INDIAN Super Duplex ASTM A182 F55 Fasteners

Swagat Steel And Alloys is the leading supplier , stockist , manufacturer and exporter of Super Duplex ASTM A182 F55 Fasteners . We provide Super Duplex ASTM A182 F55 Fasteners that are made of double phase stainless steel. It is corrosion resistant and Cr-Ni-Mo-N pitting resistant. Our range of product is an austenitic and ferritic structural stainless steel and has a good mechanical and corrosion resistance. It is extensively used in case of parts, valves and pumps under pressure. It is also subject to corrosion and in case of centrifugal pumps. When Super Duplex ASTM A182 F55 Fasteners are at soluble states; their corrosion result gets the maximum result. Features 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 Super Duplex ASTM A182 F55 can be welded using common means and can get soluble after the welding operation Recommended not to be used at temperatures higher than 300oC Comparable Specifications EN 10088/3 X2 Cr Ni Mo Cu W N 15-7-4 W. 1.45 JIS - AISI F55 Nominal Chemical Composition C 0.02 S < 0.005 P 0.03 Si 0.5 Mn 0.6 Cr 25 Ni 7 Mo 3.6 Cu 0.6 W 0.60 N 0.25 Physical Properties Density g/cm3 20oC 7.75 Modulus of Elasticity N/mm2 20oC 206.000 Thermal Conductivity W/m.K.
