Effect of nitrogen and chromium on the mechanical properties of austenitic steels at −196°C

Metal Science and Heat Treatment Aims and scope

Conclusion

Nitrogen lowers and chromium raises (with >3% N) the strength (σbσ0.2), ductility (δ, ψ), and fracture toughness of austenitic stainless steel of the Kh(18-24)N20 type in the aged condition. The effect of chromium on the properties is due to a change in the solubility of nitrides.
