When engineers ask about Inconel 718 corrosion resistance in sulfuric acid, my first reaction is usually the same: do not answer too quickly. Alloy 718 is a very capable nickel-chromium alloy, but sulfuric acid is one of those environments where a casual \u201cnickel alloy = safe\u201d mindset gets people into trouble.
