EN8/EN9 En Series Round Steel Bar

EN8 is a medium carbon steel with a carbon content of 0.25% to 0.60%. It is often used to manufacture mechanical parts, bearings, gears and other parts. It has high strength and wear resistance and can obtain high hardness and strength after heat treatment. The chemical composition of EN8 includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements. The carbon content is the most important, usually between 0.36-0.44%. EN8 has good weldability, and it can be welded by conventional welding methods, such as arc welding, gas welding, etc. However, when performing high-intensity welding, care needs to be taken to control the welding heat to prevent material deterioration. EN8 carbon steel bars are widely used in the manufacturing industry, especially where high strength and wear resistance are required. They are often used to manufacture bearings, pins, mechanical parts, etc..
