Forging manufacturers: how to heat treat stainless steel forgings?
Forging manufacturers: stainless steel forgings forging directly after the use of waste heat for heat treatment, forging and heat treatment closely together, saving a lot of energy used for reheating in ordinary heat treatment. For example, after forging stainless steel forgings, the direct use of waste heat quenching, also known as high-temperature deformation heat treatment, so that stainless steel forgings to obtain a good overall mechanical properties.
Forging manufacturers: forging waste heat quenching refers to stainless steel forgings after forging in the quenching medium for rapid cooling, in lieu of the original reheating quenching process. Forging residual heat annealing refers to the forging of stainless steel forgings after forging slow cooling, in lieu of the original reheating annealing.
Forging residual heat normalisation refers to the air cooling of stainless steel forgings after forging, instead of the original reheating normalisation. Forging residual heat isothermal normalizing refers to the stainless steel forgings after forging rapid cooling to isothermal temperature after holding, instead of reheating isothermal normalizing.
Forging manufacturers: stainless steel forgings forged directly into the even heat treatment furnace, still the implementation of stainless steel forgings conventional heat treatment process. Stainless steel forgings are evenly heated to ensure that stainless steel forgings in quenching, normalizing and isothermal normalizing at the same temperature. This method is called afterheat immersion heat treatment. For complex shapes, especially the stainless steel forgings with large cross-sectional changes, the process can ensure stable heat treatment quality of stainless steel forgings.
Forging manufacturers: the use of forging waste heat quenching, forging waste heat even heat quenching, forging waste heat normalizing, forging waste heat isothermal normalizing process, the grain size of stainless steel forgings is greater than the conventional heat treatment process. In order to refine the grain, stainless steel forgings can be cooled to 600 ℃ ~ 650 ℃, and then heated to the temperature required for quenching (normalizing), which can refine the grain and reduce the energy consumption of stainless steel forgings heated from room temperature to 600 ℃ ~ 650 ℃. Generally used for stainless steel forgings with high grain size requirements.
Forging manufacturers: on the basis of reliable quality of raw materials, one of the tasks of forging is to obtain the required shape, size and surface condition of stainless steel forgings to meet the requirements of the parts processing and use conditions, and in line with the provisions of the parts drawing.
