  • the alloy is used to manufacture equipment operated in a wide range of chemical environments, at room and elevated temperatures. In particular - for adsorbers during flue gas desulfurization; pickling baths and acid regeneration plants; Acetic acid and agrochemical plants.

  • the KhN65MVU brand alloy and its welded joints can be used in KCl-AlCb-ZrCU environments only up to 500 ° C, since at temperatures above the specified value, in addition to intergranular corrosion and corrosion cracking, the alloy sharply decreases the relative elongation from 48% to 7.3-13% at 550 ° C and to 2.5% at 625 ° C and metal embrittlement when deformation is applied.
  • the technical result of the invention consists in obtaining an alloy with an increased level of plastic properties during operation in the temperature range from 550 ° C to steadiness and, accordingly, the deterioration of the processability of the alloy during metallurgical processing.
  • Niobium in an amount of 0.01–0.03% binds residual carbon and nitrogen into carbides, nitrides, and carbonitrides, prevents the formation of chromium carbides and carbonitrides at grain boundaries.
  • the addition of niobium in an amount 6–10 times higher than the carbon content in the alloy eliminates intergranular corrosion of the alloys and protects the welds from damage.
  • the niobium content is less than 0.01%, its interaction with residual carbon is ineffective, and the niobium content above 0.03% is not rational for carbide formation.
  • An increase in the manganese content of more than 1.0% leads to the appearance of a low-melting eutectic, which leads to the destruction of the ingot during pressure treatment and reduces the heat resistance of the alloy, and also leads to a decrease in resistance to local corrosion.
  • Nickel is stable in HC1 even at boiling point. However, in the presence of chlorides, Fe (III) ions and other oxidizing agents, corrosion of nickel and nickel chromium of molybdenum alloys is enhanced, and the associated iron content is not more than 0.75%.
  • titanium in an amount of 0.01–0.06% increases the corrosion resistance in molten zirconium and hafnium salts, binds residual carbon to carbides and leads to the formation of a sufficient amount of intermetallic Ni 3 Ti, which, at an operating temperature of 500–700 ° C positive effect on the heat resistance of the alloy.
  • the content of titanium is less than 0.01%, the requirements for corrosion resistance are not met, and an excess of titanium content above 0.06% leads to a decrease in the processability of the alloy and the formation of undesirable phases due to the reactivity of titanium.
  • Aluminum and magnesium in the amount of 0.1-0.2% and 0.005-0.01% are introduced into the alloy for the removal of residual oxygen, and also, as for aluminum, for the formation of intermetallic metal Ni 3 Al, which positively affects on the heat resistance of the alloy. With the introduction of these elements in quantities less than those indicated, the necessary removal of residual oxygen is not achieved. If the content of these elements is exceeded, coarse non-metallic inclusions are formed.
  • the corrosion rate of alloys (alloys 1, 2), satisfying the claimed composition, is lower than the corrosion rate of the prototype alloy, visual inspection did not reveal cracks, unlike the prototype alloy.
