Conclusions 1. A reduction of the grain size of cast parts of steel 15Kh1M1F from 40 to 15 μ increases the probability of obtaining high ductility at room temperature and higher values of the long-term ductility at 565°C. 2. The long-term strength is hardly affected by grain refining within these limits, and depends mainly on the ratio of the structural components. 3. To ensure maximum values of the long-term ductility of cast parts of boilers and turbines it is necessary to study the factors controlling the optimal grain size.
