The object of the present invention is to provide a kind of high heat resistance hot-work die steel with high thermal stability, higher hot strength, good thermal fatigue resistance.The present invention also aims to the preparation method that a kind of high heat resistance hot-work die steel is provided.
The mass percent of the chemical composition of high heat resistance hot-work die steel of the present invention is: C is 0.38% ~ 0.44%, Cr is 3.8% ~ 4.4%, Mo is 1.8% ~ 2.4%, Si is 0.2% ~ 0.6%, Mn is 0.5% ~ 0.8%, V is 0.5% ~ 0.7%, Ni is 0.8% ~ 1.2%, Cu is 0.02% ~ 0.05%, Ta be 0.08% ~ 0.12%, Nb is 0.01% ~ 0.03%, W is 0.008% ~ 0.016%, Co is that 0.008% ~ 0.016%, P and S content are all less than 0.030%, and surplus is Fe.
The preparation method of high heat resistance hot-work die steel of the present invention is:
Be C according to the mass percent of chemical composition be 0.38% ~ 0.44%, Cr is 3.8% ~ 4.4%, Mo is 1.8% ~ 2.4%, Si is 0.2% ~ 0.6%, Mn is 0.5% ~ 0.8%, V is 0.5% ~ 0.7%, Ni is 0.8% ~ 1.2%, Cu is 0.02% ~ 0.05%, Ta is 0.08% ~ 0.12%, Nb is 0.01% ~ 0.03%, W is 0.008% ~ 0.016%, Co is 0.008% ~ 0.016%, P and S content is all less than 0.030%, surplus is that Fe carries out alloying, batching, smelt, stokehold chemical composition analysis, until its chemical composition is tapped after meeting the requirements,
Carry out anneal, annealing process is: Heating temperature is 700 ~ 730 DEG C, insulation 4 ~ 6h, furnace cooling; Roughing is carried out after annealing; Carry out Quench and temper technique after roughing: quenching and preserving heat temperature is 1000 ~ 1020 DEG C, heat up with stove, soaking time 30min, oil cooling of then coming out of the stove; Tempering immediately after quenching, tempering temperature is 580 ~ 610 DEG C, and soaking time is 2h, air cooling, double tempering.
The foundation of present component design is:
Carbon: C mainly plays solution strengthening and dispersion-strengthened action in steel alloy.C is solid-solution in matrix, greatly carries heavy alloyed strong hardness; In drawing process, carbon is combined with alloying element, separates out, dispersion-strengthened matrix with carbide form.Therefore carbon is the element that heat is done die steel and must be added, and is generally medium carbon steel, in line with low-carbon and low-alloy principle, obtains good over-all properties simultaneously, controls carbon content interval 0.38% ~ 0.44%.
The effect of chromium: Cr mainly improves the hardening capacity of steel, high temperature oxidation resistance, creep resistance and high temperature corrosion resistance, simultaneously cheap because of it, thus widely uses at alloy tool steel.Cr too high levels, can cause Cr
23c
6and Cr
7c
3more, damage alloy high-temp performance.
Molybdenum: Mo is carbide, can put forward heavy alloyed thermostability, hot strength and hardening capacity simultaneously.Molybdenum content, generally more than 1.5%, just can significantly improve the high-temperature behavior of alloy, but increase with molybdenum content, promotes alloy thermal treatment decarburizing tendency, reduces the hot workability of steel.Therefore controlled 1.8% ~ 2.4%.
Silicon: Si is solid-solution in ferrite, and strengthening matrix, improves resistance to tempering and high temperature oxidation resistance, but on the other hand, reduces the plasticity and toughness of steel and increase the fragility of material.Therefore, the content general control of Si is in 0.2% ~ 0.6% scope.
Manganese: Mn is generally the effect of solution strengthening in steel, improves hardness and the intensity of matrix.Simultaneously Mn is combined into the MnS with certain plasticity with impurity S in steel, avoids the FeS of S in crystal boundary generation low melting point, eliminates the deleterious effect of S.But the too high meeting of sulphur content causes crystalline grain of steel alligatoring trend, therefore Mn content is selected to be 0.5% ~ 0.8%.
Vanadium: V Main Function is crystal grain thinning, thus the obdurability improving steel.V is carbide, the VC carbide of formation, increases steel belt roof bolt stability, thermostability and hot strength.In martensitic steel, V content reaches 0.5% just can play good age hardening effect, and too high levels can cause steel plasticity and toughness to decline, therefore control V content is between 0.4% ~ 0.6%.
Nickel: Ni is non-carbide forming element, is generally solid-solution in matrix, can improve the hardening capacity of steel, toughness and thermal conductivity.Suitable nickel controls in 0.8% ~ 1.2% scope.
Microalloy element Co, Cu, Nb, Ta and W effect in steel is different, Co improves the heat resistance of steel, and a small amount of Cu can improve intensity and the toughness of steel, and Nb, Ta are similar to element V with the effect of W, there is crystal grain thinning, improve the effect of red hardness and heat resistance.
Steel grade of the present invention mainly utilizes the alloying means of alloying elements cr, Mo, Ni and V, improve the hardening capacity of die steel, acquisition lath martensite tissue, the high-melting-point MC type carbide tiny in a large number that Mo, V, Nb, Ta and W are formed, substantially increase the red hardness of steel, heat resistance, make this steel have good hot strength, thermostability and thermal fatigue resistance.
Steel of the present invention is mainly used in the hot stamping die of low-alloy high-strength steel, also can be used for aluminium alloy hot-extrusion die.Steel of the present invention has good comprehensive mechanical property, higher thermal fatigue resistance and good thermostability and hot strength, simultaneously steel carbon of the present invention and alloying element content lower, production cost is low, and preparation section is simple, has good using value.
