Ball mill cast iron

The strength of ductile iron is comparable to that of cast steel. Ductile iron has higher yield strength, and its yield strength is at least 40k, while cast steel's yield strength is only 36k. In most municipal applications, such as water, salt water and steam, ductile iron is more resistant to corrosion and oxidation than cast steel. Because of the spheroidal graphite microstructure of ductile iron, ductile iron is superior to cast steel in reducing vibration, so it is more beneficial to reduce stress. An important reason to choose ductile iron is that ductile iron is cheaper than cast steel. The low cost of ductile iron makes it more popular, more efficient and less expensive to process.

Ductile iron is obtained by spheroidizing gray cast iron water, and the precipitated graphite is spherical, or ductile iron for short. All or most of the carbon exists in free-form spheroidal graphite, broken silver gray. Compared with ordinary grey cast iron, it has higher strength, better toughness and plasticity. The plate number is denoted by "QT" followed by two sets of Numbers, for example, qt45-5 (the first set represents the lowest tensile strength, and the second group represents the lowest elongation). Used to manufacture internal combustion engines, auto parts and farm tools, etc.

Vermicular cast iron. The graphite precipitated from gray cast iron was obtained by creep treatment. The mechanical properties are similar to nodular cast iron, and the casting properties are between grey cast iron and nodular cast iron. Used to make auto parts.
