Tempering is a crucial process in metalworking that enhances the properties of metals, such as hardness, toughness, and ductility. There are three main types of tempering, each designed to achieve specific results. Let's explore these methods in detail.
What are the Three Types of Tempering? (3 Key Methods Explained)
1. Quench & Temper
Quench & Temper is specifically used for hardening medium carbon alloy steel.
This process involves heating the steel parts above their transformation range.
Then, the parts are rapidly cooled, typically using an oil quench.
After quenching, the parts are reheated to a lower temperature to temper them to the desired final hardness range.
This process increases both the strength and hardness of the steel.
2. Hardening & Tempering
Hardening & Tempering is a through-hardening process that hardens the metal part from surface to core without altering the surface carbon content.
The metal is heated above its austenitizing temperature in an enclosed furnace.
Then, it is quenched.
After quenching, the metal is tempered by reheating to a lower temperature.
This improves its toughness and ductility while maintaining hardness.
3. Selective Heat Treating (including Case Hardening, Induction Hardening, and Flame Hardening)
Selective Heat Treating involves methods of selectively hardening specific areas of a metal part.
These methods include localized heating and quenching processes.
Case Hardening adds carbon to the surface layer before quenching and tempering.
Induction Hardening and Flame Hardening use rapid heating and quenching in specific areas to harden them.
These methods allow for targeted improvements in hardness and wear resistance in specific areas of the metal part.
