Which is false statement about annealing?
Annealing is done to
A. Relieve stresses
B. Harden steel slightly
C. Improve machining characteristic
D. Soften material
Answer: Option B
Solution(By Examveda Team)
Annealing of steels increased cold shaping possibilities because intermediate annealing can be utilized to improve the forming properties after the material is compressed during other operations such as cold heading.Annealing of steels reduced chance of distortion during secondary operations such as machining.
Annealing of steels controlled atmosphere annealing decreases the chance of oxidation to annealed parts.
Annealing of steels improved reaction time and greater control of emergency product need fulfillment.
