Tempering is most often performed on steel that has been heated above its upper critical A 3 temperature and then quickly cooled, in a process called quenching , using methods such as immersing the hot steel in water, oil, or forced-air.
The quenched-steel, being placed in or very near its hardest possible state, is then tempered to incrementally decrease the hardness to a point more suitable for the desired application. The hardness of the quenched-steel depends on both cooling speed and on the composition of the alloy. Steel with a high carbon-content will reach a much harder state than steel with a low carbon-content. Likewise, tempering high-carbon steel to a certain temperature will produce steel that is considerably harder than low-carbon steel that is tempered at the same temperature.
The amount of time held at the tempering temperature also has an effect. Tempering at a slightly elevated temperature for a shorter time may produce the same effect as tempering at a lower temperature for a longer time. Tempering times vary, depending on the carbon content, size, and desired application of the steel, but typically range from a few minutes to a few hours.
Except in the case of blacksmithing, this range is usually avoided. Instead, a variation in hardness is usually produced by varying only the tempering time. When heating above this temperature, the steel will usually not be held for any amount of time, and quickly cooled to avoid temper embrittlement. Steel that has been heated above its upper critical temperature and then cooled in standing air is called normalized steel.
Normalized steel consists of pearlite , martensite and sometimes bainite grains, mixed together within the microstructure.
This produces steel that is much stronger than full-annealed steel, and much tougher than tempered quenched-steel. However, added toughness is sometimes needed at a reduction in strength. Tempering provides a way to carefully decrease the hardness of the steel, thereby increasing the toughness to a more desirable point. Cast-steel is often normalized rather than annealed, to decrease the amount of distortion that can occur. Tempering can further decrease the hardness, increasing the ductility to a point more like annealed steel.
The process, called "normalize and temper", is used frequently on steels such as carbon steel, or most other steels containing 0. These steels are usually tempered after normalizing, to increase the toughness and relieve internal stresses. This can make the metal more suitable for its intended use and easier to machine. Steel that has been arc welded , gas welded , or welded in any other manner besides forge welded , is affected in a localized area by the heat from the welding process.
This localized area, called the heat-affected zone HAZ , consists of steel that varies considerably in hardness, from normalized steel to steel nearly as hard as quenched steel near the edge of this heat-affected zone. Thermal contraction from the uneven heating, solidification and cooling creates internal stresses in the metal, both within and surrounding the weld.
Tempering is sometimes used in place of stress relieving even heating and cooling of the entire object to just below the A 1 temperature to both reduce the internal stresses and to decrease the brittleness around the weld. Localized tempering is often used on welds when the construction is too large, intricate, or otherwise too inconvenient to heat the entire object evenly.
After the bar exits the final rolling pass, where the final shape of the bar is applied, the bar is then sprayed with water which quenches the outer surface of the bar.
The bar speed and the amount of water are carefully controlled in order to leave the core of the bar unquenched. The hot core then tempers the already quenched outer part, leaving a bar with high strength but with a certain degree of ductility too. Tempering was originally a process used and developed by blacksmiths forgers of iron. The process was most likely developed by the Hittites of Anatolia modern-day Turkey , in the twelfth or eleventh century BC.
Without knowledge of metallurgy, tempering was originally devised through a trial-and-error method. Because few methods of precisely measuring temperature existed until modern times, temperature was usually judged by watching the tempering colors of the metal.
Tempering often consisted of heating above a charcoal or coal forge , or by fire, so holding the work at exactly the right temperature for the correct amount of time was usually not possible. Tempering was usually performed by slowly, evenly overheating the metal, as judged by the color, and then immediately cooling, either in open air or by immersing in water.
This produced much the same effect as heating at the proper temperature for the right amount of time, and avoided embrittlement by tempering within a short time period.
However, although tempering-color guides exist, this method of tempering usually requires a good amount of practice to perfect, because the final outcome depends on many factors, including the composition of the steel, the speed at which it was heated, the type of heat source oxidizing or carburizing , the cooling rate, oil films or impurities on the surface, and many other circumstances which vary from smith to smith or even from job to job.
The thickness of the steel also plays a role. With thicker items, it becomes easier to heat only the surface to the right temperature, before the heat can penetrate through. However, very thick items may not be able to harden all the way through during quenching. If steel has been freshly ground, sanded, or polished, it will form an oxide layer on its surface when heated.
