Abstract

Certain additions to low alloy steels promote caustic stress-corrosion cracking (SCC) at relatively oxidizing potentials. Of these, the two most important are Mo and P, the latter being effective at very low concentrations when segregated to the grain boundaries. Using alloys based on Fe-3Ni, the effects of Mo additions up to 5. 2% have been compared with that of P. SCC velocities were compared with the results of potential pulsing experiments. An amorphous Fe-10P alloy was used to simulate the electrochemistry of the enriched grain boundaries in the Fe-Ni-P alloy. Both Mo and P enhance the growth kinetics of a ferric oxide film at the crack tip.
