Modern steels for pressure die-casting molds

1. The service life of pressure die-casting molds can be improved substantially by using corrosion resistant steels in place of the heat resistant die steels used at the present time. 2. The heat resistance of corrosion resistant steels can be improved by alloying with molybdenum and tungsten. 3. Steels 18Kh12VMBFR, 2Kh9V6, and 4Kh4MVFS are the most suitable for pressure die-casting molds used for copper alloys, and steels 2Kh9V6 and 2Kh10MFN and die steel 4Kh5MFS for aluminum alloys.
