Description

  

   <Desc/Clms Page number 1> 
 



  Bei hohen Temperaturen hohe Festigkeit aufweisende Stahllegierungen. 



   Die Erfindung betrifft Stahllegierungen, die bei hohen Temperaturen hohe Festigkeit aufweisen und zu diesem Zwecke erfindungsgemäss neben einem bis   1%   betragenden Kohlenstoffgehalt 8-18% Chrom, 2-12% Mangan und 3-12% Wolfram enthalten. 



   Als ganz besonders warmest haben sich Stahllegierungen erwiesen, die bis   0'5%   Kohlenstoff,   12--14%   Chrom, etwa 5% Mangan und etwa 5% Wolfram mit den sonst üblichen geringen Beimengungen von Silizium, Schwefel und Phosphor enthalten. 



   Die Art der Wärmebehandlung ist ohne wesentlichen Einfluss auf die Warmfestigkeit der Legierungen. Von bereits bekannten Stahllegierungen, die bei hohen Temperaturen hohe Festigkeit aufweisen, unterscheiden sich die vorliegenden dadurch, dass sie nickelfrei sind und Silizium nur als Verunreinigung enthalten. 



   PATENT-ANSPRÜCHE :
1. Bei hohen Temperaturen hohe Festigkeit aufweisende Stahllegierungen, dadurch gekennzeichnet, dass sie neben einem bis zu   1%   betragenden Kohlenstoffgehalt 8-18% Chrom,   2-12%   Mangan und 3-12% Wolfram enthalten.

  Steel alloys with high strength at high temperatures.



   The invention relates to steel alloys which have high strength at high temperatures and for this purpose according to the invention contain 8-18% chromium, 2-12% manganese and 3-12% tungsten in addition to a carbon content of up to 1%.



   Steel alloys that contain up to 0'5% carbon, 12--14% chromium, about 5% manganese and about 5% tungsten with the otherwise customary small admixtures of silicon, sulfur and phosphorus have proven to be particularly warm.



   The type of heat treatment has no significant influence on the high temperature strength of the alloys. From already known steel alloys, which have high strength at high temperatures, these differ in that they are nickel-free and only contain silicon as an impurity.



   PATENT CLAIMS:
1. Steel alloys exhibiting high strength at high temperatures, characterized in that, in addition to a carbon content of up to 1%, they contain 8-18% chromium, 2-12% manganese and 3-12% tungsten.
