EN36 is a nickel–chromium–molybdenum alloy steel designed for high-strength, high-toughness applications where components must withstand heavy mechanical loads, impact, and fatigue. It is widely used in automotive, heavy engineering, and industrial machinery sectors. EN36 provides excellent wear resistance, ductility, and hardenability, making it suitable for gears, shafts, and structural components.

Key Properties of EN36 Steel

1. High Tensile Strength & Hardness

a. Tensile strength (normalized): 850–1000 MPa
b. Hardened & tempered: 40–50 HRC
c. Induction hardened surfaces: up to 55 HRC

2. Excellent Toughness & Fatigue Resistance

Suitable for parts exposed to cyclic loads, impact, and torsion.

3. Good Wear Resistance

Chromium and molybdenum provide strong abrasion resistance in mechanical components.

4. Deep Hardenability

Maintains uniform hardness in thick sections, ideal for shafts, axles, and gear blanks.

5. Good Machinability

Machinable in the normalized or annealed condition; becomes harder to machine after heat treatment.

6. Moderate Weldability

Preheating and post-weld heat treatment required due to alloy content.

Typical Applications of EN36

EN36 is widely used in automotive, aerospace, power transmission, and industrial machinery applications. Common components include:
1. Gear shafts, pinions & heavy-duty gears
2. Crankshafts, camshafts & connecting rods
3. Axles, spindles & propeller shafts
4. High-strength studs, bolts & fasteners
5. Drive shafts & couplings
6. Industrial machine components
7. Press tools & dies
8. Agricultural and construction machinery parts
9. Mining and heavy-duty mechanical components

Why Choose EN36?

EN36 is a versatile, high-strength alloy steel offering a balance of strength, toughness, wear resistance, and hardenability. Its ability to withstand mechanical shock and heavy loads makes it a preferred choice for high-performance shafts, gears, and critical machine components.
