Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Super Duplex S32750 Hydraulic Fittings, which is a solid solution alloy that can be hardened by the process of cold working. The proportions of copper and nickel used to make Super Duplex S32750 Hydraulic Fittings are the same as that found in the nickel ore found in Ontario mines. These Super Duplex S32760 Hydraulic Fitting exhibits good corrosion resistance, where the machinability is difficult as it work – hardens during machining. The conventional machining techniques used on iron alloys may be used for Super Duplex S32750 Hydraulic Type Fitting.
Welding methods including gas – arc welding, metal – arc welding, gas – metal – arc welding and submerged – arc welding are recommended on these Super Duplex S32760 Hydraulic Type Fittings. Hot working on Super Duplex S32750 Forged Hydraulic Fittings needs to be done by choosing proper temperatures.
Typical temperatures of these Super Duplex S32760 Forged Hydraulic Fitting have hot working between the ranges of 648 Degree C – 1176 Degree C (1200 Degree F – 2150 Degree F). Super Duplex Steel S32750 Hydraulic Forged Fittings (about 67 % Ni – 23 % Cu) is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. These Super Duplex Steel S32760 Hydraulic Forged Fittings is a solid solution alloy that can only be hardened by cold working.
