3.1 Annealing

Process: Heat → soak → cool slowly (furnace cooling)
Result: Soft, ductile metal with relieved stresses
Use: For machining, cold working, or removing brittleness

Typical Applications

Automotive gears and shafts: carburized or quenched & tempered for wear resistance and core toughness.
Cutting tools: tool steels hardened and tempered for edge retention.
Bearings: through-hardened or case-hardened depending on load and wear.
Structural components: normalized or annealed to ensure toughness and predictable performance.

3. Hardening

This is the process of making the metal hard. The metal is heated above the critical temperature and then cooled rapidly (quenched) in a medium such as water, oil, or brine. Annealing : Annealing involves heating a metal to

The Science: The rapid cooling traps the carbon atoms within the iron crystal structure, forming Martensite, a very hard and brittle microstructure.
Challenge: While hardening increases strength, it makes the metal brittle and prone to cracking. This leads to the necessity of the fourth critical process.
