Abstract

Fatigue crack growth properties for SUS 316 stainless steels containing nitrogen in the mass, percent from 0.001 to 0.66 were investigated in air at room temperature. The near-threshold fatigue crack growth properties for SUS 316 steel containing 0.001, 0.02 and 0.07 mass. % N were coincident each other. On the other hand, SUS 316 steels containing 0.24, 0.25, 0.40 and 0.66 mass. % N showed the remarkable decrease in fatigue crack growth rate and 50% increase in fatigue threshold. This behavior was related to the slip deformation at the fatigue crack tip. The slip deformation was localized for low nitrogen steels, while it was uniformed for high nitrogen steels.
