SMO 254 Pipes are a high-alloy austenitic stainless steel developed for using in seawater and other aggressive chloride-bearing media. It is especially developed for oil and gas industry, paper and pulp industry and offshore platforms. 

The high alloying elements of 254 SMO Seamless Pipe provides extraordinary good resistance to corrosion. Due to its high alloying element of chromium and molybdenum it can resists a wide range of acids

254 SMO Stainless Steel Pipe has excellent resistance to pitting and crevice corrosion, good weldability, high resistance to general corrosion & stress corrosion cracking, high strength compared to conventional stainless steel and it is determined mainly by the chromium, molybdenum, and nitrogen content. It has high amounts of these elements which is suitable for demanding environments like chlorinated sea water.

SA 312 UNS S31254 cold hardens considerably faster than conventional austenitic grades. In complicated cold forming operations, intermediate annealing of the material may sometimes be necessary, especially if the pipe is welded.

ASTM A312 UNS S31254 is well suited for welding, and the conventional methods used for welding austenitic steels can be used. However it is somewhat more sensitive to hot cracking in connection with welding, due to its stable austenitic structure and generally welding should be performed using a low heat input. 

SMO UNS S31254 Pipe is used for Components used in petroleum production, Desalination, Food processing equipment, Flue-gas cleaning, Saltwater handling, equipment for chemical industry process, bleaching equipment in pulp and paper industry
