550-degree switch ball valve, pressure of 10 kPa; all other conditions are normal, with no erosion or cavitation. Can CF8M be used for the valve body? The valve internals can’t use CF8M, right? What material should be used instead?

CF8M is equivalent to ZG0Cr18Ni12Mo2Ti (GB 2100), which corresponds to 316 stainless steel; it is therefore no problem to use CF8M for the valve body. Given an operating temperature of 550°C, it is recommended to use CF8C for the valve body

Sometimes Chinese characters, sometimes foreign letters – people with two rotors, people with two dogs
