概要
L-grade stainless steels such as 316NG, SUS316L and SUS304L are used for the BWR reactor internals and re-circulation pipes. The L-grade stainless steels are known as typical SCC resistant materials because they are hardly thermally sensitized in usual welding process due to its lower carbon contents. However SCC of the L-grade material components were recently reported. This paper summarizes the recent knowledge and reports about the SCC behavior of L-grade stainless steels and its mitigation and improvement methods in BWR primary water condition.
