Description

A kind of novel 5CrW2SiBAlN impact resistant tools steel
Technical field
The present invention relates to a kind of impact resistant tools steel, specifically relate to a kind of impact resistant tools steel adding Mg, B, Al, N and nitride.
Background technology
Carbon tool steel basis adds alloying element and in the Notch Ductile Steel that formed, the measuring instrument steel of the conventional Chinese trade mark has 4CrW2Si, 5CrW2Si, 6CrMnSi2Mo1V etc.The instrument operated under being widely used in high impact loads, such as: the cutting unit that manual and pneumatic chisel, air hammer instrument, riveting tool, regeneration move, cold punching are cut out and trimming die; Hotwork instrument, as the transfer mold etc. of hot piercing and perforating tool, hot shearing mould, hot-forging die, fusible alloy.This steel has good intensity and hardness when high temperature, higher toughness is had after tempering, there are certain hardening capacity and high-temperature mechanics intensity, little to decarburization, strain cracking susceptibility during thermal treatment, but tungsten, molybdenum, vanadium are noble metal, and in smelting process, consumed energy is more, and add tungsten, molybdenum, vanadium make the quenching temperature of steel improve, be not low-carbon energy-saving product, moreover these metals are again scarcity strategic resource.
The present inventor finds through long-term large quantity research, test, observation, the impact resistant tools steel of Mg, B, Al, N and nitride (BN, AlN and/or TiN) of adding low melting point effectively can improve wear resistance and the intensity of steel, the performances such as the intensity of 5CrW2Si are not only made to improve, excellent mechanical property also reaches middle chromium cold work die steel in high alloy through (code name LD), not only widen use range, also more economical, environmental protection, to have economized on resources.
Summary of the invention
The object of the invention is, a kind of in impact resistant tools steel 5CrW2Si, add low melting point Mg, B, Al, N and nitride are provided, increase substantially the alloy tool steel of wear resistance and intensity,
In technical scheme of the present invention: add low melting point Mg, B, Al, N and nitride in impact resistant tools steel 5CrW2Si, but not containing the oxide impurity of these compounds, not only S≤0.008% and P≤0.03%, and oxide aggregate O≤0.005%.
Magnesium: while the oxidation-resistance improving steel, low melting point metal Mg makes it forge in heat-processed in annealing, the binary alloy that the Mg metal of separating out and the element such as harmful low melting point Sn, Pb, As, Sb, Bi of matrix coherence are formed becomes the intermetallic compound of higher melt, changes size and the form of low melting point element simultaneously.
Aluminium: can refinement steel as-cast structure, reduce the brilliant spacing arm of little skill.More effectively stop Austenite Grain Growth by the size and distribution that change carbide, residual austenite can be promoted to martensitic transformation, improve tempered-hardness, reduce tempering temperature.When loss in toughness is little, improve bending strength and the wear resistance of steel.There is good antioxidant property simultaneously.
Boron: be conducive to the r-a phase transformation suppressing steel, significantly suppress pearlitic formation, improve the content of bainite, while the substructure of refinement bainite, improve intensity and keep good low-temperature flexibility.Add appropriate boron in steel, steel creep rupture life at high temperature can be increased, and improve over-all properties and the hardening capacity of steel.
Nitride: to be added in austenitic steel and mainly to improve its intensity and solidity to corrosion, and in Hi-Stren steel, nitrogen is also by as micro alloying element, and by forming microalloying carbon, nitride plays strengthening effect.Nitride in steel has higher stability than carbide, the tiny M(C.N of disperse in precipitated phase) raising of type nitride strengthening successful.The Carbonitride Precipitation forming disperse after tempering promotes secondary hardening mutually, to the function even during some amount with three underhardenings.
Nitrogen: be present in matrix with the form of interstitial solute atom, has crystal grain thinning, produces solution strengthening and shortens Secondary Dendrite Arm Spacing, reduces grain segregation, improves inclusion distribution, improves the physical strength of steel, improves the function of impelling strength and wear resistance.Solid solution state nitrogen, can reduce the solid matter imperfect dislocation in austenite, and restriction is containing the dislocation motion of interstitial impurity atomic group, and strengthening effect is stronger than carbon.Solid solution nitrogen is similar to the effect of carbon, nickel, can expand r mutually and make stabilization of austenite.Solid solution nitrogen can improve the hardening capacity of material, and under same quenching technology, quench-hardened case is darker, makes the improvement that core tissue obtains to a certain degree simultaneously.There is short range order in nitrogen-atoms, do not need long distance diffusion, be easy to first separate out (FeCr) 2N in residual austenite; Tempering temperature can be reduced.
Tungsten: Main Function is the red hardness high temperature oxidation resistance that can improve steel, and can improve the wear resisting property of steel, tungsten of the present invention is applicable to 2.0 ~ 3.0.
It is few that 5CrW2Si impact resistant tools steel also exist alloying element, the shortcoming of wear resistance intensity difference, and be significantly less than middle chromium cold work die steel in high alloy through (code name LD) work-ing life.After smelting 1 ~ 3 ton of intermediate frequency, add after Mg, B, Al, N of low melting point and the steel alloy of nitride through secondary smelting, through forging, annealing, Quench and temper process, work-ing life improves more than 5 times than traditional 5CrW2Si impact resistant tools steel.
The object of this invention is to provide a kind of 5CrW2SiBAlN impact resistant tools steel of improvement, except being otherwise noted, amount described in the application is mass parts meter.
