wcb casting

WCB Heat treatment process: generally all castings need to be anneal or normalization. Anneal at 890-910° Normalization at 870-890 °C WCB is also indicated In China standard of GB/T 12229 General Purpose Industrial Valve Specification of Carbon Steel Casting. The chemistry and mechanical property are same as A216 WCB. It is same as Chinese casting material of Manufacture Process: Sand Casting or Precision Investment Casting. Valve bodies/bonnet.

Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite. It is the most common cast iron and the most widely used cast material based on weight. It is used for housings where the stiffness of the component is more important than its tensile strength, such as internal combustion engine cylinder blocks, pump housings, valve bodies, electrical boxes, and decorative castings. Grey cast iron's high thermal conductivity and specific heat capacity are often exploited to make cast iron cookware and disc brake rotors.
