Standard Bend Radii For Steels

[rdpostak]

I have always used as a rule of thumb for bending 2 x material thickness. Is that the norm?

This is yet another "larger than life" questions.

Typically 1x for thinner mild steel, 1.5x for anything above 12ga, 2x for hard steel or other metals.

Also depends heavily on available tooling. I like to check what bending tools are on hand and stick with those. Especially important if making difficult bends that may require specialized tooling (e.g. gooseneck).

Why use rules of thumb when you can use an authoritative source for a mere $10.
