Valve Material Compatibility Atlas
Which valve material survives which fluid. 308 rated body- and trim-material relationships across 54 industrial process fluids — from sulphuric acid and seawater to chlorine, hydrogen and caustic — the engineering reference for corrosion-driven material selection.
How do I choose a valve material for a corrosive fluid?
Match the body and trim material to the fluid's corrosivity: carbon steel suits hydrocarbons and non-corrosive utilities; SS 316L handles mild chemicals and many organics but pits in chlorides and dilute acids; duplex 2205 and super duplex resist seawater and chlorides; Hastelloy C-276 and Monel 400 handle aggressive acids and chlorine; titanium suits oxidising chlorides (but fails in dry chlorine); and PTFE-lined valves handle the most aggressive acids where no alloy is economical. The matrix below rates each material per fluid; click any fluid for the full selection guide.
Ratings are indicative for valve service and depend on concentration, temperature, velocity and contaminants — hover any cell for the engineering note, or open the fluid for full conditions. Always confirm against a corrosion table or materials engineer.
