Definitions
- the invention relates to a steel alloy for a ferritic steel with excellent creep strength and oxidation resistance at elevated use temperatures according to claim 1.
- the invention relates to seamless or welded tubes made of this steel alloy, the z. B. are used as heat exchanger tubes in heaters or power plant boilers in temperature ranges from about 62O 0 C to about 750 0 C.
- High temperature, high creep, and corrosion resistant high temperature materials for use, for example, in power plants are generally based on either ferritic, ferritic / martensitic or austenitic iron-based alloys, or nickel-base alloys.
- the specific requirements in the lower temperature stages of the heat exchanger tubes consist in particular in a low thermal expansion.
- Austenitic grades can not be used since their thermal expansion is too high in the described temperature range. For the elevated temperatures in the boiler, the previously available ferritic / martensitic materials are no longer in question, since with sufficient corrosion resistance whose creep or heat resistance is no longer sufficient.
- a sufficient combination of properties of corrosion resistance and heat resistance offer nickel-based alloys with nickel contents of over 50 wt .-%.
- the steels are thus extremely expensive and the processing to seamless pipes is also quite problematic.
- austenitic steels are currently being used.
- disadvantage here are the high alloying costs (Ni up to 30%), poor processability and lack of thermal conductivity.
- Chromium-rich ferritic steel is significantly cheaper compared to austenitic stainless steel and has a higher coefficient of thermal conductivity and a lower thermal expansion coefficient.
- chromium-rich ferritic steel also has a high oxidation resistance, which is advantageous for a hot steam, z. B. in heaters or boilers, is.
- oxide films form as a coating (scale or scale layer), they can detach at corresponding boiler temperature and / or boiler pressure changes, settle in the steel pipes and clog them.
- ferritic iron-based alloys for pipes or pipelines, which offer the required creep and corrosion properties even at higher operating temperatures above 620 ° C. For example, creep rupture strengths of 105 hours at this temperature stress for a load of 100 MPa without breakage should be achieved.
- Steels which are available for use at temperatures of up to about 62O 0 C or 65O 0 C are ferritic / martensitic steels with Cr contents of, for example. B. 8 to 15%.
- Corresponding steels are disclosed, for example, in DE 19941 411 A1, DE 692 04 123 T2, US 2006/0060270 A1, DE 601 10 861 T2 and DE 69608 744 T2.
- the alloy concepts disclosed there generally have expensive alloy additives or are also unsuitable for use in temperature ranges above 620 ° C.
- Concepts based on incoherent MX or M 2 X precipitations to increase creep resistance (DE 199 41 411 A1, DE 601 10 861 T2, US 2006/0060270 A1) have several disadvantages.
- the abovementioned precipitation phases can not be produced in sufficient proportions by volume since an increase in the content of the metallic (eg Ti 1 Nb or V) as well as the non-metallic components (C or N) not only leads to an increase in the phase fraction, but also the solution temperature the phase increased. As a result, the formation temperature of the precipitates is above a reasonable heat treatment temperature and sometimes even above the solidus temperature of the alloy.
- the metallic eg Ti 1 Nb or V
- C or N the non-metallic components
- the formation temperature of the precipitates is directly related to their size, one obtains either a relatively small volume fraction of effective reinforcing particles ( ⁇ 1%) or a high volume fraction of coarse particles (> 1 ⁇ m), which remain ineffective with regard to creep resistance.
- the MX and M 2 X particles preferably precipitate in the interior of the grain. It is to be expected that at use temperatures> 630 ° C the influence of grain boundary creep increases in relation to dislocation creep.
- a depletion of reinforcement phases at grain boundaries is therefore to be regarded as particularly critical.
- the incoherent precipitates are more prone to coarsening than coherent because, on the one hand, the interfacial energy as a driving force for interface minimization is higher than for coherent particles and, on the other hand, easily diffusing elements such as C and N are part of these particles.
- the alloy described in WO 03/029505 is a further development of the known under the name Kanthai FeCrAI alloy, the z. B. for heating elements for temperatures above 1000 0 C is used.
- This alloy has a high chromium and aluminum content to ensure the most efficient conversion of electrical energy into heat.
- the combination of high chromium and aluminum contents means that these alloys are fully ferritic at chromium contents above 16% and aluminum contents above 4%, even at temperatures above 750 ° C., so that an austenite-ferrite transformation is possibly only possible to a limited extent.
- Such steels are not suitable for use in the power station sector, and chromium contents above 16% also impair the deformation capacity at typical processing temperatures when rolling seamless pipes (900 - 1200 ° C.). This reduced deformability can lead to the formation of cracks during rolling. As a result, such alloys are not suitable for the production of pipes and sheets.
- US Pat. No. 6,332,936 B1 describes exclusively powder-metallurgically produced intermetallic alloys for the production of sheet metals based on the Fe-Al system and contains the intermetallic phases Fe3AI, Fe2Al5, FeAl3, FeAl, FeAIC, Fe3AIC and combinations of these phases.
- the described FeAl-B2 phase is used exclusively as a matrix in these publications.
- the powder metallurgy production of such an intermetallic alloy is unsuitable for the large-scale production of pipes and sheets.
- the object of the invention is to provide a cost-effective steel alloy for a ferritic at use temperature steel, which satisfies the stated requirements regarding creep rupture strength and oxidation resistance, even at operating temperatures up to about 750 0 C.
