Conclusions 1. In terms of the interaction with liquid alloys, all steels can be divided into three types: high stability in liquid alloys (corrosion-resistant steels 2Kh9V6, 35Kh10AVMNFS, 2Kh10VMNF), moderate stability (4Kh5MFS, 4Kh5V2FS, 4Kh4VMFS), and low stability (3Kh2V8F, 3Kh3M3F). 2. The higher the casting temperature, the greater the interaction of the steels with the liquid alloys. Steels with the same heat resistance react differently with the alloys—the higher the chromium content of the steel, the smaller the interaction. 3. The white layer on the steel mold used for casting copper alloys consists of a solid solution of copper in iron; on molds used in casting aluminum and zinc alloys it consists of intermetallic compounds. 4. Molds used in casting copper and aluminum alloys are subject to considerable thermal erosion and build-up, while molds used in casting zinc alloys are subject to build-up and wear. 5. For molds used in casting aluminum alloys, we recommend standard steel 4Kh5MFS and corrosion-resistant steel 2Kh9V6, steel 2Kh10MNF for copper alloys, and steel 35Kh10AVMNFS for zinc alloys.
