Features: Alloy 926 has excellent resistance to pitting and crevice corrosion in media containing halides and hydrogen sulfide. It also has outstanding resistance to chloride-induced stress corrosion cracking, and resists to both oxidizing and reducing environments.
Applications: Sour (containing hydrogen sulfide) crude oil and natural gas well components, flue gas desulfurization system components, marine engineering piping, and corrosive chemicals containers.
