Description
Technical field
The present invention relates to a kind of simple steel flange of good corrosion resistance.
Background technology
Mild steel annealed structure is ferrite and a small amount of pearlite, its intensity and hardness lower, plasticity and toughness better.Therefore, its cold formability well can adopt the methods such as crimping, bending, punching press to carry out cold forming.This steel have good weldability.The mild steel hardness that carbon content is very low is very low, and machinability is not good, and normalized treatment can improve its machinability.
Mild steel has larger timeliness tendency, and existing quench aging tendency, also has strain ageing tendency.When steel comparatively fast cools from high temperature, ferrite scrapes carbon, nitrogen supersaturation, and it also can form the carbon nitrogen thing of iron lentamente at normal temperature, and thus the intensity of steel and hardness improve, and plasticity and toughness reduce, and this phenomenon is called quench aging.Even if mild steel does not quench and air cooling also can produce timeliness.Mild steel produces a large amount of dislocation through deformation, and from carbon, nitrogen-atoms and dislocation generation elastic interaction in ferrite, carbon, nitrogen-atoms are gathered in around dislocation line.The combination of this carbon, nitrogen-atoms and dislocation line claims a year old KESHI gas mass (Ke Chuier air mass).It can make the intensity of steel and hardness improve and plasticity and toughness reduction, and this phenomenon is called strain ageing.There is larger harmfulness than quench aging to the plasticity of mild steel and toughness during deformation, the stress strain curve of mild steel has significantly upper and lower two yield points.Occur, until surrender extends end, occurring the surface ruffle band formed due to inhomogeneous deformation at specimen surface, being called luders band from upper yield point.Therefore many stamping parts are often scrapped.Its prevention method has two kinds.A kind of high pre-Deformation Method, also can produce luders band during punching press after a period of time placed by the steel of pre-deformation, the steel of therefore pre-deformation before the punching standing time unsuitable long.Another kind adds aluminium or titanium in steel, makes itself and nitrogen form stable compound, prevents the strain ageing that formation KESHI gas mass causes.
Summary of the invention
The invention provides a kind of simple steel flange of good corrosion resistance with high leakproofness, long service life, corrosion-resistant and intensity high advantage.
Technical scheme of the present invention is: a kind of simple steel flange of good corrosion resistance, the simple steel flange of described good corrosion resistance comprises the electrodeposited coating of the superiors, corrosion resisting alloy layer and the undermost low carbon steel layer in intermediate layer combine, described electrodeposited coating is chrome plating, described corrosion resisting alloy layer is ferrous alloy, described electrodeposited coating accounts for the 7%-12% of the overall component of simple steel flange of good corrosion resistance, described corrosion resisting alloy layer accounts for the 46%-48% of the overall component of simple steel flange of good corrosion resistance, described low carbon steel layer accounts for the 40%-46% of the overall component of simple steel flange of good corrosion resistance.
In a preferred embodiment of the present invention, described low carbon steel layer comprises manganese, vanadium, titanium, niobium.
In a preferred embodiment of the present invention, described electrodeposited coating accounts for 7% of the overall component of simple steel flange of good corrosion resistance, described corrosion resisting alloy accounts for 48% of the overall component of simple steel flange of good corrosion resistance, and described low carbon steel layer accounts for 45% of the overall component of simple steel flange of good corrosion resistance.
The simple steel flange of a kind of good corrosion resistance of the present invention, has high leakproofness, long service life, the advantage that corrosion-resistant and intensity is high.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Wherein, the simple steel flange of described good corrosion resistance comprises the electrodeposited coating of the superiors, the corrosion resisting alloy in intermediate layer and undermost low carbon steel layer and combines, described electrodeposited coating is chrome plating, described corrosion resisting alloy layer is ferrous alloy, described electrodeposited coating accounts for the 7%-12% of the overall component of simple steel flange of good corrosion resistance, described corrosion resisting alloy layer accounts for the 46%-48% of the overall component of simple steel flange of good corrosion resistance, and described low carbon steel layer accounts for the 40%-46% of the overall component of simple steel flange of good corrosion resistance.
Further illustrate, described low carbon steel layer comprises manganese, vanadium, titanium, niobium, described electrodeposited coating accounts for 7% of the overall component of simple steel flange of good corrosion resistance, described corrosion resisting alloy layer accounts for 48% of the overall component of simple steel flange of good corrosion resistance, and described low carbon steel layer accounts for 45% of the overall component of simple steel flange of good corrosion resistance.Chrome plating chrome plating is cathodic electrodeposition coating to steel-iron components.It has higher heat resistance, and under normal temperature, hardness is good, and wearability is good, and light reflective is strong, is widely used in the wearability of raising part, light reflective and repairs the aspect such as size and decoration.
Further illustrate, ferrous alloy is the class that in hard material, use amount is large and wide again, and the maximum feature of this kind of material is that combination property is good, and serviceability limitation is very wide, and material price is cheapest.Main hardening element is Cr, and also have the intensified elements such as Si, Mo, Mn, V, W, alloying element total amount is no more than 10%.Coating structure is low-carbon martensite, has good machinability, coating hardness HRc3054, and impact flexibility is fabulous, also has good proof stress fatigue and cold-heat fatigue property.Its material makes wire and tubular filament submerged arc overlay welding, and welding performance is better, not easy to crack.Typical use is the part of the unlubricated rolling of intermetallic or slip.As Heat Working Rolls, backing roll, caster roll, Roll Collar, alignment roller and excavator roller etc.Also have good resistance to corrosion, Typical Representative is Ti; Zr; Ta etc.; Wherein most typical representative is Ti; Titanium material has a wide range of applications, and is mainly used in the corrosive environment that some stainless steels cannot adapt to.The corrosion-resistant principle of titanium material: in oxidizing atmosphere, forms fine and close oxide-film and provides protection; So generally can not be used in comparatively strong or that the higher corrosive environment of sealing of reproducibility (anaerobic environment), meanwhile, the application of temperature of titanium material is generally less than 300 degrees Celsius.It is to be particularly noted that active metal all can not be used for fluorine-containing environment.The invention provides a kind of simple steel flange of good corrosion resistance, there is high leakproofness, long service life, the advantage that corrosion-resistant and intensity is high.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
