Application of Killed Carbon Steel in the Valve Industry

What is killed carbon steel?

Killed carbon steel, also known as deoxidized steel, is a type of steel that has been treated with a deoxidizing agent, such as silicon or aluminum, to remove oxygen and other impurities from the molten steel. This process helps improve the steel’s properties and makes it suitable for various applications in the valve industry.

Application in valve industry

One of the main advantages of using killed carbon steel in valves is its excellent weldability. The deoxidization process helps reduce the formation of porosity and other defects during welding, resulting in strong and reliable weld joints. This is particularly important in valve manufacturing, as valves often require welding to join different components together.

Killed carbon steel also offers good mechanical properties, including high strength and toughness. These properties make it suitable for withstanding the pressures and temperatures typically encountered in valve applications. Additionally, killed carbon steel has good corrosion resistance, which is crucial for valves that come into contact with corrosive fluids or environments.

In the valve industry, killed carbon steel is commonly used for manufacturing valve body, bonnet, stem, and other critical components. Its weldability, mechanical properties, and corrosion resistance make it a good choice for valves used in various industries, such as oil and gas, petrochemical, power generation, and water treatment.
