A) Drawing
B) Cyaniding
C) Normalizing
D) Tempering

Question

Quizplus · Accepted Answer

Normalizing is a heat treatment process that involves heating the steel to a temperature above its critical temperature and then cooling it in air. This process refines the grain structure of the steel, improves its ductility and toughness, and reduces its hardness. It is often performed on medium- and high-carbon steels prior to hardening to achieve a more uniform microstructure and prevent cracking during the hardening process. Drawing, cyaniding, and tempering are other heat treatment processes that are typically performed after hardening to improve the steel's properties.
