Valves are essential in controlling the flow of liquids and gases in various industries. The materials used in valve production depend on the specific requirements of the application.
Common materials for valves include carbon steel, stainless steel, cast iron, and bronze. Carbon steel valves are robust and suitable for high-pressure applications. Stainless steel valves are resistant to corrosion and are often used in chemical and food processing industries. Cast iron valves are good for low-pressure applications, while bronze valves are known for their resistance to seawater and brine.
The ASTM A216/A216M standard provides specifications for carbon steel castings for valves, flanges, fittings, and other pressure-containing parts.
Meanwhile, the ASTM A351/A351M standard covers austenitic steel castings for valves, flanges, fittings, and other pressure-containing parts.
These standards help manufacturers and users select the right materials based on pressure and temperature requirements, ensuring that valves are safe and reliable for use in the U.S. market.
