Q345 angle steel price

To study Q345 angle steel fatigue behavior in alternating wet and dry atmoSPHEric corrosion and wind-induced fatigue xoupling reaction, we have taken the " corrosion - fatigue" alternate wetting and drying cycle cyclic loading on the Q345 angle member expand corrosion fatigue performance measurement test.
As we all know, Q345 Angle steels have been vastly applied to high-voltage transmission line tower structures. And  the tower connecting portion was gradually damaged due to the long atmospheric corrosion and vibration, as a result, Q345 angle steel in the tower become the most weak link to the whole tower.
Conclusion With increasing times of “Immersion-drying” alternating cycles, the Q345 angle steel damage increased, and the fatigue life of specimens decreased, showing that the corrosion fatigue life of specimens was obviously affected by the atmospheric environmental dry-wet alternate corrosion. In the same type of corrosion, the smaller the fatigue load, the more significant the influence of corrosion, and the more obvious the brittle failure characteristics.
