Steelo Fabrica is a leading Manufacturer, Exporter, and supplier of premium quality EN-47 Round Bars/Rods.
What is EN-47?
EN47 is a Spring Steel which is supplied in the rolled situation. This Spring steel is used for oil hardening and tempering. En47 combines spring characteristics with good wear and abrasion resistance. When the material is hardened, It offers excellent toughness and shock resistance, making it a suitable alloy spring steel for parts exposed to stress, shock, and vibration.

What are EN-47 Round bars?
EN47 round bar is pure medium carbon steel with the best tensile power compared to normal mild steel. EN 47 Round Bar is a Chromium Vanadium Spring Steel (which contains approx. 0.50 carbon). Generally, It is the best quality steel which provides good wear resistance after heat treatment. EN 47 Round Bar has a high ratio of yield point to tensile strength and high torsional fatigue strength.
What are EN-47 Rods?
EN47 rod, too, is a pure medium carbon steel used in applications where improved characteristics than mild steel are necessary but where the costs do not defend the purchase of a steel alloy.
Properties of EN-47 Bars:
When EN47 round bar has another feature, it exhibits excellent shock wave resistance and toughness, making it an ideal alloy spring for parts exposed to heavy loads and vibratiaon. Other properties include excellent finishing, resistance to rust, durability, tensile strength.
Application of the EN -47 Round Bars and rods:
EN47 round bars are used widely in the motor vehicle industry and many general engineering applications. It is suitable for applications that require high tensile strength and rigidness. The proper usages include crankshafts, steering knuckles, gears, spindles, and pumps.
Also, other uses are tractors, heavy vehicles, stress and the diameter of the larger plate spring, industrial production load, and helical spring. It is also used widely in many general engineering applications.
