718 Nickel Ogee Washers Specification
- ASME SB637
- ASTM B637
Inconel 718 Washers, as a base element, contain chromium and molybdenum with new aluminium, titanium and cobalt, which provide high strength without strengthening heat treatment. This Washer is designed to resist severely corrosive environments, pitting, crevice corrosion, pollution-control equipment, and nuclear reactors. Also, theASTM B637 UNS N07718 Plain Washer offer an excellent balance of corrosion resistance, temperature stability, toughness and strength. This material is primarily useful in chemical processing, aerospace, marine, electronic and oil and gas. The key features of the Inconel Alloy 718 Washers are long service life, dimensionally accurate, and optimum operation.
