Description
The invention relates to metallurgy, intended for nickel-based alloys used in aggressive oxidizing environments.
The known corrosion-resistant alloy Nicrofer 6616hMo alloy C-4 (No. 2.4610), the weight percentage: 14.5-17.5 Cr, 14.0-17.0M o, less than or equal to 3.0Fe, less than or equal to 0.009C, less than or equal to 1.0Mn, less than or equal to 0.05Si, less than or equal to 2.0Co, less than or equal to 0.7Ti, less than or equal to 0.020P, less than or equal to 0.010S, nickel and other inevitable impurities (handbook "corrosion-resistant, heat-resistant and high-strength steel and alloy", M., Prometey alloy, 2008, pages 304-306).
The alloy is useful for making devices that operate in a variety of chemical environments, both at room temperature and at elevated temperatures. In particular for flue gas desulfurization; an etching bath and an acid recovery device; an apparatus for producing acetic acid and agrochemicals.
The closest analogue of the present invention is KHN65MVU (EP760) alloy, in weight percent: not more than 0.02C, not more than 0.1Si, not more than 1.0Mn, 14.5-16.5 Cr, 15.0-17, 0Mo, 3.0-4.5W, not more than 0.5Fe, not more than 0.012S, not more than 0.015P, nickel and inevitable impurities, the rest (GOST 5632-.
For creating structures (columns, heat exchangers, reactors), chemical, petrochemical industries (production of acetic acid, epoxy, vinyl acetate, melamine, complex organic compounds) and other temperature ranges from-70 to 5000 degrees celsius.
KhN65MVU alloy and its welding joint can be on KCl-AlCl3–ZrCl4The temperature can reach 500 deg.C when used in environment, and the temperature is higher than the specified valueAt the temperature, besides intergranular corrosion and corrosion cracking, the elongation of the alloy is sharply reduced from 48% to 7.3-13% at 550 ℃, the elongation is up to 2.5% at 625 ℃, and embrittlement of metal is shown after deformation.
The problem to which the invention relates is in the chloride plant (KCl-AlCl)3–ZrCl4) In a working environment at temperatures up to 650 c, alloys with high corrosion performance are produced.
The technical result of the invention is an alloy with high plasticity when working in the temperature range of 550 ℃ to 625 ℃ and increased molten chlorides KCl, AlCl at temperatures up to 650 DEG C3+(ZrCl4 HfCl4) Corrosion cracking resistance of (1).
The specific technical result is an alloy containing carbon, silicon, manganese, chromium, molybdenum, phosphorus, sulfur, iron, nickel and unavoidable impurities, which according to the invention additionally contains the following proportions, in weight percent, of the components titanium, aluminum, niobium, magnesium:
in order to obtain stable structural and plastic properties, the contents of chromium, molybdenum and iron are preferably related to the following ratios:(the ratio of the total mass percent of chromium and molybdenum to the mass percent of iron is not less than 46.4)
In order to obtain a stable structure and high corrosion performance, the contents of niobium and carbon are preferably related by the following ratio:(the ratio of the mass percent of niobium to the mass percent of carbon is not less than 1.66.
The contents of chromium, molybdenum, iron, niobium and carbon are preferably related to the following ratios:
by comparative analysis with prototypes, we can conclude that the claimed alloy differs from the known alloys in that: the alloy is characterized by comprising the following components, by weight, low carbon content (changed from less than or equal to 0.02% to less than or equal to 0.006%), molybdenum (changed from 15.0-17.0% to 12.0-14.0%), chromium content (changed from 14.5-16.5% to 23.0-24.0%), iron (changed from less than or equal to 0.5% to less than or equal to 0.75%), and elements such as 0.01-0.03% of niobium, 0.01-0.06% of titanium, 0.1-0.2% of aluminum and 0.005-0.01% of magnesium.
Furthermore, in the specific case of the invention, the required element ratios are satisfied:
or
The limitations of the content of alloying elements in the alloys of the present invention were determined by studying the properties of the alloys for the selection of different compositions.
Carbon contents exceeding 0.006% lead to a reduction in the corrosion resistance in zirconium and hafnium salt solutions due to an increase in the carbide formation process (appearance of poor carbide phases) at high temperatures.
The content of chromium is 22.8-24% to ensure the heat resistance required by hafnium and zirconium oxide. When the amount of chromium incorporated is less than 22.8%, the alloy does not have the desired heat resistance, and exceeding 24.0% lowers the heat resistance of the alloy.
