Cast steel castings resistant to high-temperature corrosion

High-temperature corrosion in carburizing atmosphere leads to deterioration of strength properties of castings made from creep-resting cast steel and there by they become less resistant to thermal shocks and less creep-resistant. In this paper the methods of protection of castings made from Ni-Cr cast steel against carburizing atmosphere are presented. The obtained results are the authors efforts put into the improvement of service life of castings working as constructional elements in carburizing furnaces. [...]
