Heat treating Type 430 stainless steel above 1650 prior to cold rolling in order to produce a lower roped steel results in sensitization of the steel on fast cooling. This sensitization causes rapid intergranular corrosion in hot nitric-hydrofluoric acid solutions unless the steel is desensitized prior to immersion. The time-temperature relationship for desensitization is given. In addition, a possible mechanism for sensitization-desensitization in ferritic stainless steels is presented.
