Ductile iron round manhole covers / Lightweight ductile iron manhole covers / GCD450
Ductile iron manhole covers are a type of ductile iron product. Ductile iron is produced through spheroidal graphite treatment and inoculation, resulting in spherical graphite structures that significantly enhance the material's mechanical properties—particularly its ductility and toughness—thus achieving strength levels even higher than those of carbon steel. Developed in the 1950s, ductile iron is an ultra-high-strength cast iron material whose overall performance closely rivals that of steel. Thanks to these outstanding characteristics, it has been successfully used to manufacture complex components that demand high strength, excellent toughness, and superior wear resistance. Today, ductile iron has rapidly emerged as the second most widely used cast iron material after gray iron. The concept of "replacing steel with iron," when applied to engineering applications, primarily refers to the use of ductile iron.
