EN 18 Steel Supplier in India | High-Quality Spring Steel from Jupiter Steels
Introduction to EN 18 Steel
EN 18 steel is a popular and versatile spring steel known for its excellent combination of high resilience, toughness, and fatigue resistance. It is a chromium alloy steel that can be heat-treated to achieve a high strength-to-weight ratio, making it ideal for components that are subjected to repeated stress and shock loads. At Jupiter Steels, based in Delhi, we are a trusted stockist and supplier of EN 18 steel, providing certified material to customers throughout India, including key industrial regions like Manesar, Haryana, and beyond.
Chemical Composition of EN 18 Steel
The reliable performance of EN 18 steel is a direct result of its carefully controlled chemical composition. The key alloying elements and their typical weight percentages are:
- Carbon (C): 0.50 – 0.60%
- Chromium (Cr): 0.90 – 1.20%
- Manganese (Mn): 0.50 – 0.80%
- Silicon (Si): 0.10 – 0.40%
Functioning and Reasoning of Chemical Elements
- Chromium (Cr): The chromium content in EN 18 enhances the steel’s hardenability and tensile strength. This allows the steel to be heat-treated to a high hardness, which is critical for its function as a spring steel.
- Carbon (C): The high carbon content is the primary reason for this steel’s ability to achieve high hardness after heat treatment, which provides the necessary strength and resilience.
Hardness, Properties, and Applications of EN 18
Hardness
After hardening and tempering, EN 18 steel can achieve a wide range of working hardness, typically in the range of 40-50 HRC, which gives it the necessary spring properties.
Properties
- High Resilience: It can be deformed under load and return to its original shape, which is the defining property of a spring steel.
- Good Toughness: It provides a good balance of strength and toughness, allowing it to withstand shock and impact without breaking.
- High Fatigue Resistance: It holds up well under repeated stress cycles, which is critical for springs and other dynamic components.
- Good Machinability: In its annealed condition, it can be easily machined into complex shapes before the final heat treatment.
Applications
EN 18 spring steel is a versatile grade used for a wide range of components that are subjected to dynamic loads. Key applications include:
- Leaf Springs and Coil Springs
- Helical Springs
- Shafts and Axles for moderate loads
- Spring Washers
- Agricultural implements
- Clamping components
