Performance:

Ductile iron castings have been applied in almost all major industrial sectors, which require high strength, plasticity, toughness, wear resistance, and resistance to severe thermal and mechanical impacts.

High or low temperature resistance, corrosion resistance, and dimensional stability. In order to meet these changes in service conditions, there are many grades of nodular cast iron, which provide

A very wide range.

As specified in International Organization for Standardization ISO1083, most ductile iron castings are mainly produced in unalloyed state. Obviously, this range includes tensile strength of up to 800 tons

The material commonly used for high-strength grade ductile iron manhole covers with a elongation of 2% is QT500-7 and a Brinell hardness of 170-230HB. The other extreme is the high plasticity grade, which

The elongation rate is 17%, while the corresponding strength is relatively low (with a minimum of 370 Newton/meter spoon). Strength and elongation are not the only factors that designers choose materials, but other decisive factors are important

The component performance also includes yield strength, elastic modulus, wear resistance and labor strength, hardness, and impact performance. In addition, corrosion resistant components, oxidation resistance, and electromagnetic performance may be crucial for dry designers

Key. In order to meet these special needs, a set of austenitic ductile iron, commonly known as Ao Ni Resis dead ductile iron, has been developed. These austenitic ductile irons are mainly metallized with zinc, chromium, and manganese.
