Abstract

In order to clarify the SCC initiation and propagation path of L-grade stainless steel, directionally solidification material was prepared and SCC test has been carried out. Creviced bent beam (CBB) test was performed in the high temperature water. Crack initiated in the cold worked surface, which was made for accelerating the crack initiation in L-grade stainless steel, and propagated along the austenite (γ) / ferrite (δ) boundary. The γ/δ boundary had a large misorientation compared with the γ/γ boundary. It was thought that there was a close relationship between a crack path and misorientation of the neighboring crystals. After the simulated welding heat treatment (700°C/10hr), the σ phase was created in the part of σ phase, and it was considered that this phenomenon may affect the SCC susceptibility.
