What Is Annealing (7 Types of Annealing Process) |

What is annealing? The process of heating a metal or alloy to an appropriate temperature for a certain period of time and then slowly cooling (generally with the furnace cooling) is called annealing.. The essence of annealing is the transformation of the pearlite after heating the steel to austenitizing.What Is Annealing (7 Types of Annealing Process) | What is annealing?

Carburizing times for the same case depth are shorter. There are fundamental differences between the two processes. Nitriding is most commonly carried out on prehardened alloy steels like 4140, 4340 or Nitralloy 135M.
