Effect of elastoplastic deformation on stainless steel welding components in low-temperature aging

The simulated test for corrosion leakage which often occurs in the internal wall of single crystal growing furnace lid was carried out.Specimens undergone plastic deformation were aged at different low-temperature.Then the specimens undergone elastic deformation were conducted corrosion test.The results show that corrosion crack increase with temperature increasing.Therefore,austenitic stainless steel,undergone large elastic and plastic deformation after rolling or pressing,is inadvisable to perform low-temperature aging.
