Abstract In this paper the effect of different quenching and tempering temperature on microstructure and hardness of a new type aging hardening plastic die steel 1Cr4Ni3CuAlSi is studied.The experimental results show that it is reasonable that the steel were quenched at 850��-890��.The hardness of the steel can be improved remarkly when tempering at 510��-550�� because NiAl phase can be precipitated after tempering aging tereatment.
