About EN9 VD Route And Annealed Forged Round Bar
EN9 steel, also known by its trade name 070M55, is a medium carbon steel known for its good tensile strength and wear resistance. It is commonly used in applications requiring higher strength and durability, such as shafts, gears, and bolts.
Key Features of EN9 Steel:
- Composition: EN9 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 500-800 N/mm, and a yield strength of about 300-500 N/mm1.
- Heat Treatment: EN9 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.
VD Route: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:Annealed round bars of EN9 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.
Applications:EN9 steel round bars are widely used in the manufacturing of:
- Shafts
- Gears
- Bolts
- Studs
- Automotive components
- General engineering components
