Duplex ASTM A182 F51 SCREWS, NUTS, STUD BOLTS |
|
We produce ASTM A182 F51 DUPLEX, UNS 31803 EN 1.4462 screws studbolts and nuts stainless steel Cr-Ni-Mo-N double-phase pitting and stressed corrosion resistant.
ASTM A182 F51 DUPLEX, UNS 31803 EN 1.4462 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 austenitic Cr-Ni types even in presence of chlorides and moreover, when further to corrosive conditions we also have a mechanical stress. The corrosion resistance of ASTM A182 F51 DUPLEX, UNS 31803 EN 1.4462 gets the maximum result at soluble status and we recommend not to use it at temperatures higher than 300°C.
ASTM A182 F51 DUPLEX, UNS 31803 EN 1.4462 can be welded by using common means and must be soluble after the welding operation.
