Stainless Steel 304 / 304L / 304H Pipes & Tubes
Stainless Steel DIN 1.4301/ 1.4306/1.4307 Pipes & Tubes, AISI 304L ERW Tubes Manufacturer & Exporter
Citizen Metals is a leading manufacturer and exporter of Stainless Steel 304, 304L, 304H 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 304 Pipes and Tubes (WNR 1.4301) is the most extensively used stainless steel with the finest all round performance. These SS 304L Pipes and Tubes (WNR 1.4307) are less vulnerable to intergranular corrosion after welding. SS 304H Pipes and Tubes (WNR 1.4948) is although non-magnetic but somewhat magnetic when cold worked. The carbon content of SS 304 Seamless Pipes and SS 304L Welded Tubes is inferior and its corrosion resistance after welding is superior to SS 302 Pipes and Tubes.
