Grade EN 41B
EN 41B is a high-carbon, high-tensile engineering steel widely used in heavy machinery, automotive, and industrial applications. It is designed for components that require high strength, hardness, and wear resistance while maintaining moderate toughness. This grade is known for its durability, reliability, and cost-effectiveness in medium-to-heavy load-bearing applications.
EN 41B is often supplied in normalized or annealed condition and can be heat-treated to increase hardness and wear resistance, making it suitable for shafts, gears, pins, and high-load machine parts.
Key Properties of EN 41B
1. High Strength & Durability
Provides excellent tensile and yield strength, suitable for shafts, pins, and structural components.2. Moderate Toughness
Tough enough for moderate-impact applications while maintaining wear resistance.3. Good Wear Resistance
High carbon content allows for hardening by heat treatment, improving abrasion and friction resistance.4. Heat Treatable
a. Normalized hardness: 200–250 HB
b. Quenched & tempered: 45–55 HRC (surface hardness depending on treatment)
5. Good Machinability
Easy to machine in normalized or annealed condition; becomes harder after heat treatment.6. Moderate Weldability
Welding is possible with proper preheating and post-weld stress relief.Typical Applications of EN 41B
1. Shafts, axles, and spindles
2. Pins, studs, and fasteners
3. Gears, sprockets, and couplings
4. Machine tool components
5. Agricultural and construction machinery parts
6. Rollers, levers, and heavy-duty mechanical components
7. Press and forging tools (medium load)
