    Abstract:

    Through the study on the effect of carbides on properties of hot work die steels by the Thermo-Calc
    software, the compositions of a new type heat strength and corrosion resistance steel were designed preliminary. Microstructures
    and properties were characterized. The matrix structure of this steel was martensite, in which carbides
    dispersed. The tensile strength of this steel was as high as 2 067 MPa at room temperature. The hardness was about
    50HRC, when tempered at 620℃ for 2 hours,corrosion resistance of the steel was good in NaCl.
