For the manufacture of advanced fuel systems such as the Common Rail system with more complex geometries and large cross-sections operating at pressures above 200 MPa, it is currently becoming somewhat difficult to guarantee high reliability of parts made of steel ShKh15. This is due to the fact that the operating modes of Common Rail type fuel systems at an operating pressure of 200 MPa are already approaching the maximum strength values of steel ShKh15. At the same time, to ensure the necessary strength properties and reliability of parts made of ShKh15 steel, rather complex, lengthy heat treatment operations are required, such as cold treatment, cryogenic treatment, multiple tempering, etc. Based on this, the replacement of ShKh15 steel with ShKh15SG steel may make it possible to avoid the use of additional heat treatment operations in the technological cycle of manufacturing fuel equipment parts, and therefore reduce the production time of parts and reduce their manufacturing cost. Based on the results of a comparison of the constructed diagrams of the isothermal decomposition of supercooled austenite, it is shown that, presumably, for ShKh15SG steel, the optimal austenitization temperature, according to the results of computer modeling of heat treatment conditions, may be temperatures of 840-880 °C, which naturally slightly exceeds the austenitization temperatures for ShKh15 steel (820-860 °C), but this will not significantly increase the cost of heat treatment. At these temperatures, a significant proportion of carbides will dissolve, and on the other hand, there should be no significant growth of the austenitic grain.
