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

Stainless Steel 321 Seamless Tubes are used for applications in the temperature range of up to about 900 degrees C, integrating high strength, scaling resistance and phase stability with subsequent aqueous corrosion resistance. SS 321 Seamless Tubes have excellent forming and welding characteristics, superior toughness, even down to cryogenic temperatures. SS 321 Seamless Tubes exhibit resistance to oxidation in temperature ranges up to 816 degrees C, superior creep and stress rupture properties, and good cryogenic temperature strength.

SS 321H Seamless Pipes is the improved high carbon version of SS 321 a general purpose austenitic SS that is stabilized against carbide precipitation. Stainless Steel 321 Seamless Tubes are used in various applications due to their enhanced creep resistance and superior strength at temperatures above 1000 degrees F. Our SS 321H Seamless Tubes are known for their characteristics like strength, seamless finishing, easy machinability, ready weldability by most standard methods, and dimensional accuracy and highly demanded across India. SS 321H Seamless Pipes are developed to work within the temperature range of carbide precipitation 800 to 1500 degrees F.

SS 321 Seamless Pipes are supplied by us in various industrial application across India these applications include Aerospace Engineering, Petrochemical Equipment, Petroleum Industry, Food Processing Equipment, Oil and Gas Refining, Desalination Plants, and Pharmaceutical Production, etc. 321 SS Seamless Pipes can be used in most diluted organic acids at moderate temperatures and in pure phosphoric acid at cycrogenic temperatures and up to 10% diluted solutions at elevated temperatures. Stainless Steel 321 Seamless Pipes resists polythionic acid stress corrosion cracking in hydrocarbon service and are utilized in fluoride-free caustic solutions at moderate temperatures.

We at Preston Pipes & Alloys ensure that our consumers get only high quality products and undertake various quality tests such as Mechanical Testing, Chemical Analysis, PMI Testing, and so on. We also provide various test certificates along with our SS 321H Seamless Pipes including Raw Materials Certificate, 100 per cent Radiography Test Report, Quality Certificates, Third Party Inspection Report.
