Their superiority in resisting pitting and stress corrosion cracking is especially evident in environments containing the chloride ion. This performance is obtained by using a high level of chromium, nickel, molybdenum, and nitrogen alloying for corrosion resistance, and by High- Performance Stainless Steels Nickel Institute

Many of these alloying elements can be combined with nickel in single phase solid solutions over a broad composition range to provide alloys with useful corrosion3. Chemical resistance of a material does not necessarily indicate the suitability of a fitting in a given application due to variables such as improper clamp and coupling application, special hose construction, gasket material, etc. 4.

Corrosive Environments
Within the realm of corrosion-resistant nickel- and cobalt-based alloys, the nickel-copper alloys are the most commonly utilized for industrial applications involving hot, pure, aqueous solutions of hydrofluoric acid. The results were used to create simplified corrosion rate charts, with indicators (black crosses) as to the temperatures andElectroless nickel does not have the high temperature properties of pure nickel, e.g. high temperature oxidation resistance. Pure nickel has a melting point of 1455°C but the phosphorus content of electroless nickel has a very sig-nificant effect on its melting point, as shown in Figure 2.

Comparative Analysis of Corrosion-Resistant Alloys Inconel
Comparative studies of precipitation-hardening corrosion-resistant nickel-base alloys used in the oil and gas industry are conducted. Corrosion-electrochemical properties of ÉP718 and Inconel 718 alloys are studied, and composition and microstructure are analyzed. It is observed that the passivity of these alloys may be affected significantly metal with good corrosion resistance. The film is highly insulating. The corrosion that eventually results may be manifested either uniformly or as pitting, but nickel is generally quite corrosion resistant in mild environments.
