For the failure of a low-temperature globe valve, through disassembly and material analysis, the cause of the failure was initially determined to be caused by adhesive wear between the disc guide rod and the valve seat. From the three aspects of material detection, stress and adhesive wear, the failure mechanism of stainless steel motion pair was analyzed. Finally, the wear test was carried out for chrome plating and non-chromium plating. Tests showed that when the valve seat is chrome-plated, the surface hardness of the guide portion is increased, which could effectively prevent the adhesive wear failure of the guide rod and the valve seat guide hole.
