Corrosion of Metals by Weak Acids Under Heat Transfer Conditions^⋆ Available to Purchase

Weight-loss measurements were made on six alloys: Types 304L and 316 stainless steels, Carpenter No. 20-Cb, Hastelloy B, Inconel and Monel in solutions of 10 percent, 50 percent and concentrated acetic acid, formic acid and phosphoric acid. A special heat transfer device was used to compare corrosion rates obtained with and without heat transfer. Metal temperatures of 230 F, 257 F and 284 F were studied. Carpenter No. 20-Cb and Hastelloy B consistently showed good corrosion resistance. Of the alloys tested Monel was the most sensitive to the effects of heat throughput.
