Cold Drawn Steel Bright Bars (Dia 17mm to 63.50mm) – EN 10083-2 C40E

Cold drawn steel bright bars made from EN 10083-2 C40E steel are widely used in various engineering applications due to their excellent mechanical properties and uniform surface finish. These bars are produced by cold drawing, a process that improves dimensional accuracy and surface finish, making them ideal for applications requiring tight tolerances and high strength. With a diameter range of 17mm to 63.50mm, these bars are commonly used in the manufacturing of shafts, bolts, gears, and other machine components.

Key Features:

  • Diameter Range: 17mm to 63.50mm
  • Superior Surface Finish: Smooth, shiny surface ideal for high-precision applications.
  • Enhanced Strength and Durability: High carbon content improves strength and wear resistance.
  • Applications: Engineering, automotive, and manufacturing industries.

Chemical Composition of EN 10083-2 C40E:

Element Percentage (%)
Carbon (C) 0.37 - 0.44
Silicon (Si) 0.10 - 0.35
Manganese (Mn) 0.60 - 0.90
Phosphorus (P) ≤ 0.035
Sulfur (S) ≤ 0.035
Chromium (Cr) ≤ 0.25
Nickel (Ni) ≤ 0.30
Copper (Cu) ≤ 0.25
Aluminium (Al) ≤ 0.10

These chemical properties contribute to the steel's hardness, tensile strength, and good machinability.
