EN 47 Steel Supplier in India | Your Partner for High-Quality Spring Steel
Introduction to EN 47 Steel
EN 47 steel is a popular chromium-vanadium spring steel known for its excellent combination of high tensile strength, toughness, and superior fatigue resistance. This versatile grade is specifically designed for applications that require resilience and the ability to withstand repeated stress and shock loading without permanent deformation. Its unique alloy content makes it a superior choice for a wide range of springs and other components. At Jupiter Steels, based in Delhi, we are a trusted stockist and supplier of EN 47 steel, providing certified material to customers throughout India, including key industrial regions like Manesar, Haryana, and beyond.
Chemical Composition of EN 47 Steel
The reliable performance of EN 47 steel is a direct result of its carefully controlled chemical composition. The key alloying elements and their typical weight percentages are:
- Carbon (C): 0.45 – 0.55%
- Manganese (Mn): 0.70 – 1.00%
- Chromium (Cr): 0.80 – 1.10%
- Vanadium (V): 0.15 – 0.25%
- Silicon (Si): 0.10 – 0.40%
Functioning and Reasoning of Chemical Elements
- Chromium (Cr) & Vanadium (V): This combination of alloying elements is the core of EN 47 steel. Chromium enhances its hardenability and provides resistance to wear. The addition of vanadium significantly refines the grain size of the steel, which is critical for improving its fatigue strength and toughness.
- Medium Carbon (C): The carbon content provides the necessary strength and hardness, allowing the steel to be heat-treated to achieve its required elastic properties.
Hardness, Properties, and Applications of EN 47
Hardness
After heat treatment, EN 47 steel can achieve a high working hardness, typically in the range of 40-45 HRC, which is crucial for spring applications.
Properties
- High Tensile Strength: It provides the necessary strength to withstand significant loads.
- Superior Fatigue Resistance: This is its most well-known property. It can endure repeated stress cycles without failing, which is the key requirement for all spring applications.
- Good Toughness: It provides a good balance of strength and toughness, which is crucial for resisting impact loads.
- Good Machinability: In its annealed condition, it can be easily machined before the final heat treatment.
Applications
EN 47 steel is a versatile grade used for a wide range of spring and highly stressed components. Key applications include:
- Leaf Springs for automobiles and heavy vehicles
- Coil Springs
- Shafts and Axles
- Torsion Bars
- General engineering components that require high resilience and fatigue strength.
