Stainless Steel 321 Buttweld Fittings Supplier

What is SS 321 Buttweld Fittings

Universal Metal Corporation is a reputed firm that manufactures high-quality SS 321 Buttweld Fittings having considerable manufacturing experience. We offer top-class quality fittings with a wide variety of components in different types depending on form, size, length, dimensions, and other specifications. They are mostly used as bends, reducers, end caps, cross, tees, elbows, stub ends, etc. These buttweld fittings are connections between components and pipes in the piping system. Universal Metal Corporation supplies durable and strong SS 321 Buttweld Fittings of national and global quality. It is easy to choose proper specifications to fit in the application, including custom sizes. Our fittings are formed by excellent material of SS 321.

SS 321 is Nickel-Chromium austenitic steel stabilized by adding Titanium. In comparison, SS 321H is a general purpose and austenitic steel alloy that is stable besides carbide precipitation. Both are identical compositions except for advanced higher carbon in SS 321H.

 It is only hardened using a cold working technique, and in the annealed condition, it is non-magnetic. Whereas SS 321H is advanced with creep resistance and developed for higher strength at very high temperatures. Titanium suppresses chromium carbide precipitation to reduce intergranular corrosion. SS 321 is used for:

  • Strength 
  • Excellent resistance to scaling 
  • Phase stability 
  • Immune to seawater corrosion

SS 321 Buttweld Fittings are oxidation-resistant to higher temperatures with excellent creep and stress rupture qualities. These fittings maintain fine low-temperature resilience. SS 321 crosses are effectively welded with standard methods. They are immune to pitting without surface damage. These fittings are proposed in super-heater, expansion bellows, compensators, and afterburner components.

SS 321H Buttweld Fittings are improved with: 

  • Higher temperature strength
  • Enhanced weldability 
  • Strong and rigid

Crevice corrosion faced by SS 321 stub ends in humid chloride solutions is prevented in addition to stress erosion cracking. These fittings are also capable of withstanding clean water chlorides at ambient temperatures. These fittings exhibit excellent resistivity in aqueous corrosive circumstances. SS 321H Buttweld Fittings are used at high thermal levels applications such as aircraft exhaust stacks, jet engine parts, and weld equipment
