Incoloy 690
INCONEL alloy 690 is a high-chromium nickel alloy which is particularlysuitable for use in oxidising media. Good mechanical properties at room temperature and high temperature, paired with high ductility. Typical applications are: treatment of radioactive waste,components in boilers and steam generators in pressurised water reactors,production of alkali metal sulphates using Mannheim furnaces, fittings in combustion units for crude oil (oil ash corrosion)and glass and silicate production.
