Abstract
The present experiment was carried out for finding the change of solubility of iron and steel in acid, caused by cold-working. The specimens to be tested were previously strained by means of tensile, torsional, impact and compression tests and then they were subjected to the action of one percent sulphuric acid and the loss in weight determined after 72 hours. All the results dealt with in the present experiment led to the conclusion that specimens deformed by stress beyond the elastic limit showed a measurable difference of solubility and the greater the strain, the greater was the corrodibility.
