Due to its nickel-chromium content, Inconel 718 nuts have excellent resistance even against chloride-ion stress corrosion cracking. Adding molybdenum to the alloy helps prevent pitting corrosion. At the same time, Inconel 718 has very high strength and good corrosion resistance. A precipitation hardening process is required to produce high tensile strengths that can exceed 200 KSI. It is highly resistant to chloride and sulfide stress corrosion cracking. Additionally, Alloy 718 is heat treated to a hardness of not more than 40HRC, the maximum allowed by NACE MR-01-75 to prevent stress corrosion cracking. The main applications in this area are gate valves, throttle stems, fasteners, tubing hangers and fire dampers.
