About EN19 VD Route And Annealed Forged Round Bar
EN19 steel, also known as 709M40 or AISI 4140, is a high-quality alloy steel known for its excellent tensile strength, ductility, and shock resistance. It is widely used in applications requiring high loading and wear resistance, such as gears, shafts, and spindles.
Key Features of EN19 Steel:
- Composition: EN19 steel typically contains 0.35-0.45% carbon, 0.50-0.80% manganese, 0.90-1.50% chromium, 0.20-0.40% molybdenum, and small amounts of silicon, sulfur, and phosphorus1.
- Mechanical Properties: It offers good tensile strength, typically around 850-1000 N/mm, and a yield strength of about 680-755 N/mm2.
- Heat Treatment: EN19 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.
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 properties1.
Annealed Round Bars:Annealed round bars of EN19 steel are heat-treated to relieve internal stresses and improve machinability. The annealing process involves heating the steel to a specific temperature (typically between 680-700C) and then slowly cooling it. This results in a softer and more ductile material, making it easier to machine and form4.
Applications:EN19 steel round bars are widely used in the manufacturing of:
- Gears
- Shafts
- Spindles
- Bolts
- Automotive components
- General engineering components
Exceptional Mechanical PropertiesThis round bar is engineered with high impact strength and excellent machinability, making it suitable for critical components in engineering, automotive, and construction applications. The annealed, non-magnetic state enhances its versatility and reliability under varying operational demands.
