Metal Supermarkets - Steel, Aluminum May 09, 2019 · Quench Hardening Steel Steel deserves a special mention when the quenching process is being discussed because its mechanical properties are very sensitive to quenching. Through a quenching process known as quench hardening , steel is raised to a temperature above its recrystallization temperature and rapidly cooled via the quenching process.

What is Quenching? Why Steel Needs to be Quenched?

The purpose of quenching is to transform the undercooled austenite into martensite or bainite to obtain martensite or bainite structure; quenching associated with tempering at different temperatures can significantly improve the steel rigidity, hardness, wear resistance, fatigue strength, toughness etc., enabling the steel to meet various requirements of different mechanical parts and tools. What is quenched and tempered steel? - ShapeCUTBy tempering quenched steel, it becomes less brittle and more ductile without sacrificing too much hardness. It is the combination of these two processes that produces a harder, tougher steel thats more weldable and ductile than ordinary carbon steel. While it takes longer to manufacturer, the increased strength makes up for the delay.