The introduction of molybdenum into the nickel alloy can raise the recrystallization temperature of the solid solution, suppress its softening, improve the heat resistance, and improve the plasticity in both short-term and long-term tests.
We select a molybdenum content of 12.0-14.0% to provide the mechanical properties required for short and long term loading and high temperatures. The addition of molybdenum is less than 12.0 percent, and the requirement of mechanical property cannot be met. When the content is more than 14.0%, the plasticity of the alloy is reduced, and thus, the workability of the alloy is deteriorated during metallurgical processing.
The niobium is added in an amount of 0.01 to 0.03% to bond residual carbon and nitrogen to carbides, nitrides and carbonitrides, thereby preventing the formation of chromium carbides and carbonitrides along grain boundaries. Niobium, added in an amount of 6 to 10 times the carbon content of the alloy, eliminates intergranular corrosion of the alloy and protects the weld from damage. When the content of niobium is less than 0.01%, the interaction with the residual carbon is ineffective, and the content of niobium more than 0.03% is disadvantageous in the formation of carbides.
When the silicon content exceeds 0.1%, the workability of the alloy is adversely affected and the alloy is embrittled due to the increase in the content of the silicate.
An increase in the manganese content beyond 1.0% leads to the appearance of eutectic melting, which leads to the destruction of the steel ingot during the press working, to a reduction in the heat resistance of the alloy, and also to a reduction in the local corrosion resistance.
Nickel is stable in hydrochloric acid even at the boiling point. However, the corrosion of nickel and nickel chromium of molybdenum alloys is exacerbated in the presence of chloride, fe (iii) ions and other oxidants, and the iron content is limited to no more than 0.75%.
The addition of 0.01-0.06% titanium improves the corrosion resistance of the zirconium and hafnium salt melts, allowing residual carbon to combine with carbides to form Ni in sufficient quantities3The Ti-type intermetallic compound has a positive influence on the heat resistance of the alloy at the working temperature of 500-700 ℃. When the titanium content is less than 0.01%, the corrosion resistance requirement is not satisfied, and when the titanium content exceeds 0.06%, the workability of the alloy is lowered and a poor phase is formed due to the reactivity of titanium.
0.1-0.2% and 0.005-0.01% of aluminum and magnesium to remove residual oxygen, and, for aluminum, Ni is formed3An Al-type intermetallic compound, which has a positive influence on the heat resistance of the alloy. When the amount of these elements incorporated is less than the indicated amount, the necessary removal of residual oxygen cannot be achieved. If the content of these elements is exceeded, a large amount of non-metallic inclusions are formed.
When the sulfur content exceeds 0.012% and the phosphorus content exceeds 0.015%, coarse non-metallic inclusions are formed, adversely affecting the plasticity of the alloy.
In thatUnder the conditions, when the ratio is reduced below 46.4, the alloy structure becomes unstable (sigma phase is released), which adversely affects the plastic properties and corrosion resistance of the alloy.
In thatUnder the condition, when the ratio is less than 1.66, the corrosion resistance of the alloy is lowered.
The proportions of the elements in the proposed alloys are found experimentally and are optimal as they allow you to obtain the claimed combined technical result. The alloy performance is deteriorated and unstable without violating the element proportion, and the composite effect is not achieved.
Examples of the invention.
And smelting the alloy ingot in a vacuum induction furnace. According to GOST 14019-. In chloride melt KCl, AlCl3+(ZrCl4 HfCl4) In the process of carrying out the industrial test of corrosion cracking resistance of the alloy
Table 1 shows the chemical composition of the alloy ingots with various composition selections as well as the prototype alloys. Table 2 shows the results of the determination of the plastic properties of the alloys shown in Table 1 according to GOST 14019-2003 bending at an angle of 90 degrees. Table 3 shows the alloy shown in table 1 in the presence of molten chloride KCl,AlCl3+(ZrCl4HfCl4) Industrial test results of resistance to corrosion cracking at T650 c for 100 hours.
From tables 1, 2 it can be seen that the alloys satisfying the required composition (alloys 1, 2), having plasticity properties at 550 ℃ and 625 ℃ higher than those of the prototype alloy, and alloy 3 not satisfying the required composition, having plasticity properties lower than those of alloys 1, 2, resulted in cracking according to the GOST 14019-.
As can be seen from table 3, the alloys (alloys 1, 2) satisfying the required composition have a lower corrosion rate than the prototype alloy, and no cracks were found by visual inspection. Alloy 3, which is an undesirable composition, has a corrosion rate that exceeds that of alloys 1 and 2 (but is lower than that of the prototype alloy) and visual inspection reveals cracks in the sample.
