AISI 304 stainless steel and AISI 4135 carbon steel specimens were exposed to five wt.% (70 F) and thirteen wt.% (140 F) boric acid solutions. These are essentially saturation concentrations. After four weeks exposure it was found that the AISI 304 stainless steel was not attacked under these conditions but that the carbon steel had developed considerable corrosion products in the form of scale. It was found that the attack on carbon steel at 70 F in a five wt.% boric acid solution was greatly reduced by the addition of sufficient base to neutralize the solution. A thirteen wt.% boric acid solution badly attacked the carbon steel at 140 F even when adjusted to neutral pH conditions. (auth)
