Heat Treatment Normalizing

Define normalizing in heat treatment: heat treatment normalizing is a kind of heat treatment to improve the toughness of steel. In the normalising process, after the steel members are heated to 30-50 ℃ above Ac3 temperature, they shall be kept for a period of time and discharged for air cooling. The main feature is that the cooling rate is faster than annealing but lower than quenching. 

During the normalizing process, the crystalline grains of steel can be refined in a slightly faster cooling process. Not only the satisfactory strength can be obtained, but also the toughness (Akv value) can be significantly improved and the cracking tendency of components can be reduced, meeting the purpose of normalizing. After normalizing, the comprehensive mechanical properties of some low alloy hot rolled steel plates, steel forgings and castings can be greatly improved, and the cutting properties can also be improved. As a process of heat treating, normalizing by WALKSON, a professional heat treatment manufacturer, is widely used for alloy steel casting, carbon steel casting, alloy steel forging products, etc. For more information, please feel free to contact us and get relevant pdf documents.
