This paper presents a method for the low cycle fatigue life expectation assessment with safety confidence of steam turbine components. The method is based on theories of probability and statistics. considering the low cycle fatigue life of steam turbine components to be a random variables : depending on concrete conditions. The low cycle fatigue life distribution parameters of the materials are estimated by statistical methods and low cycle fatigue test data. Low cycle fatigue life expectation with safety confidence of steam turbine components is calculated by applying the reliability theory. For low cycle fatigue life of steam turbine components with normal or a logarithmic normal distribution. a calculation method of the life expectation with safety confidence is given together with a practical example.
