摘要：The chromium-based alloy is used for making a chill mold for high temperatures, i.e. up to 1550 DEG C, melts. The alloy contains 15 to 35 percent cobalt and/or iron, 0 to 0.2 percent nitrogen, stochiometric quantities relative to the nitrogen of a nitride-former selected from titanium, hafnium and zirconium, and the remainder chromium up to 64 percent. The alloy has good heat conductivity, a small heat-expansion coefficient, good resistance to corrosion and a sufficient heat resistance.
