...). The austenitization temperatures vary with the carbon composition of the steel and are shown in approximations in Fig. 4.23 . Austenitization is discussed in more detail in Chapter 11 . Quenching: The hot steel is rapidly cooled by immersion in water or oil. Quenching techniques are discussed further...

.... Figures 16.8 and 16.9 show the results of oil quenching on the hardness distribution in round bars of various diameters for the SAE 1045 and 6140 steels, respectively. Oil is a much less severe quenching medium than water, and so the cooling rates of oil-quenched bars are appreciably lower than those...

For example, one study compared the distortion obtained with quenching of a 0.4% medium-carbon plain steel bar of 200 mm diameter by 500 mm long in water or oil from 680 °C ( Ref 15 , 16 ). The results, shown in Fig. 16(a and c) , show essentially equivalent variation in diameter...

.... Different types of quenchants have different types of cleaning requirements before tempering. Oil quenchants need to be removed before tempering. Quench oils burn in the tempering furnaces, and if they are not removed, the parts in a tempering retort can actually glue together. The oil can coat the parts...
