What is the maximum temperature beyond which brass or bronze valves are not used?

Brass and bronze valves have good properties at low to moderate temperatures, but they lose strength and creep resistance as temperature rises. The zinc in brass can volatilize or compromise the alloy, and the material softens under heat, making it harder to seal and withstand pressure reliably. Because of these limitations, these valves are not used in hot service beyond about five hundred fifty degrees Fahrenheit. In systems hotter than this, valves built from higher-temperature materials, like steel, are preferred.
