How to solve the various defects that may occur during heat treatment?

How to solve the various defects that may occur during heat treatment? During industrial production, heat treatment is a key process, that can give specific properties and strength to workpieces. However, the heat treatment process is not always smooth sailing. Various defects often occur. These defects are like hidden “landmines”. If not taken seriously and solved, they will seriously affect the performance and service life of the workpiece. Today, let’s take a closer look at the various defects that may occur during heat treatment and how to control them. 1. Overheating and overburning Defect manifestation: Overheating: During the heating process of the workpiece, the austenite grains are significantly coarsened due to too high temperature or too long holding time. This will lead to a reduction in the strength and toughness of the workpiece, especially the impact of toughness. Over-burning: The heating temperature is too high, which not only makes the austenite grains coarse but also causes local oxidation or melting of the grain boundaries. The performance of the over-burned workpiece has seriously deteriorated and cannot be saved, so it can only be scrapped. Control method: Strictly control the heating temperature and holding time, and operate according to the process requirements....
