Definitions

  • the alloy can also contain from 3 to 4.5%
  • nickel-chromium-molybdenum alloys cannot be used in many instances.
  • Another object of the invention is -to provide alloys ⁇ which when used for the manufacture of apparatus need not be subjected to a heat treatment after welding.
  • the present invention comprises the discovery that a greatly improved nickel-chromium-molybdenum alloy can be produced if the silicon content of the alloy is maintained at an extremely low level. In all Vother phases with a similar composition are also formed.
  • Vbut silicon-free alloy nickel 58.8%, chromium 15.5%
  • the silicon level should be less than 0.2%
  • nickel-chromiummolybdenum alloys preferably should be from 0 to 0.1%, and more preferably from 0 to 0.012%.
  • the above described nickel-chromiummolybdenum alloys have a silicon content of 0.5 to 1%. It has been suggested in the past that the presence of silicon is needed for deoxidation of the alloy and to improve the forgeability of the alloys. Silicon is also almost always incorporated in the alloy as an impurity due to the fact that silicon-containing materials are used as deoxidation agents.
  • a highly corrosion and heat resistant nickel-chromium-molybdenum alloy is obtained with improved resistance to intergranular corrosion by using: a nickel content of 40 to 65%, preferably of 55 to 60%, part of the nickel, up to a maximum of 20%, if desired being replaced by cobalt; a chrome content of 14 to 26%, preferably 22 to 25%; a molybdenum content of 3 to 18%, preferably 14 to 17%; an iron content of O to 30%, preferably 0 to 7%; a tungsten content of 0 to 5%; a carbon content of not more than 0.1%; a manganese content of up to 3%; a silicon content of from 0 to less than 0.2%; as well as a phosphorus and sulfur content totaling not more than 0.1%, if these are produced from corresponding metals or master alloys which are free of silicon and by subsequent deoxidation with a silicon-free alkaline-earth metal, preferably magnesium, or a silicon-free alkaline-earth metal
  • an alkaline-earth metal for instance magnesium, or a siliconfree alkaline-earth metal master alloy, is used as deoxidation agent, whereby the disadvantageous properties of the silicon in the alloy are avoided.
  • Alloys deoxidized with magnesium, as an example, show much more sluggish precipitates. Moreover, these cover the grain boundaries only very slowly.
  • the alloys with the following composition proved to be especially favorable: 55 to 60% nickel, 22 to 25% chromium, 14 to 17% molybdenum, iron 2%, manganese l%, silicon 0 to 0.19% and carbon 0.08%.
  • the range of dangerous precipitates is in addition reduced by the increase of the chromium content as compared with alloys of normal composition Without silicon. They offer, therefore, increased safety to intergranular corrosion, especially after welding.
  • the graph set out in FIG. 4 shows the dependency of the thickness of alloy sheeting on its Si-content, i.e., what thickness such sheeting must have to insure that no intercrystalline corrosion occurs when such sheeting is not heated after welding.
  • the impairment is negligible with an Si-content of up to 0.1%, but becomes severe even with as low an Si-content as 0.2%.
  • the graph indicates the maximum thickness up to which alloy sheeting can be welded without the Welding seam having to be heat-treated.
  • the area between the curve and the ordinate pertains to sheeting which will be adequately resistant to intercrystalline corrosion without heat treatment.
  • the values for Si-content and thickness fall outside this area, this means that the sheeting must be subjected to a heat treatment after welding.
  • the specimens used for the impact tests described in Table 2 were pieces 4 by 3 by 27 mm.
  • a nickel-chromiurrr-molybdenum alloy having high corrosion and heat resistance properties said alloy consisting essentially of from 40 to 65 nickel; up to 20% cobalt, the total amount of nickel and cobalt being from 40 to 65%; from 14 to 26% chromium; from 3 to 18% molybdenum; up to 30% iron; up to 5% tungsten; up to 0.1% carbon; up to 3% manganese; and a combined phosphorus and sulfur content of up to 0.1%, said alloy containing less than 0.2% silicon.
