While some workpieces are left in the oven to cool in a controlled fashion, other materials and alloys are removed from the oven. Once removed from the oven, the workpieces are often quickly cooled off in a process known as quench hardening. Typical methods of quench hardening materials involve media such as air, water, oil, or salt.
41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly, cro-moly, CrMo, CRMO, CR-MOLY, and similar).
Normalizing not only produces pearlite but also martensite and sometimes bainite, which gives harder and stronger steel but with less ductility for the same composition than full annealing. In the normalizing process the steel is heated to about 40 degrees Celsius above its upper critical temperature limit, held at this temperature for some ...
TPRC Tin is well annealed 99.999+% pure white tin with residual electrical resistivity ρ 0 =0.000120, 0.0001272 & 0.000133 μΩ cm respectively for the single crystal along directions perpendicular and parallel to the c axis and for polycrystalline tin P. The recommended values are thought to be accurate to within 3% near room temperature and ...
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. [8]

Just cook them in an oil rich in unsaturated fats, like safflower, grapeseed or olive oil, instead of butter, says Rose-Francis. Related: ...
Normalized steel has a higher strength than annealed steel; it has a relatively high strength and hardness. [18] Quenching Carbon steel with at least 0.4 wt% C is heated to normalizing temperatures and then rapidly cooled (quenched) in water, brine, or oil to the critical temperature.
