Description
Technical field
Stainless steel bars technical field is the utility model is related to, specially a kind of super austenitic stainless steel composite bar.
Background technology
With the high speed development and scientific and technological progress of national economy, the application of stainless steel bars is increasingly extensive, right
The requirement of stainless steel tube also more and more higher, in order that stainless steel bars meets that the use of every field will on quality and quantity
Ask, have fast development in terms of the exploitation of new steel grade both at home and abroad；China's stainless steel is in technology, equipment, product matter
Amount etc. still has larger gap, it is necessary to constantly research and development, technological transformation and raising be carried out, to adapt to state with international most advanced level
The requirement of people's economic development；Stainless steel bars is widely used to every field at present：Automotive industry, water and wastewater industry, environmentally friendly work
Industry, industrial plants, household electrical appliances industry, dosage it is bigger mainly austenitic stainless steel, with advances in technology with production
Need, from raw material resources and material cost and reach physics and chemistry and mechanical property requirements angle be required for constantly developing it is new
Stainless steel.Occur deformation, corrosion phenomenon after the use of stainless steel bars product long-time in the prior art, service life is short.
Utility model content
The purpose of this utility model is to provide a kind of super austenitic stainless steel composite bar, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides following technical scheme：A kind of super austenitic stainless steel compound bar
Material, including stainless steel bars body, the compound Withstand voltage layer in stainless steel bars outer body face, complex copper on the outside of the Withstand voltage layer
Nickel alloy layer, the copper-nickel alloyed layer coat one layer of protective coating.
Preferably, the stainless steel bars body material uses 06Cr17Ni12Mo2Ti austenitic stainless steels.
Preferably, the Withstand voltage layer uses 17CrNiMo carbon steel materials.
Preferably, the protective coating uses Hastelloy hot-spraying coating.
Preferably, the protective coating thickness is 1mm-2mm.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, low manufacture cost,
With superior corrosion resistant, pressure-resistant, high temperature resistant, performance is unlikely to deform, and there is high tenacity and plasticity, it is possible to increase the use of product
Life-span.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of super austenitic stainless steel composite bar, bag
Include stainless steel bars body 1, the compound Withstand voltage layer 2 of the lateral surface of stainless steel bars body 1, the outside complex copper of Withstand voltage layer 2
Nickel alloy layer 3, the surface of the copper-nickel alloy-layer 3 coat one layer of protective coating 4；The material of stainless steel bars body 1 uses
06Cr17Ni12Mo2Ti austenitic stainless steels；06Cr17Ni12Mo2Ti austenitic stainless steels have comprehensive and well comprehensive
Close performance；Albata layer can significantly improve intensity, corrosion resistance, hardness, resistance and pyroelectricity, and reduce resistivity temperature system
Number；Withstand voltage layer 2 uses 17CrNiMo carbon steel materials；17CrNiMo carbon steel materials hardness is high, and it is whole can further to improve bar
The compressive property of body.
In addition, in the present embodiment, protective coating 4 uses Hastelloy hot-spraying coating；The thickness of protective coating 4 is 1mm-
2mm.Hastelloy has extremely strong etch resistant properties under the conditions of various severe corrosives, is typically widely used in strong corrosive media
In, particularly high temperature resistance strong acid media corrosive nature seems more superior, can effectively improve the decay resistance of bar.
The utility model is simple in construction, low manufacture cost, has superior corrosion resistant, pressure-resistant, high temperature resistant, being unlikely to deform property
Can, and there is high tenacity and plasticity, it is possible to increase the service life of product.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
