The top three benefits of induction hardening are: - fast heating cycles - accurate heating patterns - cores that remain relatively cold and stable But before you invest in an induction solution for induction hardening, it's important to understand how the process works. Here's part one of our beginner's FAQ about induction hardening. ## What is induction hardening used for? Induction hardening is a heat treatment method that involves the heating of a metal part using induction and quenching. The quenched metal goes through a process called a martensitic transformation, which increases both the hardness and brittleness of the metal part.  ## What is 'quenching?' When used in the context of induction hardening and heat treating processes, quenching refers to the rapid cooling of a metal piece or workpiece in either water, air, or oil in order to bring about specific qualities. Quenching prevents phase transformations and other undesired low-temperature processes from occurring by minimizing the time span in which these processes are kinetically available and thermodynamically ideal. ## What are the most common induction hardening applications? The process of induction hardening is most commonly used in steel alloys. This ie because there are many mechanical parts, including gears, shafts, and springs, that are subjected to surface treatments prior to delivery in order to enhance what is known as wear behavior. However, it's important to keep in mind that the level of effectiveness of any given induction hardening treatment depends on a variety of factors, including the modification of surface material properties and the introduction of residual stress. But above all, the process is known to be one of the most effective and widely employed processes meant to increase component durability. The principles of induction heating have been applied to manufacturing since the 1920s. Understanding the facts about [induction heating equipment](//www.ambrell.com/ambrell-induction-heating) and applications such as induction hardening is the key to determining which heat treatment methods are right for your needs.
