The chemically stable and high-temperature resistant nickel and cobalt
alloy 2.4605 (alloy 59) is mainly used in the chemical industry, flue
gas desulphurisation plants, paper industry.

Alloy 59 is a nickel-chromium-molybdenum alloy with excellent corrosion

resistance and high mechanical strength. The alloy has excellent
resistance to both oxidizing and reducing media, and possesses superior
resistance to chloride pitting and stress corrosion cracking.

The alloy is widely used in the most severe environments. Some
applications include: flue gas scrubber components, bleach plant and
digester components for the pulp and paper industry, sour gas handling
equipment, sulfuric acid coolers, waste incinerators and seawater
