Grey cast iron and ductile iron Casting

- Jul 12, 2019-

Grey cast iron refers to cast iron with flake graphite. Its main components are iron, carbon, silicon, manganese, sulfur and phosphorus. It is the most widely used cast iron, and its output accounts for more than 80% of the total output of cast iron.

 

Ductile iron Casting is obtained by spheroidizing and inoculation to obtain spheroidal graphite, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thereby obtaining higher strength than carbon steel. Ductile iron is a kind of high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. It is based on its excellent performance and has been successfully used for casting some complex forces, strength, toughness and wear resistance. Parts with higher requirements. Ductile iron has rapidly developed into a widely used cast iron material after gray cast iron. The so-called "iron-based steel" mainly refers to ductile iron.
