Hastelloy flanges are made from nickel based alloys. These flanges have high-temperature strength and excellent corrosion resistance. These Hastelloy pipe flange are designed to provide leak free connection between pipe and fittings in corrosive environments. The high content of chromium is providing excellent resistance ability to oxidizing media. Hastelloy forged flange have strong resistance against various aggressive corrosions which includes crevice corrosion, stress corrosion cracking and pitting.

European Origin Hastelloy Slip On Flange Supplier in Class 150 To 2500

The Hastelloy weld flanges also show good strength at high temperatures. The most generally used welding method which is used to attach a Hastelloy slip on flange to a pipe TIG (tungsten inert gas) welding process. Hastelloy alloy hot forged flange have strong mechanical properties. These flanges are known for withstanding stress corrosion and that is why the material is used in various petrochemical applications. Rishabh Steel Industries is one of the leading Hastelloy flanges manufacturer in India. We are an ISO 9001:2008 certified company with an existence in the metal market since 1997.
