Abstract (en)
[origin: US4382828A] White, chromium cast iron having shock and impact resistance which comprise iron together with: -Carbon: 2.2 to 3.6% by weight -Chromium: 12.0 to 30.0% by weight -Molybdenum: 0.0 to 3.0% by weight -Nickel: 0.0 to 3.0% by weight -Manganese: 0.0 to 2.0% by weight -Copper: 0.0 to 3.0% by weight -Vanadium: 0.0 to 1.5% by weight - are disclosed. The casting are produced by casting the molten alloy in a metallic permanent mold, removing the solidified casting from the mold at a temperature above the Ac3 temperature and cooling the casting sufficiently quickly to prevent the formation of pearlite as well as secondary carbide precipitation.

Es wird ein Verfahren zur Herstellung von vorwiegend austenitischem weissen Chromgusseisen mit 2,2 - 3,6 % C, 12 -30%Cr, 0-3%Mo und 0-3 % Ni, 0-2 % Mn, 0-3 % Cu sowie 0 - 1,5% V für prall- und schlagbeanspruchte Gusstükke zum Geissen in metallischen Dauerformen angegeben, wobei oberhalb der Ac3 Temeratur ausgepackt und genügend schnell abgekühlt wird, um die Perlitbildung sowie eine Sekundärkarbidausscheidung zu verhindern.
