The purpose of the process of stainless steel bright annealing

430 stainless steel magnetic bright annealing furnace is mainly used to finished product heat in the atmosphere of the processing of stainless steel. When using the performance requirements are not at the same time, on the microstructure of bright annealing after the requirements are different, the process of bright heat treatment are also different.
Heat treatment process of typical 430 stainless steel suppliers magnetic is a solid solution treatment. In the heating process of the carbide dissolve in austenite, heated to 1050 ~ 1150 ℃, the appropriate holding a short period of time, the carbide all dissolved in austenite, and then rapidly cooled to 350 ℃, obtain supersaturated solid solution is uniform one-way austenite. The heat treatment process is the key to rapid cooling, cooling rate reached 55 ℃ /s, fast through the carbide solid solution after precipitation temperature region (550 ～ 850 ℃). Holding time should be as short as possible, otherwise the coarse grain, effects of surface finish.

The scope of application of iron 1.4016 steel 2R and physical phenomena
Iron 1.4016 steel 2R in the heating process the carbide dissolve into austenite, heated to 1050 to 1150 DEG C, the effect of a short period of time, the carbide all dissolved in austenite, and then rapidly cooled to 350 DEG C, to obtain supersaturated solid solution is uniform one-way austenitic organization. The heat treatment process is the key to rapid cooling, the cooling rate reaches 55 DEG C requirements of /s, iron 1.4016 steel 2R fast through the carbide solid solution after precipitation temperature zone (550 to 850 DEG C). Holding time should be as short as possible, otherwise the coarse grain, surface finish.
