摘要：

The influence of nitrogen on austenite grain growth, chromium content in carbides and corrosion resistance have been studied in chromium steels and alloys containing of about 13% Cr. The results shows that the inhibiting effect of nitrogen on austenite grain growth is observed in steels and alloys saturated in nitrogen by several methods. Vacuum treated steels with very low nitrogen content tend to have large grains in austenitization treatments. Carbon and nitrogen disolved in austenite reduces the chromium content in carbides being in equilibrium with austenite. The influence of carbon is more pronounced. Nitrogen containing steels are more resistant to pitting corrosion as steels with carbon.
