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

Superior Microstructure and Quality

EN31 round bars are engineered for precision and strength, offering a uniform fine grain structure due to the VD Route. This ensures exceptional toughness, reliability during usage, and consistent material performance-making them well-suited for demanding engineering tasks.

Versatile Applications with Ready Availability

With stock in standard sizes and flexible minimum order quantities, these round bars cater to diverse sectors like automotive, toolmaking, and general engineering. Their bright finish and excellent machinability ensure ease of secondary processing, while suppliers across India guarantee prompt delivery and services.
