It is important that the manhole cover cast material has both aesthetic and sanitary value. In this case, knowledge of the strength of the material is required. Here we will discuss ductile cast iron, which has many properties in casting manhole covers. So what makes BIC India’s ductile iron superior to other metals when casting manhole covers?

Ductile Iron Manhole Cover India is mainly made of ductile iron or called ductile iron or nodular iron. Good or bad quality depends on modularity. The pouring process generally uses asphalt anti-corrosion paint. Manhole covers made of ductile iron are surface-treated by spraying asphalt anti-rust paint.

The tensile strength of ductile cast iron is more than four hundred twenty MPa and the yield strength is more than three hundred MPa, which is comparable to low carbon steel and three times that of gray cast iron.

Impact strength is comparable to carbon steel and ten times higher than gray cast iron. It has a ductile elongation of seven percent or more, similar to carbon steel and gray cast iron materials, but no elongation.

Corrosion is a natural process that degrades metals. Corrosion has many causes to occur, and our product stands out against it because we used the best material to create ductile iron manhole covers in India. A 90-day spray corrosion test was only one-fourth of the pipe and 0.1 times that of gray cast iron pipe. The service life is twice that of cast iron pipes and five times that of ordinary steel pipes.

For most urban applications such as water, salt water, and steam, cast iron is more resistant to corrosion and oxidation than steel. The microstructure of ductile iron makes it superior to steel in terms of reduced vibration capacity, making it the best ductile iron manhole covers in India. Low cost is a major reason why cast iron is much more acceptable than steel, and ductile iron is becoming more popular. Casting ductile iron is more efficient and costs less to the machine. Ductile iron manhole covers have another advantage. Due to the high strength and toughness of ductile iron, ductile iron manhole covers are approximately thirty percent lighter than the same type of gray cast iron manhole covers.

A ductile iron manhole cover is one of BIC India’s main products. There is no doubt that ductile iron manhole covers play an important role in day-to-day construction activities.
