Ductile iron is processed by a ball and bred to obtain a spherical graphite cast iron effectively improve the mechanical properties, in particular to improve the ductility and toughness, but also to obtain high strength than carbon steel. Ductile iron was developed in the 1950s as a high-strength cast iron materials, its overall performance is close to steel, is based on its excellent performance, has been successfully used for casting some of the complicated forces, strength, toughness, wear demanding higher parts. I produced ductile products, casting and diverse, strict production process, quality assurance. Welcome to contact us to discuss business.
