Range of Stainless Steel 347

Eka Pipe Fittings is a prominent producer, distributor, and exporter of forged fittings, flanges, and buttweld pipe fittings made of stainless steel 347 (1.4550) and 347H (1.4961).

A comprehensive selection of stainless steel 347 pipe fittings, including stub ends, reducers, elbows, tees, crosses, end caps and bends, are available from Eka Pipe Fittings. The production of stainless steel 347 and 347H pipe fittings complies with ASTM A-403, ANSI B16.9 / 16.28/MSS SP-43, and ANSI B 16.25 welding bevel standards.

We are experts in the manufacture and supply of SS 347 pipe bends in both standard and non standard sizes, with bending radius of 1D to 10D or any other custom bending radius. We provide a variety of standard size and type SS 347 pipe fittings, flanges, and bends ex-stock.

Our expertise lies in producing and distributing SS 347 big diameter fabricated pipes, SS 347 reducers, SS 347 tees, and large size fabricated elbows that have undergone 100% radiography testing.

304, 316, and 321 are examples of common austenitic stainless steels; however, 347/347H stainless steel additionally contains columbium and is most often utilised in high temperature situations. Stainless steel 347 has excellent forming and welding qualities, and the addition of columbium and tantalum helps for exceptional intergranular corrosion resistance.

Grade 347 is comparable to grade 321, but with somewhat improved corrosion resistance in extremely oxidizing conditions. Only cold working can harden stainless steel 347, which is virtually non-magnetic when it is annealed.

In addition to our current production range of SS 316 buttweld fittings and SS 316 flanges, Eka Pipe Fittings also stocks and distributes a full variety of SS 316 | 316L pipes. 316/316L stainless steel pipes can be machined or built to match your specific piping needs, in addition to being supplied in length sizes that can be cut to fit.

Key Properties of Stainless Steel 347 Pipe Fittings, SS 347 Flanges

  • Stainless steel 347H offers high temperature creep properties
  • Improved intergranular corrosion resistance
  • Superior general corrosion resistance over Type 321
  • Superior high temperature properties than 304 or 304L
