| Abstract: | Pitting corrosion found on the fire tube surface of boiler is the reason for producing the residual stress and structure defect when the fire rubes were formed by cold roiling,and this will result the stress corrosion under the corrosive medium action. Based on test - researching and analyzing, it is shown that the stress corrosion of boiler fire-tubes car. be prevented by full annealing. |
