Heat Treatment
To enhance mechanical performance, 45C8 steel can undergo different heat treatment processes.
- Hardening: Heat between 820°C and 860°C, followed by oil or water quenching.
- Tempering: Temper within the range of 550°C to 660°C to improve toughness while reducing brittleness.

| Thermal Expansion | 11 µm/m°C |
| Thermal Conductivity | 49.8 W/mK |
Forging
45C8 steel is generally forged within a temperature range of 1100°C to 850°C and allowed to cool naturally in air to achieve optimum grain structure.
Stress Relieving
Stress relieving is often carried out after machining or welding to minimize residual stresses and improve dimensional stability.
Normalizing
Normalizing is performed by heating the steel to 840°C–880°C, followed by air cooling. This process refines the grain structure and enhances mechanical properties.
Annealing
For improved machinability, the material can be annealed by heating to 680°C–710°C and then slowly cooled inside the furnace.
Machinability
45C8 offers good machining characteristics with an approximate machinability rating of 55% when compared with AISI 1212 free-cutting steel. It is suitable for turning, drilling, milling, and other precision machining operations.
Welding
Although 45C8 can be welded, proper precautions are recommended. Controlled preheating, gradual cooling, and post-weld heat treatment help reduce the risk of cracking and improve weld quality. Tempering after welding is generally advised to relieve residual stresses.
