|Higher content of Ni and Mo alloys, pearlite, bainite and martensite matrix with excellent performance. It has the higher conductivity of thermal and high tensile strength. A dense net primary cementite with high wear-resistance is produced through changing the heat treatment technology and the composition of the structure with bainite, martensite and acicular nodular.|
