Definitions

  • the invention relates to a heat-resistant bearing material made of an austenitic iron matrix alloy and deals with the problem of such a bearing material for use at high temperatures functionally reliable and in particular for temperatures above 600 ° C, in particular above 850 ° C. It should This is a bearing material that has solid lubricant properties that are to be maintained at the specified high temperatures in the highest possible degree.
  • the invention is based on the general idea to provide a sulfur content in a size by which, necessary for a lubricating effect sulfides can form within the alloy.
  • Such sulphide formation Within an austenitic matrix alloy which is said to have high creep resistance and high strength at high temperatures is inherently a contradiction.
  • This contradiction arises from the fact that sulfides contained in such a material for high creep resistance and high strength as a structural disorder at high temperatures per se according to general expertise are disadvantageous and therefore to be avoided.
  • the invention therefore proposes something, which in itself with respect to the goal to obtain a high creep resistant and temperature moderately solid, even at high temperatures having solid lubricant material, the general knowledge is absolutely contrary and therefore a surprising, not by a professional represents expected result.
  • This diagram shows the coefficient of thermal expansion of alloys A and B as a function of temperature.
  • the ordinate represents the hot hardness (in HVlO) as a function of the temperature for alloys A and B.
  • the ordinate shows the hardness (in HB 2.5 / 187.5) of the alloys A and B after 2 hours aging and air cooling as a function of the temperature.
