Heat Treatment Processes

Condenses and meanings of some common heat treatment processes like annealed, normalized, quench hardened and tempered are covered in this article.

Annealed:

Annealed in the state of a metal that has been heated above a particular temperature, depending upon its composition and then cooled down in the furnace itself or by covering it in ashes or lime. This annealing process makes the metal exceptionally delicate and flexible. Annealing usually procedure makes prior to flow-forming operations such as sheet metal pressing and wire tube drawing.

Normalized:

Normalizing is the state of a metal that has been heated above a particular temperature, depending upon its composition and then cooled down in free air. Despite the fact that the cooling is moderate, it isn’t concerning annealing so the metal is less delicate and malleable/ductile. This condition is more suitable for machining rather than for flow-forming. Normalizing is often used to stress relief castings and forgings after rough machining.

Quench hardened:

Quench hardened is the state of a metal that has been heated above a particular temperature, depending upon its composition and then cooled down very quickly-rapidly by immersing it in cold water or cold oil and the water or oil is called the quenching bath. Fast cooling by additives is called quenching. This rapid cooling from raised control temperatures makes the metal very hard. Only medium-carbon steels and high-carbon steels can be hardened in this way.

Tempered:

Quench-hardened steels are brittle as well as hard. To make them appropriate for cutting tools they have to be reheated to a predetermined temperature below 200 to 300ยฐC and do it again quenched. This makes them slightly less hard but very much tougher. Metals in this condition are said to be tempered.
