N2 - In Taiwan, many industrial facilities are located in coastal regions. A large portion of those facilities are constructed with stainless steel. Over time, sodium chloride from seawater vapor would deposit on the surface of the facilities and the chloride ions in it can lead to corrosion and cracks, which is known as stress corrosion cracking (SCC). Theoretically, the SCC failures increase with the level of residual stress created by the welding and cold working processes. Practically, however, the SCC risk is governed by various intrinsic and extrinsic factors, which interact as a complex process. In this paper, we propose a dynamic approach for analyzing the SCC risk. Firstly, we review recent experimental work and archived investigations regarding stainless steel facilities in Taiwan. Following that, a dynamic risk approach is explained and applied to develop a research roadmap for controlling the complex SCC risk. In sum, we find that the best way to control the corrosion risk of the facilities is to remove the chlorides from the air by an ion exchange process accompanied with continuous monitoring and maintenance efforts during the facilities' operation life cycle.
