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

SS 321 Seamless Pipes are utilized for applications with a temperature range of up to around 900 degrees C, integrating high toughness, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion. Stainless Steel 321H Seamless Pipes have outstanding forming and welding characteristics, exceptional toughness, even down to cryogenic temperatures. Stainless Steel 321 Seamless Pipes exhibit resistance to oxidation in temperature ranges up to 1500 degrees F, higher creep and stress rupture characteristics, and good low temperature toughness.

Stainless Steel 321H Seamless Tubes is the modified high carbon version of Stainless Steel 321 a general purpose austenitic SS that is strengthened against carbide precipitation. Stainless Steel 321 Seamless Pipes are used in various applications owing to their enhanced creep resistance and superior toughness at temperatures above 537 degrees C. Our SS 321H Seamless Tubes are known for their features like durability, seamless finishing, easy machinability, ready weldability by most standard methods, and dimensional precision and highly demanded across India. SS 321H Seamless Pipes are designed 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 Piston Engine Manifolds, Petrochemical Equipment, Expansion Joints, Breweries, Oil and Gas Refining, Thermal Oxidizers, and Pharmaceutical Production, etc. 321H Stainless Steel Seamless Pipes can be utilized in most diluted organic acids at medium temperatures and in pure phosphoric acid at cycrogenic temperatures and up to 10% diluted solutions at high temperatures. SS 321 Seamless Pipes are immune to 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 pipes and tubes and conduct numerous quality tests such as Hardness Testing, Chemical Analysis, Positive Material Identification Testing, and so on.
