VDM® Alloy 926 (1.4529/N08926)

VDM® Alloy 926 is an austenitic, special stainless steel. Due to its high molybdenum concentration, this alloy   has a generally much improved corrosion resistance and resistance against pitting corrosion and crevice corrosion. This also has a positive effect on the resistance against stress corrosion that is induced by pitting corrosion.

Characteristics of VDM® Alloy 926

VDM® Alloy 926 is characterized by:

  • very good resistance against chloride-induced stress corrosion,
  • increased resistance against stress corrosion in comparison to other austenitic stainless steels,
  • excellent general corrosion resistance when in contact with oxidizing and reducing media,

Applications of VDM® Alloy 926

Typical applications for VDM® Alloy 926 are:

  • Vaporizers, heat exchangers, tank housings, etc. in phosphorus acid production  
  • Facilities and pipework in the use of diluted sulfuric and phosphorus acid, even if these are contaminated with chlorides 
  • Distributor systems and coolers for sulfuric acid plants 
  • Concentration and crystallization plants in salt extraction by vaporization 
  • Fire extinguishing systems, sea water filtration, hydraulics and injection systems of off-shore engineering 
  • Pump frames of oil extraction pumps 
  • Pump lines and couplings, wire lines in oil and gas extraction 
  • Condenser pipes and pipework systems in power plants with heavily contaminated cooling water 
  • Parts for flue gas desulfurization that are exposed to modest corrosion strain 
  • Facilities and parts for the bleaching phase of the pulp industry 
  • Flexible pipes in the off-shore industry 
  • Tanks for storing and transport of aggressive chemical substances
