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

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

Stainless Steel 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 Pipes are used in numerous applications owing to their improved creep resistance and higher strength at temperatures above 1000 degrees F. Our Stainless Steel 321H Seamless Pipes 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 carbide precipitation temperature range 800 to 1500 degrees F.

Stainless Steel 321H Seamless Tubes are supplied by us in various industrial application across India these industries include Aerospace Engineering, Petrochemical Equipment, Expansion Joints, Food Processing Equipment, Waste Treatment Plants, Thermal Oxidizers, and Medical Equipment, etc. 321 SS Seamless Tubes are used in most diluted organic acids at moderate temperatures and in pure phosphoric acid at cycrogenic temperatures and up to 10 per cent diluted solutions at elevated temperatures. Stainless Steel 321 Seamless Tubes resists polythionic acid stress corrosion cracking in hydrocarbon service and can be used in fluoride-free caustic solutions at moderate temperatures.

We at Preston Pipes & Alloys ensure that our clients get only superior quality pipes and tubes and undertake numerous quality tests such as Mechanical Testing, Chemical Analysis, Positive Material Identification Testing, and more. We also provide various test certificates along with our Stainless Steel 321H Seamless Pipes including Raw Materials Certificate, 100% Radiography Test Report, Quality Certificates, Third Party Inspection Report.
