EN 9 Bright Bars
EN 9 Bright Bar Chemical Composition
EN 9 is a British Standard for a medium carbon steel alloy typically used in producing bright bars. The standard specifies the chemical composition of the material, which includes:
Carbon (C) : 0.50-0.60 %
Manganese (Mn) : 0.60-0.90 %
Silicon (Si) : 0.15-0.35 %
Sulfur (S) : 0.050% max
Phosphorus (P) : 0.050% max
The standard also specifies the maximum permissible levels of other elements such as aluminum, chromium, nickel, and lead, which should be less than 0.050% each.
EN 9 bright bar is used in a wide range of industrial applications such as gears, shafts, pins, bushings, fasteners and many more. It is also known for its ductility, toughness, and wear resistance.
It’s worth noting that the chemical composition can vary depending on the specific condition (such as heat treatment) of the material
