Improper heat treatment of non-standard parts can have a significant impact on their important processes, manifested in the following aspects: 1. Product quality: Heat treatment is a key process to improve material properties, and improper heat treatment may lead to surface cracks, pores, deformation, and other defects, thereby reducing product quality and appearance. In addition, the hardness, strength, toughness and other properties of the material may not meet the design requirements due to improper heat treatment, which affects the safety performance of the product. Processing accuracy: The shape, size, and other aspects of non-standard parts are different from standard parts, and the processing process requires higher accuracy and more debugging. Improper heat treatment may lead to uneven stress distribution inside the material, making it easy for the parts to deform during processing and affecting machining accuracy Service life: Improper heat treatment can reduce the fatigue strength and wear resistance of parts, making them susceptible to wear and damage during operation. This may lead to premature failure of the parts and reduce their service life Safety: If non-standard parts are used in critical areas such as car engines, airplane wings, etc., improper heat treatment may cause the parts to fracture or fail under extreme conditions, leading to safety accidents. In order to avoid problems caused by improper heat treatment of non-standard parts, the following measures should be taken: 1. Strictly implement the heat treatment process requirements, control key parameters such as heating temperature, insulation time, cooling rate, etc Choose a reputable heat treatment manufacturer to ensure the quality of heat treatment Strengthen testing and inspection to ensure that the hardness, strength, toughness, and other performance indicators of the parts meet the requirements For complex or critical non-standard parts, detailed heat treatment process analysis and experimental verification should be conducted to ensure that the treatment effect meets the requirements.
