To this end, the invention relates to the use of a precipitation-hardenable, martensitic, stainless chromium-nickel steel having the following composition (in weight %): 10 to 14 of chromium; 7 to 11 of nickel; 0.5 to 6 of molybdenum; 0.5 to 4 of copper; 0.05 to 0.55 of aluminium; 0.4 to 1.4 of titanium; up to 0.3 of carbon and nitrogen; less than 0.05 of sulphur; less than 0.05 of phosphorus; up to 0.5 of manganese; up to 0.5 of silicon; respectively up to 0.2 of tantalum, niobium, vanadium and wolfram; and optionally up to 9 of cobalt; optionally 0.0001 to 0.1 of boron; the remainder consisting of iron and common impurities.
Description
Technical field
The present invention set forth can precipitation-hardening Martensite Stainless Steel be used to make a kind of novel use of throw, this instrument has very high requirement to the combination and the solidity to corrosion of high rigidity and ductility, for example be to manufacture boring, milling, grinding and cutting tool.
Background technology
The martensitic precipitation hardening stainless steel has been known to the public in WO93/07303, has wherein described a kind of stainless composition, and this stainless steel has very high intensity, simultaneously, has good ductility again.This steel are described is that the most suitable making injection cannula, dental instrument and medicine equipment, starting material are wire rod and bands of being made by the steel of mentioned kind.Because this steel grade has high hardness, so further processing will be limited in minimum degree.
Described a kind of technology in WO01/14601 A1, be used to make the parts with complex geometric shapes, this technology comprises a series of step: precipitation-hardening, annealing is quenched and sclerosis.Consequently uniform rigidity reaches 450HV at least.People learn by example, and according to this specific technological process precipitation-hardening, Martensite Stainless Steel can be used to make medicine equipment.By means of special machining process, in this case, the problem of workability has obtained solution, but it can't be used for tools, particularly can not make the throw with complex geometric shapes.
After must being met, could make a series of final condition the throw of mechanical handling of a kind of steel, therapeutic medical especially throw, especially dentistry and surgical instruments.
Boring, milling, grinding and cutting tool have very little diameter according to its purposes, may be less than 1mm.It is then oversize that but its length is compared with its diameter, can reach specific working depth like this, and because cutter will be placed in anchor clamps or the chuck cover, therefore, its length has further increased again.Because this extreme length/diameter ratio and the unfavorable distribution of torque that causes therefrom, therefore, this instrument is very responsive for the bending load that is applied in the practical application.The slight curvature of drill bit, even the almost invisible bending of bore hole, in the time of also can causing making arrangements for surgery or use time action inaccurate and uneven next time next time.Since continually and hypervelocity ground rotate, this will cause the intra-operative drill bit to rupture in the practice.This means that drill bit is the life-span weak point not only, must often change for the sake of security, and patient, patient and onlooker are also had great danger, hit, also have sizable cost factor because they may fly over the cutter fragment that comes.
According to the medical product method, the manufactured merchant of the instrument that size is especially little is called disposable products, and this shows the expense that has increased the user.Instrument no longer allows to use for the second time once use.The user must use a new instrument, and this has caused irrational high cost.
Therefore, people require to have or do not have the throw that the machine of the cutting edge of regulation is handled forwardly, can be used for dentistry and surgery boring, milling, grinding and bite prodigiosin especially multiple use is arranged, these instruments all have very high hardness, corrosion-resistant, compare simultaneously their also anti-fractures with known instrument or apparatus.Except hardness and resistance to fracture, moment erosion resistance also be vital.Dentistry and surgical instruments are each all will disinfect after using, and these apparatuses are exposed in the environment of heavy corrosion (temperature, moisture content, organism and other solvent etc.) easily.In addition, also have many corrosion media between the usage period,,, then exist patient's danger of residual contaminants that is corroded, and suffer from dangerous post-operative complication easily if these dentistry and surgical instruments are damaged or are subjected to corrosive invasion and attack such as blood, body fluid.
Therefore, the throw that needs a kind of machine stable, corrosion-resistant and bio-compatible to handle forwardly is such as boring, milling, grinding and cutting tool.It has intensity values simultaneously and is combined with the good ductility performance.
At present, a large amount of known and proof several alloys have been used to shape and make such instrument and apparatus.Some metals wherein are Martensite Stainless Steels, austenitic stainless steel precipitation-hardening stainless steel.In these alloys each all has a series of good material performance, and such as erosion resistance, intensity, formability and/or ductility, but every kind of alloy also has shortcoming, and can not satisfy the certain products requirement.The challenge of the shortcoming of the throw that can buy and existence is well-known in practice in the market.Indicate the chemical ingredients of some steel grades that often use in the following table.
