摘要：

Results of determination of short-time properties, of limiting stress tests at 565 degree C of the metal of commercial production castings of 15Cr1Mo1V cast steel and of two melts with a reduced content of molybdenum are presented. It is shown that it is possible to correct the chemical composition of cast steel 15Cr1Mo1V for steam turbine frames and fittings if the content of the alloying element, molybdenum, which is in short supply, is reduced. Practical recommendations are given as a basis of unification of heat-resisting steel Cr-Mo-V.
