Corrosionpedia What is Normalizing? Definition from

Normalizing permits the refinement of a metal's grain size and improves the metal's mechanical properties. Normalizing gives steel a uniform and fine grained structure. This uniformity in the chemical and physical properties of an alloy is most important after it

Annealing and normalising GH INDUCTION

In general, the main purpose of annealing heat treatment is to soften the steel, regenerate overheated steel structures or just remove internal tensions. It basically consists of heating to austenitizing temperature (800ºC and 950ºC depending on the type of steel), followed by slow cooling. Normalizing. Normalization is an annealing process.

Tempering (metallurgy) Wikipedia

Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal. Tempering is usually performed after quenching, which is rapid cooling of the metal to put it in its
