Bending Round Bar 1

[Derricksl]

Can anyone advise what bend radius should be used for 16mm diameter round bar?

Are there any issues with cracking / materials that need to be considered?

Thanks

I believe this will depend upon the material properties of the bar. For instance, for higher strength material you need a larger bend radius to prevent cracking.

Heating either prebend or post stress will allow tighter radius bends.

Dont know if this is of any help but the British Standard gives minimum bending radius of 2D for mild steel and 3D for high yield for 6-20 mm rebar

Thanks to all for the quick response.

Are the 2D and 3D figures for hot or cold bending?
