WebbTempering and annealing are both heat treatment processes that alter the physical and chemical properties of metals to prepare them for manufacturing. The difference between the two processes relate to the temperatures and cooling rates, with tempering happening at lower temperatures but with faster cooling times.

Webb25 feb. 2024 · This difference in hardness is probably due to “autotempering” which can occur when the steel cools sufficiently slowly. The martensite undergoes some tempering during cooling, whereas we normally think of tempering as being a separate step where the steel is reheated. Critical Cooling Rate Webb12 feb. 2024 · The increasing hardness is attributed to the formation of a finer pearlite and ferrite microstructure that can be obtained during slow cooling under ambient air. In general, the commonly used heat treatment process for the steel include annealing, quenching, tempering, boronizing, carburizing, case hardening, nitriding, decarburizing, …
