What is the primary purpose of normalizing in steel manufacturing?

• To increase ductility
• To produce a fine grain size
• To enhance rust resistance
• To decrease toughness

When normalizing steel components, what temperature range is typically used for heating?

• 100-200°C above the upper critical temperature
• 10-20°C above the lower critical temperature
• 30-40°C above the upper critical temperature
• Room temperature

Which of the following is NOT a purpose of normalizing in steel manufacturing?

• Stress and strain removal
• Fine grain size production
• Increasing ductility
• Preventing warping

What is the recommended cooling medium for normalizing steel components?

• Water
• Oil
• Still air
• Liquid nitrogen

When should normalizing be applied in steel manufacturing processes?

• Only to castings
• After forging and work hardening
• After quenching in water
• Only to high-carbon steel
