Description
Technical field
The invention belongs to stainless steel applied technical field, more particularly to a kind of stainless compound steel plate.
Background technology
In recent years, as the demand to industrial equipment and works, durability, long lifetime and freedom from repairs are aimed at,
Stainless steel attracts attention as the material for meeting these demands.On the other hand, as stainless steel primary raw material with Ni,
There is the rise of price or the variation of price for the alloying element of representative in Mo, Cr.Therefore, it is dirty recently as entirety (No are replaced)
Stainless steel, can economically utilize the excellent corrosion resistance of stainless steel, price steadiness and cheap steel, stainless steel
Clad steel attracts attention.Stainless steel composite be using the stainless steel as composite with as mother metal common iron both
Steel obtained from the different metal laminate of property.Clad steel by will not same metal carry out metallography engagement and obtain, with
Plating is different, it is not necessary to worry to peel off, and can have the new features that can not be realized by single metal and alloy.So, for not
Become rusty for steel clad steel, the usage amount of stainless steel material less can also, and be able to ensure that and (refer to integral material as whole
Thickness for the stainless steel of composite material) equal corrosion resistance, therefore with economy can be taken into account and functional
Advantage.
According to the above, stainless steel composite is considered as the feature steel being highly profitable, and in recent years, its demand exists
Various industrial fields are increasingly improved.Stainless steel composite is particularly being used in marine structure, sea water desalting equipment, with floating body
Equipment (hereinafter referred to as " FPSO ", FPSO are unloaded in the storage of formula offshore oil/gas generation：Floating Production,Storage
And Offloading system) etc. in the case of in the various uses such as shipbuilding field of representative, due in harsh seawater
Used under corrosive environment, therefore it is required that resistance to corrosion seawater.
The passivation envelope of stainless steel is easily chlorinated thing ion damaged, and its forms of corrosion uses spot corrosion (Pitting
Corrosion) or crevice corrosion (Crevice Corrosion) mode.On the other hand, it is being with sulfuric acid, hydrofluoric acid etc.
In the acid of representative, forms of corrosion is in general corrosion, is in the seawater local corrosion on the other hand.Therefore, as preventing local corruption
The characteristic of the starting point of erosion, the consideration to pitting corrosion resistance becomes of crucial importance.
The pitting corrosion resistance of stainless steel is generally with spot corrosion index：Cr (quality %)+3.3Mo (quality %)+16N (quality %) is whole
Reason, spot corrosion index is higher, then pitting corrosion resistance is more excellent.But it is possible to which being only limitted to implement using the situation of spot corrosion index makes analysis
Go out the overall stainless steel of the heat treatment of the solid solutions such as thing, it is impossible to be directly applied to as stainless with the composite of carbon steel
In the pitting corrosion resistance of the composite of steel clad steel.
For stainless steel composite, generally to ensure that the engineering properties such as the intensity of mother metal, toughness and after normalizing
Use, so-called normalizing refers to be heated to 850~950 DEG C of temperature range, then carries out air cooling.Stainless steel is by unsuitable
During the thermal history of the heat affected zone caused by heat treatment, welding etc, corrosion resistance is significantly reduced sometimes.One of its reason exists
In, for stainless steel, in the thermal history by the heat affected zone caused by unsuitable heat treatment, welding etc, carbon
The equal intermetallic compound of compound, σ can be separated out.Thermal history suffered by clad steel changes because of the thickness of slab of clad steel, particularly
For more than 30mm clad steel, cooling velocity reduction, the equal intermetallic compound of carbide, σ is easier to separate out.
Prior art discloses following technology：In order to prevent at the normalizing for ensuring the engineering properties of mother metal and carrying out
The corrosion resistance of clad steel is deteriorated in reason, the composition of composite is provided, thus, even if to the austenite of composite
It is the normalized treatment that stainless steel implements 850~950 DEG C, can also keeps excellent corrosion resistance.However, for being obtained by this method
For the corrosion resistance of the stainless steel composite arrived, the corrosion rate in iron chloride corrosion test is about 2g/m2 hours, is made
For resistance to corrosion seawater and insufficient.
In addition, prior art also discloses following method：Provide the composition of solutionizing heat treatment condition and mother metal carbon steel, system
Make using the excellent stainless steel of sea water resistance as composite and the stainless steel composite pipe of mother metal is used as using carbon steel.However, specially
In sharp document 2, in order to ensure the corrosion resistance required by each purposes (such as marine structure) of stainless steel composite pipe and
Resistance to corrosion seawater, it is necessary to the stainless steel that composite is used is selected as according to each purposes.That is, only disclose only
The method being adjusted using the composition of stainless steel, in the case of stainless steel composite, it is difficult to improving to joint interface
The performance (corrosion resistance and mechanical property) of mother metal and composite is maintained while the reliability of integrity (zygosity).Separately
Outside, it is more difficult to the whole senior steel of reply and a variety of kinds.
