C. Tools made from higher alloy steels are also hardened and tempered but require significantly higher temperatures, up to 1300 deg. C. for hardening and multiple tempering treatments are often required.See all results for this question

Following quenching, the work-piece is in its hardest but most brittle condition and therefore requires a further thermal treatment (tempering, or drawing), to produce the optimum balance of properties. This consists of re-heating the work-piece to a lower temperature and holding for a specific time.See all results for this questionHow is the quenching medium chosen for steel?Selection of the quenching medium is dependent upon steel analysis, component geometry, the heat treatment furnace used and the manufacturing stage at which hardening and tempering is carried out. The resultant temperature changes induce physical transformation of the steel, resulting in mechanical property changes.See all results for this questionHow does the hardening and tempering treatment work?The hardening and tempering treatment consists of heating the work-piece to an appropriate hardening temperature, which is dependant upon the particular steel analysis involved, holding for sufficient time to ensure the whole work-piece is at temperature, and then rapidly quenching it in a suitable medium, cooling the steel.See all results for this question

The quenching medium can be air, oil, water, molten salt, fluidised bed or a pressurised inert gas, such as nitrogen. Selection of the quenching medium is dependent upon steel analysis, component geometry, the heat treatment furnace used and the manufacturing stage at which hardening and tempering Estimated Reading Time: 3 minsGb3077 - SlideShareJun 18, 2015 · Brinell Hardness on anneal or high tempering condition Notes: 1.

Annealing: Annealing is the process of softening a material to obtain desired chemical and physical properties. Hardening: Hardening or quenching is the process of increasing the hardness of a material. Tempering: Tempering is the process of heating a substance to a temperature below its critical range, holding and then cooling.Estimated Reading Time: 6 minsChemical composition, Mechanical 20mnmob quenching and tempering steel Slitting - steel-grades 20mnmob quenching and tempering steel SlittingGBT 20MnMoB Steel Physical Properties. by Longhai special steel - China steel suppliers E-mail: [email protected]steel-grades 20mnmob quenching and tempering steel Slitting www.steel-grades 20mnmob quenching and tempering steel Slitting Chemical composition physical Properties standard download Round bar, Tube/Pipe, Steel plate, Sheet, Coil, Flat bar, Cold rolling, Steel wire, Steel strip.
