About EN31 VD Route And Annealed Heavy Duty Forged Shaft

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

Outstanding Forging and Annealing Method

The EN31 heavy-duty shaft is produced via open or closed die forging, then annealed through a VD route-controlled process. This ensures thorough refinement of the microstructure, leading to enhanced crack resistance and consistent properties throughout the product.

Precision You Can Trust

Each shaft meets tight DIN precision tolerances and undergoes comprehensive ultrasonic testing. This strict quality control ensures high dimensional accuracy, superior impact strength, and allows for reliable performance even under challenging operating conditions.

Flexible and Custom Solutions

Bar lengths can be custom cut to your requirements, and flexible minimum order quantities make it simple for businesses of all sizes to order. We offer OEM support, various edge conditions, and export-grade packaging for safe global delivery.
