About En41b VD Route And Annealed rolled round bar

EN41B steel is a high-quality alloy steel known for its excellent wear resistance, toughness, and ductility. It is commonly used in applications requiring high surface hardness and strength, such as gears, shafts, and other high-stress components.

• Composition: EN41B steel typically contains 0.35-0.45% carbon, 0.50-0.80% manganese, 1.00-1.40% chromium, 0.15-0.25% molybdenum, and 0.85-1.20% aluminum1.
• Mechanical Properties: It offers good tensile strength, typically around 700-850 N/mm, and a yield strength of about 450-600 N/mm2.
• Heat Treatment: EN41B can be heat treated to improve its mechanical properties. It is often supplied in the normalized or annealed condition to enhance its machinability and toughness3.

The Vacuum Degassing (VD) route is a steelmaking process that removes dissolved gases like hydrogen and nitrogen from the molten steel. This process improves the steels quality by reducing the risk of defects and enhancing its mechanical properties1.

Annealed round bars of EN41B steel are heat-treated to relieve internal stresses and improve machinability. The annealing process involves heating the steel to a specific temperature (typically around 680-700C) and then slowly cooling it. This results in a softer and more ductile material, making it easier to machine and form3.

EN41B steel round bars are widely used in the manufacturing of:

• Gears
• Shafts
• Spindles
• Bolts
• Automotive components
• General engineering components
