Stainless steel pipes must undergo the surface quenching process during the production process. This process can directly cause the quality of the final stainless steel forming. For 316 stainless steel pipes, the product quality requirements are higher, so there are corresponding requirements for the level of processing technology. The editor will introduce the relevant knowledge of surface quenching of 316 stainless steel pipes:

    In general, the surface quenching time includes two stages: heating and heat preservation. The heating stage is when the entire section of the 316 stainless steel pipe is heated to the predetermined surface quenching temperature. The heat preservation stage is the composition in which the carbides are completely dissolved, and the heat preservation stage is the composition of the 316 stainless steel pipe. The temperature structure changes to homogenize austenite.

   Insulation is collectively referred to as the heating time of the general surface quenching temperature, but the 316 stainless steel pipe that charges too high or large, due to the following surface quenching temperature, including the phase change and recrystallization time during heating, so it is heated and held separately.
