VDM® Alloy 31 (1.4562/N08031)

VDM® Alloy 31 is an iron-nickel-chromium-molybdenum alloy with the addition of nitrogen. The alloy developed by VDM Metals closes the gap between high alloyed austenitic special stainless steels and nickel alloys.

Characteristics of VDM® Alloy 31

VDM® Alloy 31 (1.4562/N08031) is characterized by:

  • outstanding corrosion resistance in alkaline and acidic halide-containing media
  • excellent resistance to sulfuric acid, even in highly concentrated form
  • excellent resistance to corrosion and erosion in phosphoric acid media
  • outstanding resistance to surface corrosion and local corrosion in chlorine dioxide bleaching plants in paper production
  • excellent resistance in reducing and oxidizing media as well as in boiling azeotropic nitric acid

Applications of VDM® Alloy 31

Typical fields of application for VDM® Alloy 31 are:

  • components for flue gas desulfurization (FGD) plants
  • plants for the production of phosphoric acid via the wet digestion process
  • pipes and heat exchangers for sulfuric acids contaminated with chlorides
  • pipes containing ocean water and brackish water, condensers and chillers
  • pickling plants for sulfuric acid as well as nitric-hydrofluoric acid
  • treatment of sulfuric acids from waste
  • evaporation and crystallization of salts
  • components for the cellulose and paper industry
  • digestion of ores, e.g. in HIPAL (high-pressure acid leach) plants for the digestion of laterite ores
  • mineral oil production and refineries
  • organic acids and ester synthesis
  • fine chemicals
  • strain-hardened transport and feed pipes as well as slicklines, wirelines and flowlines in the transport of oil and gas
  • marine scrubber / ship diesel scrubber
  • longitudinal welded tubes for waste to energy
