Quenching is a step in many heat treatment processes that involves heating the part to the required temperature and immersing it in a quenching medium to quickly cool it. Other heat treatment processes often follow quenching, such as aging, tempering, or annealing to achieve the desired results. By rapidly cooling the metal, you can prevent or encourage the formation of different microstructures within the steel to achieve the properties you need for the intended application.
Types of Quenching Media
A quenching medium is a substance you use to quench metal during heat treating processes.
Metallurgists use several types of quenching media, each delivering different results due to their unique properties.
Cooling rate is one important property that significantly affects the final result. Rapid cooling prevents internal changes from occurring, while slower cooling dramatically alters the metal’s crystalline structure.
The Quenching Process
Quenching happens once your part has reached the required temperature and soaked for an appropriate amount of time. Quench your part by removing it from the heat source and immersing it in the quenching medium, which rapidly cools the metal to room temperature and prepares it for further work.
Quenched steel is typically harder and less ductile than it was prior to being heated, which is why quenching usually precedes other heat treating processes such as tempering, aging, annealing, or normalizing.
ABOUT KEVA
Keva Casting is a professional casting company that focuses on Construction, Machinery, Automobile, Hardware, Pipeline and many other industries.
We provide top quality products with the best service based on our complete production chain including our own mold design, advanced production techniques, and full management of the supply chain. Keva Casting has two factories located in Zhucheng, China's Shandong province.
We use "shell molding", which is a new technique that has been developed in recent years.This new technique has simplified production procedures and reduced air pollution compared with traditional sand casting and investment casting. Shell making and core making are faster to ensure production in enormous quantities. The dimensions and surface finishing are satisfactory for all kinds of industrial requirements. Besides supplying our own formwork & scaffolding systems, our casting products also supply OEM services in various industries.
