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 in the temperature range of up to about 900 degrees C, combining high toughness, resistance to scaling and phase stability with subsequent aqueous corrosion resistance. SS 321 Seamless Tubes have excellent forming and welding characteristics, superior durability, even down to cryogenic temperatures. SS 321 Seamless Tubes exhibit resistance to oxidation in temperature ranges up to 816 degrees C, higher creep and stress rupture characteristics, and good low temperature toughness.

SS 321H Seamless Pipes is the modified high carbon version of Stainless Steel 321 a general purpose austenitic Stainless Steel that is strengthened against carbide precipitation. Stainless Steel 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, rugged construction, easy formability, ready weldability by most standard methods, and dimensional accuracy and highly demanded across India. SS 321H Seamless Pipes are developed to function within the temperature range of carbide precipitation 800 to 1500 degrees F.

Stainless Steel 321H Seamless Pipes are supplied by us in various industrial application across India these applications include Piston Engine Manifolds, Chemical Processing Equipment, Expansion Joints, Breweries, Oil and Gas Refining, Thermal Oxidizers, and Medical Equipment, etc. 321H 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 high temperatures. Stainless Steel 321 Seamless Pipes resists polythionic acid stress corrosion cracking in hydrocarbon service and are utilized in chloride free caustic solutions at mild temperatures.

We at Preston Pipes & Alloys make sure that our consumers get only high quality products and conduct numerous quality checks such as Mechanical Testing, Spectro Analysis, Positive Material Identification Testing, and so on. 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. We export these Stainless Steel 321H Seamless Tubes to various cities across India.
