Ninthore Overseas is one of the leading manufacturer and exporter of Inconel 625 Washers, which resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion. Inconel 625 Flat Washer is often used in spray bars, turbine shroud rings, bellows and heat – exchanger tubing in environmental control systems. Inconel 625 Lock Washer is non – magnetic and immune to chloride ion stress corrosion cracking, where they form in a needle – like morphology and are incoherent with the matrix. The nickel and chromium content in Inconel 625 Sealing Washers provide resistance to oxidizing environments.

 Inconel Alloy 625 Split Washer is also used in Flue gas desulfurization scrubbers and Weld Overlay. Inconel 625 Slot Washers is as well used in is used in chemical processing, marine engineering, aerospace, pollution – control equipment, nuclear reactor applications and so on. The oxidation and scaling resistance of Alloy 625 Machine Washers is superior to a number of heat resistant austenitic stainless steels such as in Grade 304, Grade 309, Grade 310 and Grade 347 up to 1800 Degree F (982 Degree C) and under cyclic heating and cooling conditions.
