Description
Technical field
The invention belongs to Hardware fitting technical field, relate to a kind of slider bar.
Background technology
Slider bar is a kind of conventional Hardware fitting, and widely, the Main Function of slider bar is exactly will to its range of application
If stem structure or parts link together, and when bearing component movement, need moment of torsion or the active force of transmission.
The firm material of rustless steel that common slider bar use is general, and meeting stress during the use of slider bar, therefore can
Various mechanical properties to slider bar, such as yield strength, tensile strength, percentage elongation etc. all can have the requirement that comparison is high, and
The material of slider bar is typically all stainless steel material at present, and the use environment of slider bar is typically relatively more severe, often contacts
Steam, also can touch the environment of acidity or alkalescence, the most in this environment, can corrode slider bar, reduces and slides
Thinking of rod can, it is possible to also can cause security incident, therefore, it is necessary to it is preferable and erosion-resisting to improve a kind of mechanical property
Slider bar, solves the technical problem that presently, there are.
Summary of the invention
For problem above, the invention provides a kind of slider bar, there is more preferable mechanical property, and corruption can be resisted
Erosion, adapts to various acid or alkali environment.
The technical scheme is that a kind of slider bar, co-penetration layer is contained on slider bar surface, including:
Barred body: offer screwed hole on the top end face of described barred body, one end of the corresponding described screwed hole of described barred body is offered
Having holes for clamping, described holes for clamping connects with described screwed hole and both axis are mutually perpendicular to；
Pinching screw: pinching screw is arranged in described holes for clamping；
Clip: described hoop sleeve is on described barred body and it is connected with described pinching screw, when described clip tightens up, its
Described pinching screw is pressed to described screwed hole；
Wherein, described slider bar is grouped into by the one-tenth of following percentage by weight: C:1～1.2, Si:0.8～1, Mn:0.7～
0.9, P:0.012～0.015, S:0.04～0.06, Cr:16～18, Ti:0.23～0.3, Nb:0.3～0.7, Mo:0.5～
0.6, Ce:0.1～0.2, La:0.1～0.2, surplus is Fe.
Further, the end of described barred body offers a circle scrobicular ring, and described scrobicular ring and described holes for clamping are positioned at described rod
On the sustained height position of body, described clip is arranged in described scrobicular ring.
Further, the termination of the corresponding described screwed hole of described pinching screw is provided with elastic conflict block.
Further, the end face edge of described barred body is provided with chamfering.
The slider bar material of the present invention controls the content of alloying element further, by adding Nb and Ti element, and controls
Its content, ensureing to be formed ferritic while, improves solution strengthening and precipitating reinforcing effect, simultaneously by adding Mo element also
Controlling its content, while ensureing toughness, the Mo of trace can strengthen the stability of Fe surface film oxide, improves spot corrosion electricity
Position, strengthen material in corrosive medium, the especially corrosion resistance in the environment having halogen.
Rustless steel in use can run into the compound of C and N and Cr and separate out on the surface of crystal boundary, causes crystal boundary weak, no
But corrosive nature can be reduced, also can reduce mechanical property, by adding Nb and Ti, the precipitated phase of formation Ti (CN), and due to
Being added on crystal grain and crystal boundary of Nb and Ti defines TiN, NbC and Fe2Nb precipitated phase, and this precipitated phase relative intensity is high, with
Time can improve tensile strength and the hardness of material due to the Joint effect of solution strengthening and precipitation strength, owing to decreasing carbon nitridation
The precipitation of chromium, also can strengthen anti-corrosion effects.
Owing to Fe is that the most active metals can form oxide-film on surface, the existence of oxide-film originally can strengthen Fe
Decay resistance, but, owing to there will be halogens in air, the existence of such as Cl ion, when corrosion of metal point position is high
In marginal value i.e. pitting potential when, can be formed and puncture, chloride ion etc. is it is possible to puncture skin covering of the surface to cause the generation of spot corrosion core
Spot corrosion core, and the existence of spot corrosion core can greatly speed up corrosion of metal speed, point and face can cause the corrosion of entirety, adds Mo
After element, the stability of film can be improved, make stainless steel surfaces generate the finest and close and firm passivating film.Increase point with molybdenum content
Erosion current potential improves rapidly.Steel, in halogenic medium, increases with molybdenum content in steel, and corrosion rate quickly reduces, therefore in rustless steel
Add molybdenum and can improve the performance of the anti-spot corrosion of steel.Thus be greatly increased the decay resistance of material, but if Mo element addition
Improper, ferritic formation can be hindered, reduce the mechanical property of material, it is therefore necessary to the content of Mo element is controlled accurately
System.
Ce and La existence form in carbon junction steel has rare-earth sulfide, between rare-earth oxide sulfate, solid solution and rare earth metal
Compound, wherein rare-earth sulfide, solid solution and the unstable chemcial property of rare earth intermetallic compound, be situated between very soluble in corrosion
In matter, discharge Rare-Earth Ce3+Or La3+And cathode zone precipitation thus slow down the carrying out of corrosion.Carbon junction steel adds rare earth make
Steel corrosion current potential is negative to be moved, and corrosion current density reduces, and cathode reaction is hindered, and corrosion resisting property is improved, and adds in steel
Rare earth element serve the effect of cathodic corrosion inhibitor.Along with its rusty scale thickness of increasing of content of rare earth reduces and caused.Electricity
Lotus transfer resistance is directly related with the corrosion rate of steel matrix, and the increase of charge migration resistance shows the increasing along with content of rare earth
Adding, the extent of corrosion of steel matrix alleviates, and corrosion resisting property is improved.Ce and La adds in steel, and with P, Cu, Si occur phase interaction
With, contribute to forming fine and close, continuous, thick and that adhesion the is good compound iron rusty scale containing Si-Cu rare earth spinel-type, thus improve
Its atmospheric corrosion resistance.
