Being a martensitic stainless steel with high strength, excellent workability and good damping capacity, 12% Cr steel is widely used for turbine blades. In recent years, there has been an increased demand for larger blades in order to increase the efficiency. Because turbine blades require a high strength material, it has become an important issue how far the hardness threshold can be extended. Accordingly, a study of the effect of precipitates on hydrogen embrittlement was conducted using SUS

SUS1 410J1 steel used in this study did not suffer from cracking due to hydrogen embrittlement when stable M2N was precipitated. Thus, it is concluded that the cracking could be prevented when precipitates become stable.
