EN 18 Steel Supplier in India | Your Partner for High-Strength Alloy Steel
Introduction to EN 18 Steel
EN 18 steel is a popular chromium alloy steel known for its excellent combination of good tensile strength, toughness, and fatigue resistance. This versatile grade is widely used in engineering applications that require a balance of high strength and durability. It is a highly reliable material for components that will be subjected to moderate stress and wear. 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): 0.35 – 0.45%
- Manganese (Mn): 0.70 – 1.00%
- Chromium (Cr): 0.80 – 1.10%
- Silicon (Si): 0.10 – 0.40%
- Sulfur (S): Max 0.05%
- Phosphorus (P): Max 0.05%
Functioning and Reasoning of Chemical Elements
- Chromium (Cr): The addition of chromium is the core of EN 18 steel. It significantly enhances its hardenability and provides resistance to wear and abrasion, which is crucial for its application in stressed components.
- Medium Carbon (C): The carbon content provides the necessary strength and hardness, allowing the steel to be heat-treated to achieve its required mechanical properties.
- Manganese (Mn): Manganese improves the steel’s hardenability and tensile strength.
Hardness, Properties, and Applications of EN 18
Hardness
In its hardened and tempered condition, EN 18 steel typically has a hardness in the range of 250-300 HB, which provides a great balance of strength and toughness. It can be heat-treated to higher hardnesses for specific applications.
Properties
- Good Tensile Strength: It provides sufficient strength for a wide range of engineering components.
- High Fatigue Resistance: Its properties make it a good choice for parts that undergo repeated loading and unloading.
- Good Toughness: It provides a good balance of strength and toughness, which helps to prevent brittle fracture.
- Excellent Hardenability: It can be through-hardened, ensuring uniform properties through its cross-section.
Applications
EN 18 steel is a versatile grade used for a wide range of engineering components. Key applications include:
- Shafts and Axles
- Gears and Spindles
- Studs and Bolts
- Automotive components
- General structural parts and forgings
