CHROM-ALUMINIUM-STAEHLE FUER DEN DAUEREINSATZ BEI HOHEN TEMPERATUREN

摘要

Paper presents the results of substantial investigations of heatproof chrome-aluminium steels. Chemical compositions of steels have been optimised in dependence of exploited conditions and of peculiarities of casting's design. The working term of castings, made from these steels, at temperatures up to 1350°C increased twofold to threefold comparatively with chrome-nickel steels.
