EN8D Carbon Steel
Grade Introduction:
EN8D is a grade commonly used for making high-strength steel components. It is a medium carbon steel that is characterised by its high ductility and machinability. EN8D steel bars have a carbon content of 0.40-0.45% and a manganese content of 0.70-0.90%.
EN8D steel bars are known for their excellent mechanical properties, including high tensile strength, good wear resistance, and good fatigue resistance. They are also known for their good machinability and weldability. These properties make EN8D steel bars suitable for use in various applications, including the construction of machinery and equipment, automotive components, and other high-strength steel structures.
EN8D steel bars are also known for their good surface finish and dimensional accuracy, which makes them suitable for use in precision engineering applications.
EN8D steel bars are typically supplied in the as-rolled condition, but they can also be supplied in the heat-treated condition. The heat treatment process can improve the mechanical properties of the steel, making it even stronger and more wear resistant.
It is one of the most used grades of carbon steel. People requiring better properties such as strength, etc., generally go for alloy steels if En8d or equivalent grades are not suitable.
