WebHydrofluoric acid (HF) is a liquid or gas which is the most corrosive acid known when in concentrated form. Concentrated HF (70%) will fume on contact with air. 2. Symptoms of HF exposure. Even small amounts of HF can be fatal. Unlike other acids, dilute HF can react with tissue and bone without significant initial pain. WebJun 16, 2024 · Monel 400 and 500 are still the most popular materials used in HF acid service. Instead of traditional B7 or B16 bolting, HF acid valves require B7M bolting, which is heat treated. The treatment makes the bolting softer, which makes it more resistant to cracking when exposed to HF acid. While Monel spiral-wound gaskets are still the most …
