We produce SUPERDUPLEX ASTM A182 F55, UNS 32760, EN 1.4501 screws, studbolts and nuts realised in double-phase stainless steel Cr-Ni-Mo-N pitting resistant and stressed corrosion resistant.

ASTM A182 F55 is an austenitic and ferritic structural stainless steel with a good mechanical and corrosion resistance. It is suitable to be used in case of parts, valves and pumps under pressure and subject to corrosion and in case of centrifugal pumps under heavy corrosive conditions. It is the best material among the types austenitic Cr-Ni even in presence of chlorides and moreover when further to corrosive conditions we also have mechanical stress. The corrosion resistance of ASTM A182 F55 gets the maximum result at soluble status and we recommend not to use it at temperatures higher than 300°C.

ASTM A182 F55 can be welded by using common means and can gets soluble after the welding operation.
