Alloy Steel Valve Casting

Alloy Steel Valve Casting for industrial valve applications — WC6, WC9, C5, C12, C12A, CA15.

Alloy Steel Valve Casting

Alloy steel valve castings are designed for high-temperature and high-pressure service in power plants, refineries, and petrochemical facilities. Our alloy steel castings maintain their mechanical properties at elevated temperatures up to 600°C.

High-temperature gate valve bodies
Steam service globe valves
Power plant check valves
Pressure-retaining bonnet castings
Refinery valve components
Petrochemical control valve bodies

Available Grades

We stock tooling and have extensive production experience with the following grades: WC6, WC9, C5, C12, C12A, CA15. Custom alloy compositions are available upon request with MOQ.

Grade	Standard	Max Temp (°C)	Application
