摘要：

The effect of up to 0.5 mass% C on a steel with 18 to 19 mass% Cr and Mn each and about 0.6 mass% N was investigated by tensile tests, notch impact tests and corrosion tests. The experimental results show that the solution anneal temperature and the sensitisation to intercrystalline corrosion depend on the carbon content which raise the strength and cold work hardening. Up to 1 mass% C+N the ductile to brittle transition temperature remains at about -90 degrees C. Corrosion in diluted aqueous solutions of H(2)SO(4), HCl and NaCl is described.
