Abstract:The crevice corrosion resistance of Inconel alloy 625 has been investigated as a function of its niobium content. A technique used primarily for mathematical modelling of crevice corrosion in chloride media has been used to compare the probable resistances to this type of corrosion. It has been shown that the level of niobium can be reduced from that in the commercially available alloy – thereby offering a more cost effective alternative – while maintaining favourable crevice corrosion resistance and mechanical properties. In addition, it was found that a solution annealing treatment of the alloy variations produced further beneficial properties in the alloy.
