Question

The purpose of normalizing steel is

Answer 1

Normalization is a specific type of heat treatment that relieves stress on steel; this improves ductility and toughness in steels that may harden after the cold working process. ... After steel is heated to a temperature above its critical point, it is air-cooled until it drops to room temperature.

Answer 2

Normalizing aims to provide the steel with a uniform and high-quality-grained structure.

Explanation:

• The procedure is used to gain a predictable microstructure and a warranty of the steel's mechanical properties.
• Normalizing is a technique that improves element high-quality and performs an essential function in controlling dimensional variation in hardening and case hardening.
• It needs to be done each time dimensional stability is vital or while production operations are predicted to impart extensive amounts of stress into the material.
• metal is heated to a temperature under its melting point and allowed to cool in the air on the way to make it extra ductile
