Introduction To Crack Prevention Technology For Stainless Steel Reducers
The production of Stainless Steel Concentric Reducer is mainly based on pressing, but the pressing process will increase the hardness and density of the steel. However, if it is not heated, it will easily crack.
Control of the diameter range. Generally speaking, the stainless steel reducers are within the processing range at one time. For example, the reducers of 325-159 basically need to be heated several times. First, press the 325 tube to one end and press the 325 aperture into 273. This pressing also needs to be heated. The second diameter change is the process of changing the diameter from 273 to 219. This time, the tube needs to be heated to the specified temperature and then pressed. Then it is the process of changing the diameter from 219 to 159. Each diameter change needs to be heat treated.
Various materials have their own characteristics such as hardness and tensile strength, so the pressing strength of each material is also different. For the same model of stainless steel reducers, the processing methods and procedures will vary greatly depending on the material. For example, ordinary carbon steel reducers will be formed after three heat treatments. However, for alloy reducers, the greater the hardness, the more times of pressing and heating, and the more complicated the forming process.
