PITTING STABILITY OF AISI 321 IN CHLORIDE CONTAINING MEDIA
Abstract
The influence of ?-ferrite amount ferrite in AISI 321 steel on its general corrosion, critical pitting temperature and potential in simulated circulating waters. The samples were made in the form of rectangular 3x3x1 mm parallelepipeds by cold mechanical method. Surface of the samples was subjected to electro-polishing. The amount of ferrite phase was determined by empirical formula. It was established, that after electromagnetic saturation of the samples, ?-ferrite content in five heats of AISI 321 steel was calculated. Research has shown, that ?-ferrite content varied from 0.099 smelting 4 to 0.36% by melting 2 and 3. It is established that the content of ?-ferrite in AISI 321 steel affects its pitting resistance in low-mineralized chloride-containing media. It is shown that in a chloride-containing solution with a pH of 4 and a chloride concentration of 600 mg / l, a parabolic dependence takes place between the ATP steel of AISI 321 steel and its ?-ferrite content. With an increase in the ?-ferrite content from 0.099 to 0.24% by volume, the critical pitting temperature of steel increases to 50.5 ??, and with a subsequent increase in the volume of ?-ferrite to 0.36% by volume, the critical pitting temperature of steel decreases to 44 ??.
