The impact toughness of quenched steel after tempering at 250-400°C is lower than that obtained on tempering at temperatures below 250°C.If brittle steel tempered at 250-400°C is heated above 400°C and transferred into a tough state,a second tempering at 250-400°C cannot return it to the brittle state. results for this questionWhat is temper embrittlement in steel?What is temper embrittlement in steel?Many alloy steels have two temperature intervals of temper embrittlement.For instance,irreversible temper brittleness may appear within the interval of 250-400°C and reversible temper brittleness,within 450-650°C.Temper embrittlement is inherent in many steels and can be characterized by reduced impact toughness.Temper Embrittlement : Total Materia Article results for this questionWhat is the classification of tempering?What is the classification of tempering?Classification Of Tempering Process Hardened steel parts requiring tempering are heated in the temperature range of 200-350°C.This process gives troosite structure.Troosite structure is another constituent of steel obtained by quenching tempering martensite.Tempering Heat Treatment Process- Classification Of Tempering
