Ninthore Overseas is one of the Leading Manufacturer And Exporter of Inconel 718 Washers, which can be readily machined in either the annealed or the age – hardened condition. Inconel 718 Flat Washers is hardened by the precipitation of secondary phases (e.g. gamma prime and gamma double – prime) into the metal matrix. Inconel 718 Lock Washers maintains good corrosion resistance and oxidation resistance and is used for parts requiring high resistance to creep and stress rupture up to 1300 Degree F (704 Degree C). Inconel 718 Sealing Washers is used in a variety of industries such as aerospace, marine engineering, chemical processing, pollution – control equipment, and nuclear reactors. 

Inconel 718 Split Washers is also used in Gas Turbines, Space Craft, Rocket Motors, Pumps and so on. In both as – built and age – hardened states, the parts of these Inconel 718 Slot Washers can be machined, spark – eroded, welded, micro shot – peened, coated and polished if required. The excellent strength and corrosion resistance of Inconel 718 Machine Washers have been recognized by the oil industry and it is now widely used in this field.
