The authors study how cadmium ions influence the plasticity of steel during pickling. The specimens were rods 0.8 mm diameter, 120 mm long, of steel KT-2, and were pickled for 30 min at 25 c in solutions of sulfuric acid and ferric sulfate, then washed with water and subjected to twisting. It is shown that when the sulfuric acid concentration is altered from 60 to 180 g/liter the fall in plasticity changes from 12.6 to 23.0%. In the presence of at least 10 g/liter of cadmium sulfate in the same solutions the fall in plasticity decreases to 4.6-8%. Thus, cadmium ions have a marked influence on the plasticity of steel in pickling in sulfuric acid solutions at low temperatures.
