| Note: Rom is the measured tensile strength of steel bars; RoeL is the measured yield strength of steel bars. | |||||||
Bending properties:
HRB500 carbon steel rebar should be subjected to bending test.After the diameter of the bending indenter is bent by 180°, the surface of the HRB500 rebar subject to bending must not produce cracks.
