Characteristics of nodular cast iron manhole cover:
1. High strength Ductile iron has a tensile strength of more than 420 MPa and a yield strength of more than 300 MPa. It is the same as low carbon steel and is three times that of gray iron.
2. Good resistance The impact value is similar to that of carbon steel, which is 10 times that of gray iron.
3. Good plasticity. The ductility elongation is greater than 7%. Similar to high carbon steel, the elongation of gray iron data is zero.
4. Corrosion resistant. The 90-day spray corrosion test and the 0.1-time gray iron pipe corrosion were only 0.25 times that of the pipe. The service life is 2 times longer than the gray iron pipe and 5 times longer than the ordinary steel pipe.
In most municipal applications, such as water, brine, steam, and cast iron, corrosion resistance and oxidation resistance are superior to steel. Due to the microstructure of spherical graphite cast iron, ductile iron is superior to steel in reducing the oscillation capacity.
Advantages of ductile iron manhole covers:
1. The ductile iron manhole cover is mainly made of ductile iron, or ductile iron or iron. Whether the quality is good or bad depends on the nodule. Corrosion-resistant asphalt paint is usually used in the casting process; the surface of the ductile iron manhole cover is treated with a sprayed asphalt anti-rust coating.
2. Low cost is an important reason why cast iron is more affordable than steel, which makes ductile iron more popular. The casting power is higher and the processing cost of ductile iron is lower.
3. The ductile iron manhole cover has another strength. The ductile iron has high strength and durability, so that the ductile iron manhole cover is about 30% lighter than the gray cast iron manhole cover.
