Answer is:
Annealing
Explanation:
The annealing process is carried out by heating the steel above the critical range, soaking it for sufficient time to allow the necessary changes to occur, and cooling at a predetermined rate, usually very slowly, within the furnace.
Answer is:
It was suddenly cooled in brine
Explanation:
It was suddenly cooled in brine in heat treatment, this is the main reason for the component to crack after heat treatment.
Answer is:
Low-carbon steel parts
Explanation:
Case-hardening or surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal (called the "case") at the surface.
Normally Low carbon steel parts are subjected to case hardening process.
