In simple terms, heat treatment is the process of heating the metal, holding it at that temperature, and then cooling it back. During the process, the metal part will undergo changes in its mechanical properties. This is because the high temperature alters the microstructure of the metal. And...
Although most people don’t know what heat treatment is, it’s actually an essential part of the manufacturing process. That’s because heat treating allows a metal piece to be improved in order for the material to better withstand wear and tear. Heat treatment involves heating a metal or al...
What is heat treatment in CNC machining? An integral step in CNC machining metal parts, heat treatment is the process of controlled heating and cooling of a material to achieve desired material properties. It alters four of the main material properties of metal parts, which are hardness, strengt...
Exactly What Is Heat Treatment Doing?Heat Treatment Selection & Application of Tool Steels
I found out recently that heat treatment is also a term for a process used on gemstones that can make them look darker and more vibrant. However some people think of it as like creating synthetic gems and prefer the natural colors of the stones, so heat treated stones are often priced low...
Normalizing heat treatment is a process applied to ferrous materials. The objective of the normalizing heat treatment is to enhance the mechanical properties of the material by refining the microstructure. The ferrous metal is heated to the austenite phase, above the transformation range, and is subs...
Heat treating is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment invol...

This article discusses the post weld heat treatment (PWHT) process and its effectiveness in reducing the residual stresses and improving the mechanical properties of weldments. Image Credit: Funtay/Shutterstock.com What is PWHT? Post weld heat treatment (PWHT) refers to any heat treatment performed...
After carbonitriding, it is directly quenched at the carburizing temperature (820-860 ℃), and then tempered at a low temperature of 160-200 ℃× 2～3h。 This process is simple and suitable for medium and low carbon steels and low alloy steels. Satisfactory surface and central structures can...
