What is the condition of the steel after quenching?

The condition of the steel after quenching is therefore also referred to as glass-hard. The martensite microstructure formed after quenching is characterized by a very high hardness, but is much too brittle for most applications! In order to give the quenched steel the toughness required for use, the microstructure must be treated again afterwards.See all results for this questionsp.info What is the minimum temperature for tempering steel?Generally, steel should be prevented from tempering between 230 – 280 degrees and stainless steel between 400 – 450 degrees, because a tempering brittleness occurs at this time. After quenching, high temperature tempering is called quenching and tempering.See all results for this questionsp.info 40Cr Alloy Structure Steel-GB/T 3077-China Steel material40Cr Alloy Structure Steel-GB/T 3077-China Steel material. ...

Quenching and tempering of steel - tec-science

The heat treatments explained in the chapter on annealing processesmainly related to the improvement of production-orientated properties such as formability, machinability, etc. In many cases, however, a high degree of hardness or strength is required. This can be seen, for example, in a file blade for processing workpieces. To ensure that the file removes the material from the workpiece and …See more on tec-science.comsp.info 12 Heat Treatment Processes: Annealing, Normalizing ...05 Quenching and tempering.
