VDM® Alloy 926 (1.4529/N08926)

VDM® Alloy 926 is a superaustenitic stainless steel developed by VDM Metals. By increasing the molybdenum and nitrogen contents of VDM® Alloy 904 L, a material with markedly improved properties was obtained.

Characteristics of VDM® Alloy 926

In particular, VDM® Alloy 926 shows significantly higher resistance to localized corrosion in halide media, with superior mechanical properties.

VDM® Alloy 926 (1.4529/N08926) is characterized by:

  • very high resistance to pitting and crevice corrosion in halidemedia and in H2S containing sour environments
  • virtual immunity under practical conditions to chloride-ion stress-corrosion cracking
  • excellent general corrosion resistance in a wide range of media, both oxidizing and reducing
  • improved mechanical properties over VDM® Alloy 904 L
  • improved metallurgical stability over similar grades with only 18 % nickel
  • approved for pressure vessels by VdTÜV from -196 to 400 °C (-320 to 750 °F), and by ASME
refinery

Applications of VDM® Alloy 926

VDM® Alloy 926 is a polyvalent material which finds application in a wide range of industries:

  • fire fighting systems, seawater filtration systems and process, hydraulic and reinjection piping systems in the offshore industry
  • bleaching plants in cellulose pulp production
  • polished rods for corrosive oil wells
  • flexible pipe systems for the offshore industry
  • tubing and couplings, wire lines and flowline systems in sour gas production. In sour gas environment the alloy is listed in NACE Standard MR0175 (Sulfide Stress Cracking Resistant Metallic Materials for Oilfield Equipment) as acceptable up to Level V in the annealed or cold-worked condition at a hardness level of 35 HRC max.
  • components for flue-gas desulphurization plants, such as dampers and stacks
  • evaporators, heat exchangers, filters and mixers used in the manufacture of phosphoric acid
  • sulphuric acid distribution systems and coolers
  • concentration and crystallization of salts by evaporation
  • condensers and piping systems in power stations using polluted cooling waters
  • containers for transportation of aggressive chemicals
  • production of organic derivatives with acid Chloride catalysts
  • reverse-osmosis desalination plant
