WebLewis® acid valves are designed to provide maximum corrosion resistance, outstanding performance and reliability in 93-99.5% sulphuric acid and oleum applications. WebNov 30, 2024 · It is not suitable for use as a material for pump valves; ordinary stainless steels such as 304 (0Cr18Ni9) and 316 (0Cr18Ni12Mo2Ti) have limited use for sulfuric acid media. Therefore, pump valves for sulphuric acid are usually made of high-silicon cast iron (difficult to cast and process) and high-alloy stainless steel (alloy 20). WebSulfuric acid Type 304 can be used at room temperature for concentrations over 80%. Type 316 can be used in contact with sulfuric acid up to 10% at termpera- tures up to 120ºF (50ºC) if the solutions are aerated; the attack is greater in airfree solutions. Type 317 may be used at temperatures as high as 150ºF (65ºC) with up to 5% concentration. jr円町駅 バス
