Product Introduction

What is the material of ductile iron?

Ductile iron is a kind of high strength cast iron material developed in the 1950s, its comprehensive performance is close to steel, it is based on its excellent performance, has been successfully used to cast some complex forces, strength, toughness, wear resistance requirements of high parts. Ductile iron has rapidly developed into a cast iron material second only to gray iron and widely used. The so-called "iron instead of steel" mainly refers to ductile iron.

Nodular cast iron is obtained by spheroidization and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the ductility and toughness, so as to obtain higher strength than carbon steel.

Thank you for choosing our products. We look forward to serving you with the best of our abilities.

Ductile cast iron sewer cover is a kind of ductile iron product, ductile cast iron by spherization and breeding processing obtained ball graphite, effectively improve the mechanical engergy of cast iron, especially improve the plasticity and toughness, thus get the strength that is higher than carbon steel. Ductile cast iron was a high degree iron casting material that was exhibited in the 20^th century, which is close to steel, which is based on its excellent performance and has been successfully used to create some parts that are complex, strong, resilient and wear-resistant, Ductile cast iron has been rapidly developed second only to grey cast iron and is widely used in cast iron materials. It is called”iron generation steel”, mainly ductile iron, Ductile cast iron is divided into circular and square, in urban road management, generally adopt round manhole cover, because round manhole cover is not easy to tilt, can be better protect the safety of pedestrians and vehicles, using the circle manhole cover is mainly considered that the round manhole cover same diameter, when the hole is rolled up, it will be slightly wider than the hole in the bottom and the lid will not fall into the well.

And if you use the square manhole cover, because the diagonal is significantly longer than each of the edges, it’s easy to fall into the well along the diagonal direction of the well and cause safety risks.

In the countryside and cable Wells, square is generally used, which can better prevent the entry of liquids such as rain.
