The invention of the disclosed material is disclosed. However, generally, simply increasing the Cr or Ni content of the Fe-based alloy or the Ni-based alloy does not provide a sufficient carburizing suppression effect, and it is necessary to further suppress metal dusting. is there.
- Japanese Unexamined Patent Publication No. Hei 11-11772 473 is designed to prevent corrosion of “high-temperature alloys” containing iron, nickel and chromium by metal dusting.
- one or more metals of Groups 8, 1B, 4 and 5 of the Periodic Table of the Elements and their mixtures are attached to surfaces by conventional physical or chemical means.
- This is a technology that forms a thin layer with a thickness of 0.01 to 10 ⁇ by annealing in an active atmosphere.
- thin layers such as Sn, Pb, and Bi.
- this method is effective initially, it will not be effective if the thin layer is peeled off after long-term use.
- An object of the present invention is to provide a high corrosion resistance having excellent corrosion resistance in an environment in which metal dusting occurs and in a gaseous atmosphere containing H 2 , CO, CO 2 , H 2 O, hydrocarbons and the like.
- An object of the present invention is to provide a metal material that is a high Ni—Fe alloy, a multi-layer metal material, and a metal tube made of them.
- the gist of the present invention is as follows.
- V A multilayer metal pipe whose material is the multilayer metal material described in the above (EO) and whose outer surface is a layer of a metal material having metal dusting resistance.
- the components of the following group (a) instead of part of Fe, the components of the following group (a) must be used. At least one of them should be included. In this case, the high temperature strength can be increased.
- the element symbol in the formula is expressed as fn 2 If the value is 0.003 or more, even better metal dusting resistance is secured.
- At least one of the components of the group (b) shown below is used instead of part of Fe. It is preferable to contain one or more kinds.
- the present inventors have conducted various studies on metal materials having excellent resistance to a corrosion phenomenon called metal dusting that occurs at a relatively low temperature.
- the occurrence of metal dusting is affected by the protection of the oxide film formed on the surface and the development of the carburized layer formed inside the oxide film. In other words, if the oxide film cracks or the oxide film peels, C penetrates into the metal to form a carburized layer, and metal dusting is likely to occur due to volume changes at that time and the formation and decomposition of carbides. . Therefore, we examined the composition of the metal material to improve the protection of the oxide film and to suppress the growth of the carburized layer.
- the intrusion of C into the metal material is considerably suppressed.However, it is necessary to completely block the intrusion of C, in other words, the oxide film does not crack at all for a long time and peels off It is impossible to do what is not. Therefore, it is indispensable to suppress the growth of the carburized layer as well as to block the intrusion of C by the oxide film in order to improve the metal dusting resistance.
- the carburized layer can be any material that can be used as the carburized layer.
- Reaction proceeds from the right side to the left side, and the generated C is adsorbed on the surface of the metal material and is formed by invading the inside of the metal material.
- ⁇ is positive, it has the effect of increasing the activity of C, a solute element. If the activity of C in the metal material increases, the amount of solid solution C decreases, and the flux into the interior decreases. It seems that the growth will slow down the growth.
- 0 and 11 are usually used as additional elements in steel, and as a result of investigating the effect of their addition, they are effective in improving metal dusting resistance. Turned out to be.
- N can be used for improving the metal dusting resistance.
- elements that form stable carbides in metallic materials such as Ti, Nb, V, and Mo also have the effect of suppressing the growth of the carburized layer, so the effects of their contents were examined.
- the effect of elements that form stable carbides in the above metal materials to suppress the growth of the carburized layer is almost proportional to the atomic concentration, and the contents of Mo and W are 1/2 of the atomic concentration, and others. It was found that the above effect could be quantitatively shown by the index if the total concentration of the elements was taken as the index and the total concentration was taken as the index. This indicates that, as described above, these elements suppress the growth of the carburized layer by forming stable carbides by combining with carbon invading from the surface.
- the incorporation of an element that strengthens the oxide film formed on the surface suppresses the penetration of C into the metal material and the above-described interaction assistance coefficient ⁇ .
