How tight can I bend A36 3/4" Plate?
(OP)
I'm looking to bend A36 3/4" plate and I want to find out how tight I can bend it without having any problems. Ideally I'd like to bend it so the inside radius is about 1.125".
Is there a rule of thumb when it comes to how tight bends can be on plates like this?

This was from google & are basic principals.
" Bends
· Bends should be toleranced plus or minus one-half degree at a location adjacent to the bends.
· For the ease of manufacturing, multiple bends on the same plane should occur in the same direction.
· Avoid large sheet metal parts with small bent flanges.
· In low carbon steel sheet metal, the minimum radius of a bend should be one-half the material thickness or 0.80 mm (0.03 inch), whichever is larger.
Flanges
· The minimum height of a bent flange is directly related to the material thickness, bend radius, and length of bend.
· The minimum width of a bend relief is one material thickness or 1.50 mm (0.06 inch), whichever is greater. "
Your at 1-1/2 x thickness of the gauge. which should be good. Material is at 20% elongation so that is good too.
Hardness is soft 68 HRb that is also good.
Material bends best when annealed.
find a vendor with the capacity to bend that large of gauge, & obtain their concurence.
