<p>A maraging steel for use as a mould steel is disclosed. In general, the use of maraging steels in moulds is limited by the fact that the martensitic microstructure is not stable at temperatures above 480 °C. The precipitate hardening maraging type steel according to the invention contains titanium, molybdenum, cobalt, chromium and nickel and has, in addition to high strength, good ductility, small thermal expansion coefficient and good thermal conductivity, a significantly better thermal stability than other maraging steels, which makes it suitable for use as a mould material particularly in pressure casting.</p> |
