless Pipes are supplied by us in various industrial application across India these industries include Piston Engine Manifolds, Petrochemical Equipment, Expansion Joints, Breweries, Waste Treatment Plants, Thermal Oxidizers, 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. Stainless Steel 321H Seamless Tubes resists polythionic acid stress corrosion cracking in hydrocarbon service and can be utilized in fluoride-free caustic solutions at mild temperatures.

We at Preston Pipes & Alloys ensure that our clients get only superior quality products and conduct numerous quality tests such as Hardness Testing, Spectro Analysis, Positive Material Identification Testing, and more.
