In addition to excellent corrosion resistance, 316 stainless steel forgings also have high strength, high hardness, high wear resistance, wide operating temperature range (up to 500~550 °C, as low as -253 °C) and good process plasticity. Etc. 316 stainless steel forgings contain a large amount of alloying elements such as nickel and chrome. The processing in the forging factory can significantly change the microstructure of the 316 stainless steel forgings. Due to different organization and different performance, different measures should be taken in forging production and treated separately. Therefore, due to the high price of stainless steel materials, the following points should be noted when forging 316 stainless steel forgings in forgings:

1. When the forging factory forges 316 stainless steel ingots, it starts to lightly press, and when the deformation reaches 30%, it can be pressed. When forging, it should be fed in one direction to avoid repeated pressing at one place to prevent center cross cracks.

2. The forging ratio of forgings is 4~6, and the billet is 2~4, depending on the grain size of the raw materials. The grain size of 316 stainless steel forgings has a great influence on the corrosion resistance of steel. In order to obtain fine grains and fully weld the micro-cracks and pores in the central region, it should be ensured that the latter fire has a sufficiently large forging ratio, and the deformation amount should be greater than the critical degree of recrystallization, and the deformation should generally be greater than 12% to 20%.

3. In the deformation process of the 316 stainless steel forging blank, uniform deformation is required to obtain a relatively uniform grain structure.

 4. Due to the large shrinkage rate of 316 stainless steel. When the forging is finally formed, a large shrinkage ratio (1.5 to 1.7%) should be considered to prevent the forging from being scrapped due to insufficient size after cooling.

5, 316 stainless steel forgings temperature should be cut above 850 ° C (cold forgings should be preheated to 900 ~ 950 ° C and then cut edge).
