Ductile Cast Iron Valve
Ductile cast iron can also be called spheroidal graphite cast iron. Its characteristic is that its base structure appears in a spherical form during the production and casting process. The spherical structure of ductile cast iron has the function of absorbing pressure, so it can withstand heavy impacts and allow plastic deformation. In addition, ductile cast iron has high carbon and high silicon chemical composition, which makes ductile cast iron also has corrosion resistance and the same strength as steel, and is widely used in fire protection and other fields.
