Description
H12MF steel die steel of cold deformation with the increased content of chrome and inclusions of molybdenum (cf. 0,5%) and vanadium (cf. 0,2%). H12MF steel possesses good heat resistance and durability, high hardness penetration, hardenability and wear resistance. Also this steel is technological, is well processed by cutting and pressure, well ground. High hardness is defined by the high-carbon content. Steel with contents From 1,25-1,45% stalyam of a ledeburite class are, i.e. contain a carbide eutectic in a cast state, have HRC 62-64 hardness after tempering. These became contain high quantity of karbidoborazuyushchy elements, the increased carbon content and chrome provides formation of the increased amount of chromium carbides (M7C3, M23C6). The total quantity of carbides makes about 20%. The basic alloying element of die steel of cold deformation is chrome (Cr). It increases the cutting properties and wear resistance, increases durability and hardness penetration of steel that is especially important for large punches and matrixes. In the presence of over 2,5% increases stability of steel against issue, especially when heating the tool to temperatures, it is above 300 °C. Together with manganese reduces a buckling when tempering. However, at staly with the content of chrome of 12% shortcomings appear. Sharply expressed carbide inhomogeneity and the increased tendency to coagulation of carbides promoting loss of strength staly when heating. Tungsten (W) is entered for increase of hardness, wear resistances and hardness penetrations became, improves cutting capacity of the tool. Vanadium (V) in shtampovy stalyakh is present at VC carbide and solid solution. Vanadium significantly reduces sensitivity shtampovy staly to an overheat, increases heat resistance of staly, improves particle distribution of an excess phase. At the content of vanadium of 0,3 - 0,5% durability and plasticity of steel will be much higher, than at high-vanadium steels. Molybdenum (Mo) is entered into high-chrome steel for increase in its viscosity and increase of hardness penetration. Also molybdenum exerts negative impact on scale resistance. Therefore the content of molybdenum in shtampovy stalyakh is limited to 1,4 - 1,8%. Manganese (Mn) is entered for increase of hardness penetration of steel. In combination with chrome molybdenum reduces a buckling when tempering, but increases tendency to an overheat. Silicon (Si) is entered to increase hardness penetration of steel, to increase firmness against issue. Thus H12MF steel with the high content of chrome belongs to semi-heatresistant stalyam. They are suitable for production of stamps, punches, rollers with a hardness of 45... 52 HRC and at an operation temperature to 700os.kupit the Forging round H12MF legko:1. You send zayavku2.
