Six heat treatment questions
What is annealing of steel? What are the types and uses of annealing? Answer: Annealing of steel: Annealing is a heat treatment process that heats steel to a temperature above or below the critical point AC1, and then slowly cools it with the furnace after holding it for a certain period of time to obtain a nearly equilibrium structure. Annealing types: According to the heating temperature, it can be divided into annealing above or below the critical temperature AC1. The former includes complete annealing, incomplete annealing, spheroidizing annealing, and homogenizing annealing, and the latter includes recrystallization annealing and stress relief […]
