Siddhagiri Metals and Tubes is the Manufacturer, Exporter, and Supplier of 254 SMO. Siddhagiri Metals and Tubes has 25 years of Experience in Manufacturing of SMO 254 in India.We have been exporting this alloy all over the world. We supply SMO 254 Pipe, Tube, Wire, Flanges, Fittings, Forged Fitting, Filler Wire, Tube Fitting, Outlets, Elbow, Tee, Round Bar, Plate, Sheet, Coil etc. Stainless Steel Grade SMO 254 is very high end austenitic stainless steel developed for use in seawater and other aggressive chloride bearing media. It is designed with a combination of impact toughness resistance to chloride stress corrosion cracking, pitting and crevice corrosion with a strength that is twice of stainless steel 300 series. For certain applications, SMO 254 has been reported to be a cost effective substitute for high Nickel and Titanium alloys.

254 SMO alloy also known as UNS S31254,  possess excellent workability as well.It offers high yield strength, Owing to its excellent corrosion resistance, ducting and welding properties, the offered Austenitic Stainless Steel is widely used in chemical industry & food processing equipment and truck & trailer body manufacturing purpose. Excellent resistance to pitting and crevice corrosion High resistance to general corrosion High resistance to stress corrosion cracking Higher strength than conventional austenitic stainless steels Good weldability. 254 SMO Seamless PIPES AND TUBES are supplied in dimensions up to 230 outside diameter. The delivery condition is either solution annealed and white pickled, or solution annealed in a bright annealing process.
