Definitions

  • the invention relates to the use of a titanium-free nickel-chromium-iron-molybdenum alloy with high resistance to pitting and crevice corrosion and high yield point and strength.
  • Alloy 825 is a material with high corrosion resistance used in the oil and gas and chemical industries.
  • the Alloy 825 alloy is sold under the material number 2.4858 and has the following chemical composition: C ⁇ 0.05%, S ⁇ 0.03%, Cr 19.5 - 23.5%, Ni 38 - 46%, Mn ⁇ 1 .0%, Si ⁇ 0.5%, Mo 2.5 - 3.5%, Ti 0.6 - 1.2%, Cu 1.5 - 3.0%, Al ⁇ 0.2%, Fe rest .
  • the PREN summarizes the alloying elements with a positive effect on pitting and crevice corrosion resistance in a material-specific index.
  • Alloy 825 (ISO 18274: Ni8065) has not yet established itself as a welding additive or filler metal (FM) and is rarely used. The reason for this is the difficult workability, which is reflected in the fact that the weld metal often shows hot cracks in the form of solidification and remelting cracks. These are particularly important in the critical applications of the oil and gas industry Processing problems that are inherent to the material represent an exclusion criterion, which means that an alternative welding filler material is often used instead of FM 825, namely the welding filler material FM 625 (ISO 18274: Ni6625). However, the FM 625 has the following disadvantages compared to the FM 825:
  • the weld metal made of FM 625 is less easy to rework mechanically, for example when overturning build-up welds or when leveling excessive weld seams, since it is significantly harder.
  • the hardness of FM 825 weld metal is no more than 250 HV10, while the hardness of FM 625 weld metal is usually 310 HV10.
  • the alloying element niobium poses the risk of undesired gamma" or delta phase formation, particularly during heat treatment after welding (so-called Post Weld Heat Treatment, PWHT) or during hot forming, for example through inductive bending of build-up welded pipes
  • PWHT Post Weld Heat Treatment
  • the formation of gamma" or delta phase is accompanied by a drastic loss of corrosion resistance and/or ductility.
  • the FM 825 has another disadvantage, namely titanium as an alloying element. Titanium can easily oxidize in an uncontrolled manner during fusion welding if the material is in the liquid phase a depletion of the interstitial titanium in the weld metal - and can thus lead to an undefined reduction in its stabilizing effect. In addition, the oxidation or nitration of titanium during welding can lead to a significant reduction in the quality of a welded joint, in that the titanium oxide or titanium nitride particles produced and distributed in the weld metal reduce the strength, ductility and/or corrosion resistance of the weld metal.
  • the alloy is openly melted in continuous or ingot casting, b) to eliminate the segregations caused by the increased molybdenum content, homogenization annealing of the slabs/billets produced at 1150 - 1300°C 15 h to 25 h is carried out, wherein c) the homogenization annealing is carried out in particular after a first hot forming.
  • Alloy 825 CTP has a higher PREN of approx. 42 than Alloy 825 and is not titanium alloyed. Alloy 825 CTP material was developed to overcome the following disadvantages of Alloy 825:
  • the aim of the invention is to bring the material described in DE 102014002401 A1 to a new area of application.
  • Fe residue as well as impurities resulting from the melting process, which is processed as an alloyed solid in the form of wire, strip, rod or powder via the molten phase and is used in wet corrosion applications in the oil and gas and chemical industries.
  • Alloy 825 CTP as a filler material for welding is not described in DE 102014 002 402 A1 and the product forms of welding wire, welding strip and powder (e.g. for additive manufacturing) are not mentioned.
  • the new area of application is characterized by the fact that the material is basically processed via the molten phase.
  • the element carbon is given in the alloy as follows:
  • carbon can be limited as follows:
  • the chromium content is between 20.0 and 23.0%.
  • Cr can preferably be set in the alloy within the spread range as follows:
  • the nickel content is between 39.0 and 44.0%, with preferred ranges being set as follows:
  • the molybdenum content is between > 4.0 - ⁇ 7.0%, whereby, depending on the area of application of the alloy, preferred molybdenum contents can be set as follows:
  • Figure 2 shows a macro cross-section of the welded joint. No hot cracks were found in the weld.
  • the Alloy 825 or FM 825 CTP has been melted in the following compositions:
  • the material FM 825 CTP has been melted on an industrial scale as a welding filler material and further processed into welding filler material, among other things as welding wire with a diameter of 1.00 mm.
  • Welding speed 55 cm/min and pure argon was used as the protective gas.
  • the build-up welding was partially carried out in 2 layers. Both the visual inspection and the dye penetrant inspection showed that neither macro nor micro hot cracks could be detected on the weld metal surface.
