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 Pipes are used for applications in the temperature range of up to about 900 degrees C, integrating high toughness, scaling resistance and phase stability with resistance to subsequent aqueous corrosion. SS 321 Seamless Tubes have outstanding formability and weldability, superior durability, even down to low temperatures. SS 321 Seamless Tubes demonstrate oxidation resistance in temperature ranges up to 1500 degrees F, higher creep and stress rupture properties, and good low temperature strength.

SS 321H Seamless Pipes is the improved high carbon version of Stainless Steel 321 a general purpose austenitic SS that is stabilized against carbide precipitation. SS 321 Seamless Tubes are used in various applications owing to their enhanced creep resistance and higher toughness at temperatures above 1000 degrees F. Our SS 321 Seamless Pipes are well-known for their characteristics like durability, rugged construction, easy formability, ready weldability by most standard methods, and dimensional precision and highly demanded across India. Stainless Steel 321H Seamless Pipes are designed to function within the temperature range of carbide precipitation 800 to 1500 degrees F.

SS 321H Seamless Pipes are supplied by us in various industrial application across India these applications include Piston Engine Manifolds, Petrochemical Equipment, Expansion Joints, Food Processing Equipment, Waste Treatment Plants, Desalination Plants, and Pharmaceutical Production, etc. 321 Stainless Steel Seamless Tubes are used in most diluted organic acids at medium temperatures and in pure phosphoric acid at cycrogenic temperatures and up to 10 per cent diluted solutions at elevated temperatures. SS 321 Seamless Pipes 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 make sure that our clients get only high quality pipes and tubes 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 Stainless Steel 321H Seamless Pipes including Raw Materials Certificate, 100 per cent Radiography Test Report, Quality Certificates, Third Party Inspection Report. We export these SS 321H Seamless Pipes to various regions across India.
