Basic principles of steel heat treatment

Ki sa ki tretman an chalè nan asye?

Steel chofe nan yon eta solid pa metòd apwopriye, prezèvasyon chalè, ak refwadi nan tanperati chanm nan yon to refwadisman sèten chanje estrikti nan asye a chanje pèfòmans li yo. Yo rele sa tretman chalè nan asye.

Therefore, the purpose of heat treatment is to change the properties of the workpiece by changing the surface or internal structure of the material to obtain the required mechanical properties. For example, quenching:

① Improve the mechanical properties of metal materials or parts. For example: improve the hardness and wear resistance of tools, bearings, etc., improve the elastic limit of springs, and improve the comprehensive mechanical properties of shaft parts.

② Amelyore pwopriyete materyèl oswa pwopriyete chimik kèk asye espesyal. Tankou amelyore rezistans korozyon nan asye pur ak ogmante mayetis pèmanan nan asye mayetik.
