Preston Pipes & Alloys is a notable manufacturer, stockist 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 strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion. SS 321 Seamless Tubes have excellent forming and welding characteristics, superior toughness, even down to cryogenic temperatures. Stainless Steel 321 Seamless Tubes exhibit resistance to oxidation in temperature ranges up to 1500 degrees F, higher creep and stress rupture properties, and good cryogenic temperature strength.

SS 321H Seamless Tubes is the modified high carbon version of Stainless Steel 321 a general purpose austenitic SS that is strengthened against carbide precipitation. SS 321 Seamless Tubes are used in various applications owing to their enhanced creep resistance and superior strength at temperatures above 1000 degrees F. Our SS 321 Seamless Pipes are well-known for their features like durability, seamless finishing, easy formability, ready weldability by most standard processes, and dimensional accuracy and highly demanded across India. Stainless Steel 321H Seamless Tubes are designed to function within the carbide precipitation temperature range 800 to 1500 degrees F.

Stainless Steel 321 Seamless Tubes are supplied by us in various industrial application across India these applications include Aerospace Engineering, Petrochemical Equipment, Petroleum Industry, Breweries, Waste Treatment Plants, Desalination Plants, and Pharmaceutical Production, etc. 321H SS Seamless Tubes 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. SS 321H 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 clients get only high quality products and conduct various quality tests such as Mechanical Testing, Spectro Analysis, Positive Material Identification Testing, and more. We also provide various test certificates along with our SS 321H Seamless Tubes including Manufacturer Test Certificate according to EN 10204/3.1B, 100% Radiography Test Report, Quality Certificates, Third Party Inspection Report.
