Q. Why we use cold working?
Cold working takes place below the recrystallization temperature, and therefore is fundamentally different at the atomic level with effects up to the macroscopic level.
Advantages of Cold Working
• No heating required.
• Close dimensional tolerances possible.
• Surface finishes are better.
• Strength, hardness, and directional properties are improved.
Disadvantages of Cold Working
• Produces stresses that sometimes have to be removed by heat treating.
• Higher forces and heavier equipment needed.
• Metal must be clean and scale free.
