How Quenching Hardens Steel in Metalworking

As a result, quenched steel typically undergoes a tempering process. This involves reheating the metal to a temperature below a critical point, then allowing it to cool in the air. Typically, steel will be subsequently tempered in oil, salt, lead baths, or furnaces with air circulated by fans to restore some of the ductility (ability to quenched and tempered steelsHow to Weld Quenched and Tempered Steels | WELDING A very common quenched and tempered steel is ASTM A514.

What is hardened steel used for? | AnswersDrive

The term hardened steel is often used for a medium or high carbon steel that has been given heat treatment and then quenching followed by tempering. The quenching results in the formation of metastable martensite, the fraction of which is reduced to the desired amount during tempering.What is quenched and tempered steel? - ShapeCUTThe toughness-factor means greater resistance to wear and abrasion. That is why quenched and tempered steel is particularly useful in machinery and structures where greater abrasion resistance and higher yield strength are necessary, such as mining, quarrying, earth moving and construction.What is the Difference between Heat Treatment, Annealing quenched and tempered steelsThis article is about the difference between heat treatment, annealing, and tempering. The article explains the effects of annealing and tempering on the physical properties of metals, such as ductility, strength, and brittleness. Also explained are the methods for annealing and tempering, as well as the microscopic changes that heat treating causes.

difference between normalizing, tempering, annealing and quenched and tempered steels

The material is then often tempered to reduce the brittleness that may increase from the quench hardening process. Items that may be quenched include gears, shafts, and wear blocks. Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy.
