Precision Honing Process
Following cold drawing, the tubes undergo specialized honing operations that employ advanced scraping and rolling methodologies to refine surface characteristics. This critical finishing stage generates beneficial residual compressive stresses within the material microstructure, effectively sealing micro-scale surface imperfections while simultaneously enhancing corrosion resistance. The synergistic combination of these processes significantly improves fatigue strength by impeding the propagation of fatigue cracks, ultimately yielding a superior product engineered for demanding industrial applications.