- the high Cr and high Ni—Fe alloys are resistant to high carbon content by containing the elements whose carbon content is positive and, in addition, by simultaneously containing an appropriate amount of carbide forming elements to suppress the growth of the carburized layer in a carburizing atmosphere. It was found that metal dusting can be greatly improved.
- rare earth elements such as La, Ce, Nd and Y improves corrosion resistance and oxidation resistance at high temperatures. This is considered to be due to the fact that the above-mentioned elements promote uniform formation of oxide films of Cr, A1 and Si, and also enhance the adhesion between the oxide film and the interface of the metal material.
- the metal dusting resistance is increased by the two functions of enhancing the protection of the oxide film formed on the surface and suppressing the growth of the carburized layer due to the positive interaction assistance coefficient ⁇ .
- Si and A1 When a large amount of Si and A1 is included, the hot workability and weldability are significantly reduced.
- P, S and N described above are elements that increase the interaction assistance coefficient ⁇ , and improve the metal dusting resistance.
- the resistance to metal dusting can be greatly increased by including a large amount of Si and A 1 rather than including P, S and N. Therefore, when high metal dusting resistance is required, a large amount of Si and A1 is contained, thereby reducing the hot workability and weldability, and limiting the contents of P, S and N. It is better to control by doing so.
- the present invention has been completed based on the above findings.
- Cr is a basic component of the metal material according to the present invention intended for use at high temperatures. Cr has the effect of combining with the metal that has penetrated into the metal material and delaying the growth of the carburized layer in a high-temperature use environment, thereby ensuring good metal dusting resistance. In order to obtain this effect, the content needs to be at least 10%. However, if the content exceeds 35%, the toughness is reduced and the hot workability is deteriorated, so that production becomes difficult. Therefore, the content of Cr was set to 10 to 35%. When the Cr content is 15% or more, the metal dusting resistance is further improved. A more preferable content of Cr is 18 to 33%, and a content of 25.2 to 33% is most preferable.
- Ni is a basic component of the metal material according to the present invention, and has an effect of maintaining high-temperature strength and structural stability, and enhancing corrosion resistance by coexisting with Cr. Ni also has the effect of suppressing the occurrence of metal dusting. This These effects are exhibited when the Ni content is 30% or more, and the effect becomes remarkable as the Ni content increases up to 78%. Therefore, the content of Ni was set to 30 to 78%.
- the Ni content is more preferably 48 to 78%, and even more preferably 50 to 78%. It is extremely preferable that the content of Ni is 56 to 78%.
- C may not be added. If added, it has the effect of increasing the strength of the metal material. To ensure this effect, the content of C is preferably set to 0.01% or more. However, if its content exceeds 0.2%, the hot workability and weldability of the metal material will be reduced. Therefore, the content of C is set to 0.2% or less. When C is added, its content is preferably in the range of 0.01 to 0.18%, and more preferably in the range of 0.02 to 0.15%.
- Si has a deoxidizing effect when melting a metal material.
- Si forms a Si oxide film under the Cr oxide film on the surface of the metal material to suppress the intrusion of C into the metal and increase the activity of C in the metal material, thereby preventing metal dusting.
- the content of 31 needs to be 0.01% or more.
- the addition of a large amount of Si lowers hot workability and weldability. In particular, if its content exceeds 4%, the hot workability and weldability are significantly reduced. Therefore, the lower limit of the Si content was set to 0.01% and the upper limit was set to 4%.
- the lower and upper limits of the Si content are more preferably 0.05% and 3.5%, respectively, more preferably 0.1% and 3.2%.
- the contents of P and S as impurities can be up to 0.04% and up to 0.015%, respectively.
- the Si content is considered from the viewpoint of weldability and hot workability.
- the upper limit of the content is preferably 2%, and the upper limit of the A1 content is also preferably 2%. Good when the upper limit of the N content described below is set to 0.055% and the upper limits of the P and S contents are set to 0.03% and 0.01%, respectively. Since high hot workability and weldability can be ensured, in this case, the Si content may be set to 1.1% or more in order to greatly increase the metal dusting resistance.
