Alloy 59 Sheet, plate, strip, rod, bar,  pipe/tube, forging, wire

• Introduction:
  • Alloy 59 is a nickel-chromium-molybdenum alloy with an  extra-low carbon and silicon content. The alloy was developed by ThyssenKrupp  VDM and has excellent corrosion resistance and high mechanical strength.
• Characters  of Alloy 59
  • l    Outstanding resistance to a wide range of corrosive  media under oxidising and reducing conditions
  • l    Excellent resistance to pitting and crevice corrosion  and freedom from chloride-induced stress-corrosion cracking [1]  
  • l    Excellent resistance to mineral acids, such as nitric,  phosphoric, sulphuric and hydrochloric acids and in particular to sulphuric  and hydrochloric acid mixtures
  • l    excellent resistance to contaminated mineral acids
  • l    Good corrosion resistance to hydrochloric acid over the  whole concentration range up to 40 °C (104 °F).
  • l    Good workability and weldability without susceptibility  to post-weld cracking
  • l    Approval for pressure-vessel use with wall temperatures  of –196 to 450 °C (– 320 to 840 °F)
  • l    Approved in NACE Standard MR0175, to the highest Level VII  for sour gas service
• Application of Alloy 59:
  • l    Components in organic processes involving chlorides, particularly  when acid chloride catalysts are employed
  • l    Digesters and bleaching plants in the pulp and paper industry
  • l    Scrubbers, reheaters, dampers, wet fans and agitators  for incinerator gas and flue gas desulphurisation (FGD)
  • l    Equipment and components in sour gas service [1]
  • l    Reactors for acetic acid and acetic anhydride
  • l    Sulphuric acid coolers
