Abstract: Effect of Ni content on mechanical properties of 0Cr17Ni4Cu4Nb stainless steel was studied.The results show that adding Ni element reduces the amount of delta-ferrite in the steels.The particles of the rich copper are small and densely distributed in the steel with higher Ni content,while in the lower Ni content steel the rich copper particles are relatively large and distribute sparsely.At the same aging temperature,alloys with higher Ni content have relatively high strength and low plasticity.
