La description

Good toughness. Impact value is more than *0 times of the grey iron materials .
Strong abilities to resist corruption. In the corrosion test, corrosion of this  is only 1/*0 of the steel tube, and  1/*0 of the grey iron pipe. Useful life is 2 times of grey iron pipe , and 5 times of ordinary steel pipe.
Good plasticity. Elongation of this is 7% or higher, same as  the high carbon steel material, and grey iron material’s elongation is zero.

  • High strength.tensile strength is the same as the low carbon steel material,  three times of gray iron material.
 
  • Because of the microstructure, nodular cast iron is better than cast steel in weakening vibration ability.
 
  • One important reason of choosing ductile iron is its lower cost. Nodular cast iron’s lower cost makes this kind of material more popular,  more efficient, less machining cost.
 
The strength of the nodular cast iron and cast steel strength is comparable. Ductile cast iron has higher yield strength, the yield strength minimum of *0 k, and cast steel yield strength only *6 k. In most municipal application fields, such as: water, salt water, steam, etc., corrosion resistance and oxidation resistance of ductile iron are more than cast steel.
