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
