WebIntercrystalline corrosion in chromium-nickel steels is considered from both a theoretical and practical standpoint. Laboratory tests were conducted to determine the effect on Invar alloy and 18 chromium-9 nickel alloy of boiling sulfuric acid containing copper sulfate. Specimens subjected to various heat treatment were tested. Polarization curves and passivation … WebHigh temperature microscopy during oxidation of austenitic stainless steels shows that an increased rate of oxidation is found in a narrow zone along grain boundaries where chromium carbides have been precipitated. This lends support to the chromium-depletion theory of intercrystalline corrosion of these steels. Approximate solution of the …
