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:

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
