BÖHLER L059
BÖHLER L059 (2.4605/N06059) is a nickel-chromium-molybdenum material with high mechanical strength and excellent corrosion resistance. Due to its particularly low carbon and silicon content, the material does not tend to form precipitates at grain boundaries during welding or hot forming.
BÖHLER L059 offers excellent corrosion resistance, both under oxidizing and reducing conditions, high resistance to chloride-induced pitting and crevice corrosion as well as insensitivity to stress corrosion cracking and resistance to mineral acids, especially sulphuric/hydrochloric acid mixtures.
The alloy is therefore suitable for a wide range of applications in the chemical, petrochemical, energy and environmental technology sectors in chloride-containing media, in particular plant components in the pharmaceutical industry and also agitators for flue gas desulphurization plants (FGD) in fossil-fired power plants and waste incineration plants, components for seawater and concentrated brines, equipment and components for geothermal and sour gas applications, reactors for acetic acid and acetic anhydride as well as hydrofluoric acid and sulphuric acid coolers.
