Ex-Ten Fabricating Practice For Cold Forming
| Thickness | Suggest Min. Inside Radius for Angle Bends |
|---|---|
| Up to .187 Incl. | 1 1/2t |
| Over .187 to .2299 (Sheets Only) | 2t |
| Plates (1/2” Max) | 2 1/2t |
Hot forming is recommended for plates over ½” thick. Hot forming may result in the lowering of the as-rolled mechanical properties.
