Heat treating Wikipedia

Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve the desired result such as hardening or softening of a material. Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, carburizing, normalizing and quenching.

Normalizing Heat Treatment, Basic Steel & Metal

Normalizing Heat Treatment Definition . Normalizing Heat Treatment process is heating a steel above the critical temperature, holding for a period of time long enough for transformation to occur, and air cooling. Normalized heat treatment establishes a more uniform carbide size and distribution which facilitates later heat treatment operations

NORMALIZING tpub

NORMALIZING . Normalizing is a type of heat treatment applicable to ferrous metals only. It differs from annealing in that the metal is heated to a higher temperature and then removed from the furnace for air cooling. The purpose of normalizing is to remove the internal stresses induced by heat treating, welding, casting, forging, forming, or

Induction Annealing and normalizing advantages 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.
