Abstract
The failure of stainless steel condenser tubes in a heat exchanger was analysed using optical and scanning electron microscopic techniques including EDAX. The presence of tensile stresses and of chloride ions in the cooling water and the corrosion deposits as well as the transgranular morphology of the cracks lead to the conclusion, that the failure of the tubes was caused by stress corrosion cracking. The author would like to thank the Indo-Gulf Fertilizers and Chemicals Corporation, Jagdishpur, Uttar Pradesh, India for financial support
