Why Hastelloy C276 for Ball Valves?

Hastelloy C276 ball valves combine the ball valve's proven shutoff design with near-universal resistance to hot hydrochloric, sulphuric and phosphoric acids, wet chlorine, and mixed oxidising-reducing media. This makes them the standard specification for hydrochloric acid, sulphuric acid dilution, wet chlorine gas, sour gas with high H2S, and aggressive waste streams.
