The present invention select nitrogenous low-nickel austenitic stainless steel as substrate, in substrate composition designs:
C (carbon): carbon is strong austenite former, can replace nickel to a certain extent, promotes austenitic formation, and stable
Austenite structure, can improve stainless intensity simultaneously.But when carbon content is too high, carbon is formed at crystal boundary after being combined with chromium
Chromium-rich carbide, causes intercrystalline corrosion；It addition, the chromium-rich carbide formed also reduces the impact flexibility of steel.Too low carbon content
By the difficulty increased in preparation process and cost.Therefore, designing carbon content in substrate rustless steel of the present invention is 0.03～0.10%.
Si (silicon): silicon for deoxidation, therefore, contains the silicon of more than 0.2% in fusion process in general rustless steel.But
The dissolubility of nitrogen will be reduced when silicone content is too high.Therefore, designing silicone content in substrate rustless steel of the present invention is 0.2～1.0%.
Mn (manganese): manganese is more weak austenite former, but be that strong austenite structure is stable in rustless steel
Element, and nitrogen dissolubility in steel can be improved.In low nickle type austenitic stainless steel, manganese and the elements compounding such as carbon, nitrogen in steel
Effect, part replaces nickel, it is ensured that rustless steel is at room temperature austenite structure.But the corrosion resistance of austenitic stainless steel is had by manganese
Negative effect.Therefore, Fe content of the present invention controls is 6.0～8.5%.
Cr (chromium): chromium is most important alloying element in rustless steel, is to obtain rustless steel rustless property and corrosion proof guarantee.
Owing to chromium is the element being obviously enhanced decay resistance, for ensureing good corrosion resistance, substrate rustless steel of the present invention designs chromium
Content is more than 16.0%.But, chromium is main ferrite former, and too high chromium will be difficult to ensure that substrate obtains room temperature
Austenite structure.Therefore, in substrate rustless steel of the present invention, chromium content controls is 16.0～18.0%.
Ni (nickel): nickel is to form element mutually most important with stable austenite, is to ensure that the crucial material of low-temperature flexibility simultaneously
Material.In substrate rustless steel of the present invention, nickel content controls, 1.5～3.0%, to ensure that material has lower cost, to guarantee steel simultaneously
There is under the austenite structure under room temperature and low temperature the impact flexibility with excellence；And if nickel content is less than 1.5%, then without
Method meets the present invention requirement to low-temperature impact toughness.
Mo (molybdenum): molybdenum is the important element improving decay resistance in rustless steel, and its mechanism is stable passivating film and promotion
The enrichment in passivating film of the chromium element, molybdenum can also improve pitting resistance, therefore, the master of molybdenum further with nitrogen synergism
Act on is to improve corrosion resistance.But the too high cost of alloy that will increase of molybdenum content, the molybdenum content control in substrate rustless 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 improve stainless plasticity, but copper content
Hot-working character it is unfavorable for time too high.Therefore, in substrate rustless steel of the present invention, copper content control is 1.5～3.0%.
N (nitrogen): nitrogen is the element very strongly forming, stablize and expand austenitic area in rustless steel.Nitrogen is stainless
In steel except can substitute precious resource such as nickel in addition to, it is also possible on the premise of significantly reducing material plasticity and toughness, bright
The aobvious intensity improving material, moreover it is possible to improve stainless resistance to spot corrosion performance.But when nitrogen content is too high, nitrogen containing metal will be increased
Between the risk that formed mutually, improve melting and hot worked difficulty simultaneously, cause being difficult to produce.Therefore, substrate rustless steel of the present invention
In Control of Nitrogen Content be 0.10～0.25%.
P (phosphorus): phosphorus is considered harmful element in substrate rustless steel, should control the lowest more good as far as possible.
S (sulfur): higher in view of Fe content in substrate rustless steel, easily forms MnS field trash, affects corrosion resisting property, with
Time in view of the sulfur impact on welding pool mobility, it is therefore desirable to control sulfur content 0.001～the level of 0.01%.
It should be noted that chromium, manganese, the content of three elements of nitrogen must add in collaborative design in substrate rustless steel of the present invention
Add.In order to make nitrogen have enough solid solubility in steel, it is necessary for adding a certain amount of chromium, manganese element, but stable in order to ensure
Austenite structure, chromium content can not be the highest.Chromium equivalent and nickel equivalent is used to carry out reference, wherein, chromium equivalent Creq=%Cr+%
Mo+1.5%Si, nickel equivalent Nieq=%Ni+30%C+30%N+0.5%Mn+0.25%Cu.By calculating Creq and Nieq,
The output control coordinating Schaeffler-Delong rustless steel organization charts make the volume fraction of ferritic phase within 4%, with
Guarantee that material has preferable hot-working character and stable austenite structure.Therefore, substrate rustless steel Ni content in the present invention
After reduction, it is necessary to properly increase N content to guarantee to obtain stable austenite phase tissue.
It addition, in order to ensure that composite plate has excellent cold-forming property, substrate and the design of compound plate composition and guarantees Md30/50
(α ') below 20 DEG C, wherein, Md30/50(α ')=580-520C%-2Si%-16Mn%-16Cr%-23Ni%-300N%-
26Cu%-10Mo%.As substrate, compound plate composition control Md30/50(α ') is too high, easily produces during room temperature cold deformation
Strain-induced martensite tissue, thus affect the stability of Deformation structure.It is cold in the room temperature of deflection≤20% that the present invention controls material
The course of processing will not produce magnetic, it is ensured that excellent cold-forming property.
