Suzhou jinruier Electric Furnace Co., Ltd. (annealing furnace manufacturer) shares stainless steel solution treatment process with you.
According to the different materials of stainless steel, the process of solid solution treatment of stainless steel is very different. The solid solution treatment of 300 series austenitic stainless steel softens it. During the heating process, the carbides are dissolved into austenite, heated to 1050-1150 ℃ for a period of time, so that the carbides and various alloy elements are evenly dissolved in austenite, and then rapidly quenched and cooled to below 350 ℃, so that the carbon and other alloy elements can not precipitate in time, and the supersaturated solid solution, namely uniform unidirectional austenite structure, is obtained. The key of this heat treatment technology is rapid cooling, the cooling rate needs to reach 55 ℃ / s, and the re precipitation temperature zone (550-850 ℃) after rapid carbide solution. The holding time should be as short as possible, otherwise the grain size will be coarse and the surface finish will be affected.
For stainless steel, the three elements of solution treatment are temperature, holding time and cooling rate. According to the characteristics of stainless steel solution, our company developed a roller type continuous solution furnace for stainless steel pipe. The stainless steel tube moves forward continuously through the continuous rotation of the idler, so that the heating is uniform, the holding time is controllable, and the rapid cooling can be achieved after the holding. In this way, the hardness of the stainless steel tube after solution treatment is uniform and the quality is obviously improved.
