Bend radius for steel rod
Bend radius for steel rod
(OP)
I want to create a 90 degree bend in steel rod (1/2"). How do I determine a reasonable bend radius, meaning doable by most fab/machine shops and not destroying the rod?
I'm guessing the answer is ~ 1/2" - 1" but that's a guess.
Thank you!

Depending on steel grade 1/2" would be a minimum but I would make it as large as possible for your application.

A general rule of thumb for most materials is to make the radius on bends of round tube/pipe/rod at least 1.5x the OD.
The smaller you make your radius, the more pressure put on the piece during forming, and the more pressure required for the grip to hold the piece in place (which could give the appearance of a slight bubble on the inside). Not likely for 1/2" steel rod, but possible.
