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

SS 321 Seamless Pipes are used for applications in the temperature range of up to about 900 degrees C, combining high toughness, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion. Stainless Steel 321 Seamless Pipes have excellent formability and weldability, exceptional durability, even down to low temperatures. SS 321 Seamless Tubes exhibit oxidation resistance in temperature ranges up to 816 degrees C, higher creep and stress rupture characteristics, 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 strengthened against carbide precipitation. SS 321 Seamless Tubes are used in numerous applications due to their improved creep resistance and higher toughness at temperatures above 537 degrees C. Our Stainless Steel 321 Seamless Pipes are known for their characteristics like durability, 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 321H Seamless Tubes are supplied by us in various industrial application across India these industries include Aerospace Engineering, Petrochemical Equipment, Expansion Joints, Breweries, Waste Treatment Plants, Desalination Plants, and Medical Equipment, etc. 321H Stainless Steel Seamless Pipes can be used in most diluted organic acids at medium temperatures and in pure phosphoric acid at lower temperatures and up to 10 per cent diluted solutions at high temperatures. Stainless Steel 321H Seamless Pipes are immune to polythionic acid stress corrosion cracking in hydrocarbon service and are utilized in chloride free caustic solutions at moderate 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. We also provide various test certificates along with our SS 321H Seamless Pipes including Raw Materials Certificate, 100% Radiography Test Report, Quality Certificates, Third Party Inspection Report.
