Super long life fatigue behaviors of Q345 bridge steel
Development of Low Cost Q345 High Strength Heavy Steel Plate
Analysis on the Reason for Tensile Fracture Stratification of Q345 Plate
Experimental Research of High Temperature Strength of Low-alloyed Structural Steel Q345;
AMENDING THE POLARIZATION CURVES OF THE Q345 IN NaHCO_3 SOLUTION THROUGH THE METHOD OF EQUIDISTANCE VOLTAGE
Roof purline is adopted with cold-bending and thin-wall steel (Q345), knee bracing, roof horizontal bracing and purline drawn rod Q235.
With electron microscope the fracture surface and metallographic structure analysis is done for typical sample of Q235, Q345 plate of low elongation, its reason found out, some Suggestions proposed.
The cold-bended crack in the hot rolled plate Q345 can be eliminated by adoption of heating-cold bending process as well as improvement of the cleanliness of the steel.
