The following common quality problems may exist in the production process of stainless steel forgings: Shrinkage loosening: In the forging process, stainless steel forgings may produce shrinkage phenomenon, that is, the material density in the center is low. Shrinkage and loosening may lead to a decline in the mechanical properties of stainless steel forgings, thereby affecting their reliability and safety. Coarse grain: If the forging temperature is too high or the cooling rate is too slow, the problem of coarse grain may occur in stainless steel forgings. Coarse grain will reduce the strength and toughness of the material, which is easy to cause fracture or deformation. Cracks: Cracks may occur in stainless steel forgings during forging, heat treatment or processing due to temperature changes or stress concentration. Cracks have a serious impact on the reliability and safety of stainless steel forgings. Size deviation: The size deviation of stainless steel forgings may be caused by improper process control, equipment wear and other reasons. Too large size deviation may lead to assembly difficulties, function failure and other problems. Surface defects: There may be defects on the surface of stainless steel forgings, such as oxide, burns, inclusions, etc. These surface defects not only affect the appearance quality, but also may lead to corrosion, fracture and other problems. Chemical composition deviation: The chemical composition of stainless steel forgings needs to meet the design requirements and standards, if the chemical composition deviation is too large, it may lead to the corrosion performance, strength and other aspects of the material is not up to standard. In order to solve the above quality problems, it is necessary to strengthen the production process control, reasonable selection of materials and equipment, and comprehensive inspection and testing to ensure that the quality of stainless steel forgings meets the requirements.
