| Abstract: | U-type 18-8 bolts in the cooling tower fans in the refinery of Yanshan Petrochemical Company fractured after only 160 hours' service. The testing found nothing wrong in the chemical compositions, metallographic structure and mechanic performance. The analysis concluded that the fracture was caused by the fatigue failure under the alternating loads. The operation became normal after the bolts were replaced with 2Cr13 metallurgy. |