- Another object is to produce from this steel alloy workpieces such. As hot-rolled seamless or welded tubes, sheets, castings or tool steels to provide.
- the inventive alloy concept differs fundamentally from the known alloy concepts.
- the at operating temperature fully ferritic to about 75O 0 C alloy obtained their excellent creep and corrosion properties according to the new innovative approach by coherent finely divided precipitates of nanoparticles of a stabilized by chromium (Ni, Co) AI-B2 intermetallic order phase.
- the precipitates are coherent to the ferritic matrix and uniformly and finely distributed throughout the grain both within the grain and near grain boundaries. Advantages of this steel alloy are significantly lower cost and also the coherent precipitates of the intermetallic (Ni, Co) AI-B2-phase effect compared to known alloy concepts significant increase in creep resistance at temperatures above 620 0 C and even above 650 ° C to about 750 0 C.
- the concept underlying this invention dispenses with expensive or hard-to-obtain elements for producing an intermetallic amplification phase.
- the (Ni, Co) Al phase with B2 structure requires significantly lower Ni or Co contents than available austenitic steels.
- the peculiarity of the B2 phase in the Fe-Cr-Al (Ni 1 Co) system lies in the pronounced miscibility gap that can be controlled via the Cr content for (Ni 1 Co) Ai.
- B2 phase contents in steel above 8 mol% (VS2) are unfavorable because of the associated reduction in toughness and poorer machinability of the steel and should therefore be avoided.
- the elements Ni, Al and small amounts of Fe could be detected.
- Fe, Cr 1 Al and Si could be detected in the matrix.
- the mean particle radius of the B2-NiAl phase is about 40 nm, the molar phase fraction about 5.6%.
- the coarsening in the period of conventional qualifications is well below the maximum effective mean particle radius value of about 500 nm.
- the B2 phase can be sufficiently stabilized at application temperatures above 620 0 C to about 750 ° C
- the steel according to the invention Cr is alloyed in contents of 2 to ⁇ 16 wt .-%.
- an advantageous embodiment of the invention is obtained by setting an excess of AI in relation to Ni or Co (superstoichiometric for the adjustment of NiAl or CoAI) also a further significant increase in the oxidation resistance.
- the composition should be chosen so that at the application temperature, a stable structure of ferritic structure and the (Ni, Co) AI-B2 phase is given as main components.
- the following composition in% by weight must be observed:
- the elements Si and Mn can be present either only in the context of steel-like accompanying elements or alloyed for additional solid solution hardening in amounts of up to 1% in each case. As favorable contents of max. 0.4% for Si and 0.5% for Mn. Si serves to slightly increase the heat resistance. If this is in the foreground of the application, higher levels are recommended. Mn has a negative effect on the steam oxidation behavior at higher levels. If this risk does not exist in the application, Mn can be added as an additional element to increase the strength at room temperature and elevated temperatures.
- the C content is of minor importance for the present alloy concept, but should not exceed a value of 1.0%. As favorable, maximum contents of 0.5% have been found. Contents above 1% complicate the processability and favor the formation of coarse and thus harmful special carbides. At C contents below 0.5%, the formation of special carbides is already greatly reduced. Depending on the operating temperature, however, the C content must be adjusted in order to avoid a strong precipitation and growth of these special carbides when used.
- Toughness of the steel set a homogeneous and fine grain structure, which over a
- Microalloying one or more elements of V, Ti 1 Ta, Zr or Nb is achieved, wherein the carbon present in the steel is bound in the form of fine MX carbides.
- the following maximum contents have been found to be favorable: max. 0.3% V, max. 0.1% Ti 1 max. 1.0% Ta, max. 0.05% Zr 1 max. 0.2% Nb, where a maximum total content of 0.5% has proven favorable.
- Mo and W which are alloyed with maximum contents of 1% (Mo) and 2% (W), respectively can be.
- the N content should be set as low as possible and is limited to max. Limit 0,0200%.
- surfactants to both internal interfaces, such as grain boundaries and phase boundaries, as well as the protective oxide layer interfaces; to influence specifically.
- These include the elements Hf, B, Y, Se, Te, Sb, La and Zr, which are alloyed in the range of the sum content of ⁇ O 1 1%.
- the steel alloy advantageous z. B. can be used for heat exchanger tubes in the power plant area, the use is not limited thereto.
- this steel alloy is also suitable for the production of sheet metal, castings, centrifugal castings or Tools for mechanical processing (tool steels) can be used, with the field of application via pressure vessels; Boilers, turbines, nuclear power plants or the chemical apparatus construction, that extends to all areas with corresponding temperature requirements and corrosion stresses.
- the steel alloy according to the invention is particularly advantageous because of the excellent Zeitsta ⁇ dfestmaschine and oxidation properties above 620 0 C to about 750 0 C, the use is, for example, even at temperatures above 500 0 C advantageous if it depends more on the strength of the material.
- FIG. 1 shows an image of the microstructure, generated by means of STEM, as well as the EDX-determined chemical composition of the matrix and the B2 phase of VS1.
- FIG. 2 shows the results of isothermal creep tests at 650 degrees Celsius and constant voltage on samples of the laboratory melt VS3.
