C45 VD Route And Annealed Heavy Duty Forged Block

About C45 VD Route And Annealed Heavy Duty Forged Block

C45 steel is a medium carbon steel known for its good tensile strength and machinability. It is often used in applications requiring higher strength and wear resistance than mild steel, such as gears, bolts, and shafts.

• Composition: C45 steel typically contains 0.42-0.50% carbon, 0.50-0.80% manganese, and small amounts of silicon, sulfur, and phosphorus.
• Mechanical Properties: It offers good tensile strength, typically around 570-700 N/mm, and a yield strength of about 330-460 N/mm1.
• Heat Treatment: C45 can be heat treated to improve its mechanical properties. It is often supplied in the normalized or annealed condition to enhance its machinability and toughness2.

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 C45 steel are heat-treated to relieve internal stresses and improve machinability. The annealing process involves heating the steel to a specific temperature and then slowly cooling it. This results in a softer and more ductile material, making it easier to machine and form2.

C45 steel round bars are widely used in the manufacturing of:

• Gears
• Bolts
• Shafts
• Axles
• Studs
• General engineering components
