DN700 ductile cast iron Double

The advantages of ductile iron manhole cover

The more familiar name for ductile iron is ductile iron or ductile iron. The flake graphite in cast iron will change into the shape of spheroidal graphite after adding metallic magnesium, which greatly improves the tensile strength, seismic resistance and elongation of the metal.

Comparison of nodular cast iron and gray cast iron:

Because of the weight / strength ratio of nodular cast iron, manhole covers made of nodular cast iron are 20% -30% lighter than the same products made of gray cast iron.

Therefore, the transportation cost is reduced, the manhole cover is easy to handle, and the ductile iron has welding performance (gray cast iron cannot be welded).
