C55 VD Route And Annealed Forged Shaft

Product Description

C55 steel is a medium carbon steel known for its good tensile strength and wear resistance. It is often used in applications requiring higher strength and durability, such as gears, shafts, and bolts.

• Composition: C55 steel typically contains 0.50-0.60% carbon, 0.50-0.80% manganese, and small amounts of silicon, sulfur, and phosphorus1.
• 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: C55 can be heat treated to improve its mechanical properties. It is often supplied in the normalized or annealed condition to enhance its machinability and toughness1.

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 properties3.

Annealed round bars of C55 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 form1.

C55 steel round bars are widely used in the manufacturing of:

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