Stainless Steel 347 / 347H Pipe & Tubes

SS 347 Seamless Pips Manufacturer, SS DIN 1.4550, 1.4961 Pipes & Tubes, SS 347H Welded Tubes Exporter.

Simplex Fittings is one of India’s leading manufacturers of high quality Stainless Steel 347 /347H Pipes and Tubes as per international standard quality of raw materials which find application all over different sectors.

Stainless Steel 347 Pipes Tubes is a stabilized austenitic material, which is quite similar to Stainless Steel 304 by means of an addition of Tantalum and Columbium content in it. Well, the columbium content in SS 347 Pipes Tubes (UNS S34700) serves to form a stabilized type of stainless steel that is relatively resistant to chromium carbide precipitation. Stainless Steel 347H Pipes Tubes are suggested for the parts that are being fabricated by welding and which cannot be consequently annealed, or also for the parts which should function in service range of between 800 Deg F to 1600 Deg F. These SS 347H Pipes Tubes (UNS S34709) are being used for several applications such as in collector rings, annealing box covers, airplane exhaust stacks, jet engine components, expansion joints, flexible metal hose, bellows, tubing, fasteners, etc.
