钢结硬质合金是介于硬质合金与工具钢之间的中间材料,适合应用在工具钢由于耐磨性不够而寿命不高,和硬质合金由于韧性不够及难加工成形而受到限制的场合。工模具用钢结合金是钢结合金的一大类,其基体所占比例为50～75％Wt,所含合金元素主要为铬和钼。这种合金材料可以用作各种模具,如冲裁模、镦模、弯曲模、挤压模、引伸模、切边模,以及耐磨零件、量具和夹具,其使用寿命一般比工具钢高几倍乃至几十倍。钢结合金工模具材料按硬质相划分,基本上为两个系列:碳化钛系和碳化钨系。我国生产
Steel cemented carbide is between the carbide and tool steel intermediate material, suitable for tool steel due to lack of wear resistance and life expectancy is not high, and due to the lack of toughness and toughness of the carbide forming is limited occasion. Tool steel alloy steel is a major category of steel, the proportion of its matrix is 50 ~ 75% Wt, containing alloying elements mainly chromium and molybdenum. This alloy material can be used as a variety of molds, such as blanking die, upsetting die, bending die, extrusion die, drawing die, trimming die, and wear parts, measuring tools and fixtures, the service life is generally higher than the tool steel Several times or even several times. Steel bonded metal mold material by hard phase, basically two series: titanium carbide and tungsten carbide. China’s production
