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

SS 321 Seamless Tubes are used for applications in the temperature range of up to about 900 degrees C, combining high toughness, scaling resistance and phase stability with resistance to subsequent aqueous corrosion. Stainless Steel 321H Seamless Pipes have excellent forming and welding characteristics, exceptional durability, even down to low temperatures. SS 321 Seamless Pipes exhibit oxidation resistance in temperature ranges up to 1500 degrees F, higher creep and stress rupture characteristics, and good cryogenic temperature toughness.

SS 321H Seamless Pipes is the improved high carbon version of Stainless Steel 321 a general purpose austenitic Stainless Steel that is strengthened against carbide precipitation. SS 321 Seamless Pipes are used in numerous applications owing to their improved creep resistance and higher toughness at temperatures above 537 degrees C. Our Stainless Steel 321 Seamless Pipes are known for their features like durability, seamless finishing, easy machinability, ready weldability by most standard processes, and dimensional accuracy and highly demanded across India. Stainless Steel 321H Seamless Pipes are developed to function within the temperature range of carbide precipitation 800 to 1500 degrees F.

SS 321 Seamless Tubes are supplied by us in various industrial application across India these applications include Aerospace Engineering, Chemical Processing Equipment, Petroleum Industry, Breweries, Waste Treatment Plants, Desalination Plants, and Pharmaceutical Production, etc. 321H Stainless Steel Seamless Tubes can be used in most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and up to 10 per cent diluted solutions at elevated temperatures. SS 321 Seamless Tubes resists polythionic acid stress corrosion cracking in hydrocarbon service and can be 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 tests such as Hardness Testing, Spectro Analysis, PMI Testing, and more. We also provide numerous test certificates along with our SS 321 Seamless Tubes including Raw Materials Certificate, 100% Radiography Test Report, Quality Certificates, Third Party Inspection Report. We export these SS 321H Seamless Pipes to various regions across India.
