Abstract

PURPOSE: To accurately detect the sensitivity of austenitic nickel alloy to intergranular corrosion and stress corrosion cracking in a short time, by determining the relationship between the degree of sensitization of the alloy and its magnetic permeability.
CONSTITUTION: The correlation between the change in the sensitivity of the austenitic nickel alloy to intergranular corrosion and stress corrosion cracking and that in its magnetic permeability is previously determined. The magnetic permeability is measured to detect said sensitivity. The austenitic nickel alloy contains 25% or more of nickel and 10% or more of chromium.
