About EN19 VD Route And Annealed Heavy Duty 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

FAQ's of EN19 VD Route And Annealed Heavy Duty Forged Round Bar:
Q: How is the EN19 VD Route and Annealed Forged Round Bar manufactured?
A: The bar is produced using a heavy duty forging method, followed by vacuum degassing (VD) and an annealing thermal treatment. This process helps refine the grain structure, relieves internal stresses, and improves overall performance.
Q: What benefits does the annealed delivery condition provide?
A: Annealing enhances the machinability of the bar, making it easier to process in subsequent manufacturing steps. This heat treatment also boosts impact strength and reduces brittleness, offering improved toughness for heavy-duty applications.
Q: When is stock available and what is the lead time for delivery?
A: Stock is available on order, and the lead time is determined based on the specifics of each order. Suppliers work closely with customers to ensure timely delivery tailored to the project's requirements.
Q: Where can EN19 VD Route and Annealed Round Bars be supplied from?
A: These round bars are manufactured, distributed, and supplied by a network of dealers, exporters, importers, and retailers across India. They are also available for global export.
Q: What testing and quality control measures are performed on the bars?
A: Each bar undergoes ultra-sonic and crack testing to ensure there are no internal or surface defects. Strict adherence to roundness tolerance and edge smoothness further guarantees product quality.
Q: How can these bars be used in industrial applications?
A: Owing to their high impact strength, tight tolerances, and smooth condition, these bars are ideal for components in heavy machinery, automotive parts, shafts, spindles, and other mechanically demanding scenarios.
