Analysis of Deformation Factors and Control Strategies in Stainless Steel Elbow Production: A Technical Discussion on Promoting the Quality Improvement of Pipe Fittings Manufacturing Stainless steel elbows, as key connecting components in pipeline systems, directly affect the safety and reliability of the entire system with their quality. During the production process, deformation of elbows is a core issue that influences product quality. This article will comprehensively analyze the deformation factors of stainless steel elbows in the production process, including material properties, processing methods, mold design, and temperature control, and propose effective control strategies to provide technical references for improving the manufacturing quality of stainless steel elbows. I. Material Properties and Deformation Mechanism The deformation problem in the production of stainless steel elbows is closely related to the material's own properties. Stainless steel has a high elastic modulus and Poisson's ratio, making it prone to deformation under external forces. At the same time, its excellent plasticity and toughness also make it easy to be stretched and bent, which is the theoretical basis for cold forming.
