Stainless Steel 347 / 347H Pipes & Tubes

Stainless Steel DIN 1.4550 / 1.4961 Pipes & Tubes, AISI 347 ERW Tubes Manufacturer & Exporter in India.

 

Citizen Metals is a leading manufacturer and exporter of Stainless Steel 347 and Stainless Steel 347H Pipes and Tubes that are being designed as per the national and international standard quality of raw materials and thus making sure of their durability and high quality. SS 347 Pipes and Tubes (WNR 1.4550) are austenitic chromium steel that contains columbium. The adding up of columbium in SS 347H Pipes and Tubes (WNR 1.4961) creates a stabilized type of stainless that eradicates carbide precipitation, and subsequently, intergranular corrosion. SS 347 Seamless Pipes are suggested for parts fabricated by welding, that cannot be consequently annealed. SS 347H Welded Tubes are also used for parts that can be sporadically heated and cooled to temperatures between 800° and 1600° F.
