4 methods of metal heat treatment process
According to the characteristics of metal heat treatment process, we should pay attention to the following points:
Introduction of Two Processes of Heat Treatment in Gear Machining
In the process of gear processing and production, the general manufacturer will arrange heat treatment process. As we all know, the heat treatment process is mainly to improve the hardness and wear resistance of the tooth surface.
Quenching, tempering, normalizing, annealing, silly and unclear?
The quenching of steel is to heat the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), keep it warm for a period of time to make it fully or partially austenitized, and then cool it with a cooling rate greater than the critical cooling rate.
What are the types of heat treatment quenching process?
The types of quenching are divided according to the different cooling forms, mainly including single-liquid quenching, double-liquid quenching, graded quenching and isothermal quenching.
How much do you know about the basic knowledge of metal surface heat treatment process?
Surface heat treatment is a metal heat treatment process that only heats the surface of the workpiece to change its mechanical properties.
