16MnCr5 is a low-carbon case-hardening steel known for its excellent wear resistance, high surface hardness after carburizing, and good toughness in the core. It is widely used in the manufacture of components requiring a hard surface and strong core. At Steelmet Industries, we manufacture and supply 16MnCr5 steel bars in hot rolled, bright, and custom-profiled forms, made from tested and traceable material to meet the most demanding applications.

⚙️ Applications of 16MnCr5 Steel
16MnCr5 is a preferred steel for parts that undergo carburizing and require a combination of:
-
High wear resistance at the surface
-
Good core toughness and fatigue strength
Common applications include:
-
Transmission gears and shafts
-
Gearbox components
-
Bushings and sprockets
-
Pinions and rings
-
Timing gear components
-
Construction and agricultural machinery parts
-
Automotive driveline components
🔧 Machinability, Weldability & Heat Treatment
-
Machinability: Good in soft-annealed or normalized state
-
Weldability: Moderate – Preheating is recommended for thick sections
-
Heat Treatment Options:
-
Carburizing: 870–950°C
-
Hardening: 800–820°C followed by oil quenching
-
Tempering: 150–200°C (to relieve stresses post-hardening)
-
Annealing: ~680–710°C
-
Normalizing: ~870–900°C
-
The steel responds well to deep case hardening, making it suitable for wear-critical components.
