Stainless Steel 304 / 304L Flanges

National India. Co (India) is Most Widely Used Austenitic Stainless Steel 304 Flanges, DIN 1.4301 SS Plate Flanges, ASTM A182 SS 304 Long Weld Neck Flanges, SS 304L Spactical Blind Flanges , SS 304L Pipe Flanges, Stainless Steel DIN 1.4306 Loose Flanges, SS 304 Industrial Flanges, 304L SS Socket Weld, 304 SS Orifice Flanges Supplies in India.

We provide an extensive collection of SS 304 / 304L Flanges, which are carefully inspected by the gathering of experts in order to ensure that these products, are secured to perform and utilize deprived of any deficiencies. SS 304L Flanges (UNS S30403) is a variation of SS 304 and has a low content of carbon that recovers weldability and drops the hazard of condensed resistance to corrosion around the weld. Stainless Steel 304L Flanges is the ordinary “18/8 alloy” that is typical found in cooking and pans tools.

Also referred as UNS S30400, these Stainless Steel 304 Flanges is a ring of steel (cut from plate, rolled or forged) which is being intended to join parts of pipe, or to interface pipe to a valve, pump, pressure vessel or other fundamental flanged assembly. Otherwise called as UNS S30403, these Stainless Steel 304L Flanges are connected to each other by bolting, and are also connected to the piping system by threading or welding (or loose when stub ends are being used).

Post-weld strengthening is not vital in SS 304 Flanges when welding thin parts. Stainless Steel 304 Flanges (UNS S30400) has incredible oxidation / corrosion resistance acknowledgments to the content of chromium. We also offer these Flanges in altered form with respect to its sizes and shapes.

You can get the exact material according to your requirement at the least possible price. We also provide Reworks, FOB, CFR, CIF, and door to door delivery prices. The materials we offer are completely verifiable, right from raw material test certificate to the final dimensional statement. E-guarantee to give a response within 24hours working hours (usually in the same hour).You can also get stock alternatives, mill deliveries with minimizing manufacturing time. We are completely dedicated to our customers.
