About EN31 VD Route And Annealed Rolled Round Bar

EN31 steel, also known as SAE 52100, is a high-carbon alloy steel known for its excellent hardness, compressive strength, and abrasion resistance. It is widely used in applications requiring high wear resistance and durability, such as bearings, tools, and machine components.

Key Features of EN31 Steel:

Composition: EN31 steel typically contains 0.95-1.10% carbon, 0.40-0.70% manganese, 1.20-1.60% chromium, and small amounts of silicon, sulfur, and phosphorus1.
Mechanical Properties: It offers high tensile strength, typically around 750-800 N/mm, and a yield strength of about 450-500 N/mm2.
Heat Treatment: EN31 can be heat treated to improve its mechanical properties. It is often supplied in the 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 EN31 steel are heat-treated to relieve internal stresses and improve machinability. The annealing process involves heating the steel to a specific temperature (typically around 800C) and then slowly cooling it. This results in a softer and more ductile material, making it easier to machine and form2.

Applications:

EN31 steel round bars are widely used in the manufacturing of:

Bearings
Tools
Machine components
Shafts
Gears

High-Performance Annealed Rolled Bars

EN31 Round Bars deliver consistent performance due to their carefully controlled annealed rolled process. This treatment enhances machinability, making the bar an excellent choice for applications demanding precise mechanical properties and durability.

Versatile Industrial Usage

Thanks to its fine pearlitic structure and robust characteristics, EN31 bars are the preferred choice for making components like shafts, gears, bearings, and roller parts. The low nickel content and magnetic properties also add versatility across different industrial sectors.

Reliable Protection & Packaging

To ensure the bars reach customers in optimal condition, each round bar is provided with a rust-preventive coating and is shipped bundled or loose as per requirement. This minimizes surface degradation and ensures longevity during handling and storage.

FAQ's of EN31 VD Route And Annealed Rolled Round Bar:

Q: How is the EN31 VD Route and Annealed Rolled Round Bar processed?

A: The bar undergoes vacuum degassing (VD Route) followed by annealed rolling, which refines its microstructure to a fine pearlitic form and enhances machinability and toughness.

Q: What are the main uses of EN31 Round Bars in industry?

A: These bars are commonly used in the manufacturing of automotive components, bearings, shafts, gears, and tools where high wear resistance and durability are critical.

Q: When should I choose annealed rolled round bars over other finishes?

A: Annealed rolled bars are ideal for applications requiring good machinability, uniform mechanical properties, and a smooth surface, making them suitable for further processing and precision engineering tasks.

Q: Where can I purchase EN31 VD Route and Annealed Rolled Round Bars in India?

A: You can acquire these bars from a range of dealers, distributors, exporters, importers, manufacturers, suppliers, and other service providers across India.

Q: What is the benefit of the rust preventive coating on EN31 round bars?

A: The rust preventive coating protects the bar from corrosion during storage and transportation, ensuring that the material maintains its integrity and is ready for use upon delivery.

Q: Is EN31 Round Bar suitable for welding purposes?

A: EN31 round bars have limited weldability due to their alloy composition and fine pearlitic microstructure, so welding should be done only if necessary and with proper precautions.
