EN41B Grade Introduction:
EN41B is a 1.5% Chromium-Aluminum-Molybdenum nitriding steel, known for its excellent wear resistance and toughness. This low-carbon manganese-free steel is widely used for manufacturing components such as nuts, bolts, studs, and hydraulic fittings. It is ideal for parts requiring intricate machining, drilling, and enhanced wear resistance. EN41B is typically supplied in a hardened and tempered condition, offering a combination of toughness, ductility, and superior wear resistance.
This steel grade is suitable for nitriding, which improves its surface hardness up to 68 HRC, making it ideal for applications demanding high resistance to wear and abrasion.

EN41B Heat Treatment:
The heat treatment of EN41B includes controlling heating, soaking, and cooling rates depending on the shape and size of the component. Factors such as furnace type and quenching medium also play a role in heat treatment.
EN41B Hardening:
EN41B can be hardened by heating it to 930-970°C, followed by quenching in oil or water.
EN41B Tempering:
Tempering is done at 600-650°C, followed by air cooling.
EN41B Thermal Properties:
- Thermal Conductivity: 45 W/mK
- Coefficient of Thermal Expansion: 13.1 (0-250°C)
EN41B Forging Properties:
Forging of EN41B is performed at 850-1200°C, followed by slow cooling in sand.
EN41B Stress Relieving:
After heavy machining, stresses can be removed by heating to 700°C, equalizing, and cooling slowly.
EN41B Normalizing:
Normalizing is done by heating to 930-970°C and cooling in air.
EN41B Annealing:
Annealing is performed by heating to 840-870°C, followed by slow cooling in the furnace.
EN41B Density:
- Density: 8.08 g/cm³
EN41B Machinability:
EN41B alloy steel is readily machinable and suitable for producing complex parts.
EN41B Welding:
Welding is generally not recommended for EN41B due to its specific properties after nitriding.
