Question

What is the process in steel to relieve strain and stress to eliminate hardness and improve the machineability?​

Answer 1

Answer:

Sub-Critical Annealing is a relatively low temperature heat treating process used to reduce hardness and increase ductility. This process improves machinability and reduces stress, to decrease the likelihood of cracking during cold working operations.

Answer 2

Sub critical annealing is a relatively low temperature heat treating process used to reduce hardness and increase ductility.
