About Stainless Steel 321 Flanges

A piping system is created by connecting pipes, valves, pumps, and other machinery using stainless steel 321 flanges. Flanges are frequently soldered or bolted. Similar to grade 304, the stainless steel 321H flange is stabilised with the addition of titanium. 18% chromium and 8% nickel in SS 321 Flanges provide exceptional toughness and damage tolerance over a wide variety of media.

Properties of Stainless Steel 321 Flanges:

  • Up to 1600 ° F, SS 321 Flanges may withstand oxidation.
  • Factories created these flanges to offer a particular alloy with enhanced intergranular corrosion resistance.
  • When these Flanges are exposed to slightly corrosive situations, weld degradation is not a concern. Titanium-stabilized austenitic stainless steel with chromium and nickel provided in the annealed form; SS 321 flanges have exceptional strength and outstanding corrosion resistance.
  • These flanges are obtainable in high, minimal, and moderate grades. These flanges are solid and long-lasting.
  • These flanges are manufactured in dimensions from 1/2″ to 48″(DN10~DN5000)
  • The production techniques for such flanges are forged, heat treated and machined.
  • The 321 Flanges can withstand challenging circumstances like high temperatures and significant pressure swings.
  • A metal ring used to join valves, pipes, and other pieces of machinery to construct a pipeline is called the SS 321 Large Diameter Flange.
  • These flanges are made of alloy 321, a genuine stainless steel that has been stabilised with titanium and offers excellent resistance to corrosion damage.
  • The flange machining tools include sandblasting equipment, press equipment, bending equipment, pushing equipment, electric beveling equipment, etc.

Applications of Stainless Steel 321 Flanges:

  • These stainless steel 321 flanges are made from high-quality raw materials to ensure smooth liquid flow in various applications. Flanges made of stainless steel 321 are mainly employed to alter the path taken by liquid materials.
  • They provide reliable welding connections in fresh water and gasoline tanks and are easy to weld. These flanges are appropriate when temperature change often occurs while manufacturing is underway.
  • The 321 Grade is a common material due to its formability and weldability. These Stainless Steel 321 Flanges offer protection against various corrosive media and environmental conditions. 321 SS Flanges are widely used to connect pipes, valves, pumps, and other gear to form plumbing systems.
  • These flanges are utilised in various domestic and commercial applications, such as automotive headers, food manufacturing lines, and mechanical parts.
  • These flanges are used in a variety of industrial and residential applications, including as mechanical components, food production lines, and automobile headers.
