Alloy 347 is a stabilized, austenitic, chromium steel containing columbium which allows for the elimination of carbide precipitation and consequently, intergranualr corrosion. Alloy 347 is stabilized by the additions of chromium and tantalum and offers higher creep and stress rupture properties than alloy 304 and 304L which may also be used for exposures where sensitization and intergranualr corrosion are of concern. The addition of columbium also allows Alloy 347 to have excellent corrosion resistance, even superior to that of alloy 321. 347H is the higher carbon composition form of Alloy 347 and demonstrates improved high temperature and creep properties.
347/347H stainless steel is type of common austenitic stainless steels such as 304, 316 and 321, but also contains columbium and is most widely used in high temperature applications. 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 similar to grade 321, but with slightly improved corrosion resistance in strongly oxidizing environments. Stainless steel 347 is essentially non-magnetic in the annealed condition and can only be hardened by cold working.
When we set up our stockholding division ‘Stock Services’ in 2008 we begun with the goal of becoming one of the top three distributors of stainless steel SEAMLESS fittings, buttweld pipe fittings, forged pipe fittings & pipe flanges in India. In 2010 we’ve got our own manufacturing plant in India and Ras Al Khaimah & since then we have developed our range further to include SS 347 Elbow, SS 347 Tee, SS 347 Flanges, SS 347 Reducer, SS 347 Pipe Fittings, Steel 347 Fittings. Our range of seamless pipe fittings and pipe flanges are held in dual certified grades 304/304L and 316/316L, and you can find accurate & best price here on our website.
We can now provide fittings and flanges in one package, and with our experience in distribution, can ship Stainless Steel 347 Fittings, Steel 347 Pipe Fittings, Stainless 347 Pipe Fittings all over the world on quick lead times.
Below are our available Stainless Steel 347 Pipe Fittings that will meet your project needs. We will help you put together your entire project and ship it to your closest port. We ship globally!
