Definitions
- the present invention relates to a hot-forming steel alloy with high toughness and at the same time a great hardening depth and/or improved martensitic through-hardening capability with a thermal quenching and tempering of products such as, for example, die-casting dies or extrusion dies and the like.
- a thermal quenching and tempering of a part, e.g., of hot-forming steel, to adjust a high material hardness at operating temperatures of the part up to about 550° C. and more essentially means heating the material to a temperature at which it has a cubic face-centered atomic structure or an austenitic structure, followed by a forced cooling to obtain a martensitic structure and a subsequent tempering treatment, optionally multiple times, at temperatures of generally more than about 500° C.
- the stresses in the material formed during the cooling and structural transformation are reduced at least in part, and on the other hand the material hardness is increased or a so-called secondary increase in hardness is achieved due to carbide precipitates.
- a transformation of an austenitic structure into a martensitic structure calls for a minimum cooling rate of the material, because this transformation takes place as a diffusionless flip-over process of the atomic structure due to a markedly high subcooling. Lower cooling rates lead to the formation of a bainite or pearlite structure.
- the properties of a material depend on the chemical composition thereof and on the microstructure thereof adjusted by a thermal treatment and produce therefrom a specific property profile of a part.
- the chemical composition of a material and the intensity of the cooling or the heat dissipation from the surface during the hardening of the part determine the microstructure in the region of the surface and, due to the rewarming from the interior of the part, the microstructural development depending on the distance from the part surface.
- the respective local fine structure determines the material properties of the thermally quenched and tempered material locally present.
- hot-forming materials for die cast molds and the like are subject to increasing stresses through shortened press sequence times and increased casting pressures. Furthermore, complex geometries of the mold cavities are provided to an increasing extent, so that much higher total stresses of the material are present overall. These total stresses can cause tool failure due to stress cracks, fire cracks, coarse fracture, corrosion and erosion, so that materials with a high hardness and strength as well as high toughness and ductility at the same time are required. However, these required properties depend on the chemical composition of the alloy and the tempered properties of the same resulting therefrom.
- Material no. 1.2343 is used for “highly stressed tools, dies and presses.”
- the above materials have a high hardening depth and a deep-reaching tempering quality to required hardness values between 50 and 55 HRC.
- their toughness properties are low, which can be a disadvantage for the wearing qualities of die casting molds.
- the present invention provides a hot-forming steel alloy.
- the alloy comprises the following elements in % by weight, based on the total weight of the alloy:
- Carbon (C) from about 0.35 to about 0.42
- Silicon (Si) from about 0.15 to about 0.29
- Manganese (Mn) from about 0.40 to about 0.70
- Molybdenum (Mo) from about 1.50 to about 1.95

- Chromium (Cr) from about 4.80 to about 5.20
- Molybdenum (Mo) from about 1.55 to about 1.90
- V Vanadium (V) from about 0.45 to about 0.70
- Nitrogen (N) from about 0.012 to about 0.015.
- the alloy may comprise, in % by weight:
- Carbon (C) from about 0.37 to about 0.40
- Silicon (Si) from about 0.18 to about 0.25
- Manganese (Mn) from about 0.50 to about 0.58
- Chromium (Cr) from about 4.90 to about 5.10

- V Vanadium (V) from about 0.52 to about 0.60
- Nitrogen (N) from about 0.012 to about 0.015.
- the present invention also provides a part which comprises the alloy of the present invention as set forth above (including the various aspects thereof).
- the part may, for example, be a die-casting die or an extruder, or a part of a die-casting die or an extruder.
- FIG. 1 is a graph showing impact strength values of tested materials after a thermal quenching and tempering as a function of the cooling parameters in the hardening treatment.
- the present invention provides a hot-working steel alloy which comprises the alloying elements in the following concentrations in % by weight, based on the total weight of the alloy:
- the elements overall in particular the elements silicon, molybdenum, vanadium and nitrogen, are coordinated with one another in terms of transformation kinetics so that a desired strength and hardness with a high toughness of the material can be achieved with a thermal quenching and tempering with a reduced cooling rate during hardening.
- a further significant increase in the toughness properties of the tempered and quenched material can be achieved when the hot-working steel alloy has the following concentrations of one or all of the following impurity elements in % by weight, based on the total weight of the alloy:
- the above elements can form either precipitates or compounds which are enriched in particular at the grain boundaries and result in a leap-like reduction of the toughness properties of the material once a concentration limit is reached or they cause grain boundary coatings, which likewise have an unfavorable effect.
- the hot-forming steel alloy may contain one or more of the alloying elements in the following concentrations in % by weight, based on the total weight of the alloy:
- this alloy according to the invention which makes particular demands on a smelting technology, it is possible to achieve high toughness values of the material even with low cooling rates in the thermal quenching and tempering process with high material hardnesses.
- the test results are illustrated in FIG. 1 .
- Cooling parameter [ ⁇ ] corresponds to the time [in sec.] for a cooling from 800° C. to 500° C. divided by 100.
- the materials no. 1.2343 with standard-conforming Si contents and no. 1.2367 have a lower toughness with a quenched and tempered hardness of 44 HRC, but have a remarkable through-hardening capability, which is documented by only slightly reduced toughness values as a function of the cooling parameter.
- a test alloy W 350 according to the invention shows slightly lower toughness values at room temperature in the state quenched and tempered to 44 HRC compared to the So material no. 1.2343 (Si ⁇ 0.2% by weight), the toughness of the material remains essentially unchanged at superior high values even with reduced cooling rates or higher cooling parameters.
