Stage 1 includes hardening, in which the plate is austenitized to approximately 900°C and then quickly cooled. Argentina Congo, Democratic Republic of the Saint Helena Moreover, it appears that, at least in Europe, 'quenching and tempering separately do not seem to have become common until the 15th century'; it is therefore helpful to distinguish between 'full quenching' of steel, where the quenching is so rapid that only martensite forms, and 'slack quenching', where the quenching is slower or interrupted, which also allows pearlite to form and results in a less brittle product. Your message has been sent and will be treated as soon as possible. Albania This also allows you to obtain a bainite or martensite structure.
