EN 353 Steel Supplier in India | High-Quality Carburizing Steel from Jupiter Steels
Introduction to EN 353 Steel
EN 353 steel is a premium, low-carbon alloy steel known for its superior case hardening properties. As a carburizing grade, it is designed to achieve a very hard, wear-resistant surface while maintaining a tough and ductile core. This unique combination makes it ideal for components that require high surface hardness to withstand wear and fatigue, but also need a strong core to handle shock loads. At Jupiter Steels, based in Delhi, we are a trusted stockist and supplier of EN 353 steel, providing certified material to customers throughout India, including key industrial regions like Manesar, Haryana, and beyond.
Chemical Composition of EN 353 Steel
The reliable performance of EN 353 steel is a direct result of its carefully controlled chemical composition. The key alloying elements and their typical weight percentages are:
- Carbon (C): 0.15 – 0.20%
- Manganese (Mn): 0.35 – 0.60%
- Chromium (Cr): 0.70 – 1.00%
- Nickel (Ni): 1.00 – 1.50%
Functioning and Reasoning of Chemical Elements
- Nickel (Ni) & Chromium (Cr): This combination of alloying elements gives EN 353 steel its excellent hardenability and toughness. They allow the steel to be carburized and hardened effectively, forming a strong case while maintaining a tough core, which is essential for resisting impact and fatigue.
- Carbon (C): The low carbon content is key to this grade’s ability to be carburized. The core remains low in carbon, giving it its ductility, while the surface is enriched with carbon during heat treatment to achieve high hardness.
Hardness, Properties, and Applications of EN 353
Hardness
After the carburizing and heat treatment process, the surface of EN 353 steel can achieve a high hardness of 58-62 HRC, while the core remains softer, providing superior toughness.
Properties
- Superior Case Hardening: It is specifically designed for carburizing, allowing for a hard, wear-resistant surface.
- Excellent Core Toughness: The alloy content ensures the core remains highly ductile and tough, making it resistant to shock loading.
- Good Machinability: In its annealed condition, it can be easily machined into complex shapes before the final heat treatment.
- High Fatigue Strength: This is a critical property for components subjected to repeated stress cycles.
Applications
EN 353 steel is a versatile grade used for a wide range of components that require a combination of high surface wear resistance and core strength. Key applications include:
- Gears and Pinions
- Crankshafts
- Piston Pins and Spindles
- Connecting rods
- Heavy-duty shafts

EN 353 Steel FAQ Section
Q1: What is the main purpose of EN 353 steel?
A: The main purpose of EN 353 steel is to be case hardened through carburizing, which creates a very hard outer layer while keeping the inner core tough and ductile.
Q2: What makes EN 353 suitable for demanding applications?
A: The alloy content of EN 353 gives it superior core toughness and resistance to impact, making it ideal for parts that experience high loads and shock.
Q3: Can EN 353 be used in its as-supplied condition?
A: No, EN 353 steel is specifically designed for heat treatment. Its low carbon content provides insufficient strength and wear resistance in its annealed state for most applications.
