The process of heating steel to a temperature above its transformation range, followed by air cooling. The purpose of normalizing may be to refine grain structure prior to hardening the steel, to harden the steel slightly, or to reduce segregation.
Normalizing is a process for making material softer but does not produce the uniform material properties of annealing.. A material can be normalized by heating it to a specific temperature and then letting the material cool to room temperature outside of the oven. This process is less expensive than annealing.. See also annealing, stress relieving, tempering.
heating steels to approximately 100 F above the critical temperature range followed by cooling to below that range in still air at ordinary temperatures. This heat treat operation is used to erase previous heat treating results in carbon steels to .40% carbon, low alloy steels, and to produce a uniform grain structure in forged and cold worked steel parts.
A process in which a ferrous alloy is heated to a suitable temperature above the transformation range and is subse?quently cooled in still air at room temperature.
A treatment consisting of heating uniformly to temperature at least 100°F above the critical range (A3) and cooling in still air at room temperature. The treatment produces a recrystallization and refinement of the grain structure and gives uniformity in hardness and structure to the product.
Heating to about 100°F. above the critical temperature and cooling to room temperature in still air. rovision is often made in normalizing for controlled cooling at a slower rate, but when the cooling is prolonged the term used is annealing.
The process used to relieve stresses in steel. The material is heated to about 100 degrees above its critical temperature and allowed to cool in air. This creates an even grain pattern and a malleable steel.
A process of relieving stresses and eliminating hard spots in ferrous metals. Similar to annealing but employing a faster quench, or cooling cycle, to produce a more uniform grain structure and to remove hard spots without excessive softening.
Commonly used heat treatment that decreases pearlite interlamellar spacing and refines grain size. The process consists of heating steels above the transformation temperature range, holding at temperature, and then cooling in air.
Steel heat treatment performed to refine grain size and to alleviate stress in the interior by heating the steel to temperatures ranging from approximately 800°C to 900°C (1472°-1652° F) and air cooling the steel.
A heat treatment for carbon and alloy steel which involves heating above the upper critical transformation temperature (to approximately 1650 F, 900C), holding at temperature about one hour and cooling to room temperature in still air. This process homogenizes the steel by reducing carbon segregation and refining the ferrite and pearlite micro-constituents of steel. It also reduces the stress differential created when lighter sections of a forged part cool faster than heavier sections, and improves machineability.
A common heat treatment that can be applied to metals. Similar to annealing, but does not appreciably soften the metal. Typically done to relieve internal stresses caused by cold working. Back to the Top
A heat treatment process that has the object of relieving internal stresses, refining the grain size and improving the mechanical properties. The steel is heated to 800-900oC according to analysis, held at temperature to allow a full soak and cooled in still air.
The heating of steel to a temperature exceeding its upper critical temperature, followed by cooling freely in still air so that moderately rapid cooling occurs and a fine-grained structure is obtained.
Heat treatment at a temperature above the transformation range creates a phase change in the metal's microstructure. The benefit of vacuum normalizing is the refinement of grains.
heating steels to approximately 100 degrees Farenheit above the critical temperature range followed by cooling to below that range in still air at ordinary temperature. Chemical symbol for Oxygen
Heating a ferrous alloy to a suitable temperature above the transformation temperature Ac3, followed by cooling at a suitable rate, usually in still air to a temperature substantially below the transformation range.
Heating metal to a specified temperature and then cooling to change the properties of the material.
A process of heating the steel above the critical temperature and cooling it freely in air. It is a special case of annealing. Normalizing does leave the metal in a uniform, unstressed condition but may not -leave it machinable. See annealing.
