Specific embodiment
The exemplary embodiment for embodying feature of present invention and advantage will describe in detail in the following description.It should be understood that
The present invention can have various variations in different embodiments, neither depart from the scope of the present invention, and theory therein
Bright and diagram inherently is illustrated as being used, rather than to limit the present invention.
The present invention provide it is a kind of by stainless steel composite plate texture at tank body and with the tank container of the tank body,
In, tank body can be connected with frame in the prior art and form tank container.
Refering to fig. 1, the structure type of tank body 1 is common structure, mainly by cylinder 11 and the envelope for being set to 11 both ends of cylinder
First 12 form the structure with internal storage space.Based on the preferred embodiment of the present invention, cylinder 11 and end socket 12 be not respectively by
Rust steel composite board 10 is made, and rear cylinder body 11 and end socket 12 weld.
Referring to Fig.2, stainless steel clad plate 10 can be double-layer structure, by one layer of base 101 and it is located at 101 inner surface of base
One layer of cladding 102 constitute.Wherein, reference is in the space that is enclosed using tank body 1 of orientation of "inner", "outside", similarly hereinafter.That is: stainless
After steel composite board 10 is made as tank body 1, base 101 is the outer layer of tank body 1, is in contact with external environment；Cladding 102 is tank body 1
Internal layer, the medium shipped with the inside of tank body 1 is in contact.
Referring again to Fig. 3, stainless steel clad plate 10 can also be three-decker, by one layer of base 101 and be located at base
Two layers of cladding 102,103 of 101 the inner surface and the outer surface of layer is constituted.
In two kinds of structure types of above-mentioned stainless steel clad plate 10, cladding 102 (103) is integrally continuously coated on base
101 inner surface, or it is also coated on the outer surface of base 101 simultaneously.The material of base 101 is that nitrogenous low-nickel austenitic is stainless
Steel, the material of cladding 102 (103) are the austenitic stainless steel that corrosion resistance is higher than 101 material of base, for example, 316L, 316 or
304 type austenitic stainless steels etc..
According to the difference of each national standard, the title of the type austenitic stainless steel of 316L, 316 or 304 is also had nothing in common with each other.Wherein,
The corresponding approximate trade mark of 316L type stainless steel or code name include: S31603, and 1.4402,1.4404, SUS316L etc..316 types are stainless
The corresponding approximate trade mark of steel or code name include: S31600, S31608,1.4401, SUS316 etc..304 type stainless steels are corresponding close

In the stainless steel clad plate 10, the restriction of material (hereinafter referred to as " substrate ") above-mentioned constituent of base 101 is managed
By as follows:
C (carbon): carbon is strong austenite former, can replace nickel to a certain extent, and austenite is promoted to be formed, and is stablized
Austenite structure, while the intensity of stainless steel can be improved.But when carbon content is excessively high, carbon in conjunction with chromium after formed in crystal boundary
Chromium-rich carbide, leads to intercrystalline corrosion；In addition, the chromium-rich carbide formed also reduces the impact flexibility of steel.Too low carbon content
Difficulty and cost in preparation process will be increased.Therefore, it is 0.03~0.10% that carbon content is designed in substrate stainless steel of the present invention.
Si (silicon): silicon in fusion process be used for deoxidation, therefore, in general stainless steel containing 0.2% or more silicon.But
The solubility of nitrogen will be reduced when silicone content is excessively high.Therefore, it is 0.2~1.0% that silicone content is designed in substrate stainless steel of the present invention.
Mn (manganese): manganese is weaker austenite former, but is that strong austenite structure is stablized in stainless steel
Element, and solubility of the nitrogen in steel can be improved.In low nickle type austenitic stainless steel, the elements compoundings such as carbon, nitrogen in manganese and steel
Effect, part replace nickel to ensure that stainless steel is austenite structure at room temperature.But manganese has the corrosion resistance of austenitic stainless steel
Negative effect.Therefore, manganese content control is 6.0~8.5%.
Cr (chromium): chromium is most important alloying element in stainless steel, is to obtain stainless steel rustless property and corrosion proof guarantee.
Since chromium is the element for significantly increasing corrosion resistance, to guarantee good corrosion resistance, chromium is designed in substrate stainless steel of the present invention
Content is 16.0% or more.But chromium is main ferrite former, excessively high chromium will be difficult to ensure that substrate obtains room temperature
Austenite structure.Therefore, chromium content control is 16.0~18.0% in substrate stainless steel of the present invention.
Ni (nickel): nickel be to be formed with the mutually most important element of stable austenite, while be the key that guarantee low-temperature flexibility material
Material.But nickel is expensive, therefore, nickel content control is 1.5~3.0% in substrate stainless steel of the present invention, to guarantee that material has
Have lower cost, at the same ensure steel under austenite structure and low temperature at room temperature have excellent impact flexibility.
Mo (molybdenum): molybdenum is the important element that corrosion resistance is improved in stainless steel, and mechanism is to stablize passivating film and promotion
Enrichment of the chromium in passivating film, molybdenum can also act synergistically with nitrogen, further increase pitting resistance, therefore, the master of molybdenum
Act on is to improve corrosion resistance.But molybdenum content is excessively high will to increase cost of alloy, the molybdenum content control in substrate stainless steel of the present invention
It is made as 0.1~0.5%.
Cu (copper): copper is a kind of austenite former, and the addition of copper can be improved the plasticity of stainless steel, but copper content
It is unfavorable for hot-working character when excessively high.Therefore, copper content control is 1.5~3.0% in substrate stainless steel of the present invention.
N (nitrogen): nitrogen is very strongly formation, the element for stablizing and expanding austenitic area in stainless steel.Nitrogen is stainless
It, can also be bright under the premise of significantly reducing material plasticity and toughness in steel other than it can substitute precious resource such as nickel
The aobvious intensity for improving material, moreover it is possible to improve the resistance to spot corrosion performance of stainless steel.But nitrogen content it is excessively high when, nitrogen containing metal will be increased
Between the risk that is mutually formed, while improving melting and hot worked difficulty, cause to be difficult to produce.Therefore, substrate stainless steel of the present invention
In Control of Nitrogen Content be 0.10~0.25%.
P (phosphorus): phosphorus is considered as harmful element in substrate stainless steel, should try to control more lower better.
S (sulphur): in view of manganese content is higher in substrate stainless steel, MnS field trash easy to form influences corrosion resisting property, together
When influence in view of sulphur to welding pool mobility, it is therefore desirable to control level of the sulfur content 0.001~0.01%.
It should be noted that the content of three chromium in substrate stainless steel of the present invention, manganese, nitrogen elements must collaborative design add
Add.In order to make nitrogen there are enough solid solubility in steel, a certain amount of chromium, manganese element must be just added, but single in order to guarantee
Austenite structure, chromium content can not be too high.It is referred to using chromium equivalent and nickel equivalent, Creq (chromium equivalent)=%Cr+%Mo+
1.5%Si, Nieq (nickel equivalent)=%Ni+30%C+30%N+0.5%Mn+0.25%Cu.By calculating Creq and Nieq, match
The result for closing Schaeffler-Delong (She Fule-De Long) controls Phase Proportion, therefore substrate stainless steel Ni content in the present invention
After reduction, it is necessary to properly increase N content to ensure austenite phase tissue.
In addition, the stainless composition of steel of substrate is set in order to guarantee that stainless steel clad plate 10 has excellent good cold-forming property
