Oops on the molecular comment. And the modulus of elasticity remark should have been yield strength. I know that ASTM A36 has a yield strength of 36,000 psi and an allowable bending stress of 22,000 psi. That makes calculations easier. Those properties allow steel to deform steadily as...
By no means am I asking for calculations. I seek input on experiences, and simply want info about what happens to steel strength molecularly at a 90-degree bend once it exceeds its modulus of elasticity. Can such steel resist relatively minor forces? If my question rubs anyone the wrong way...
I want to make a 90-degree cold bend in a .25” x 3.5” x 17” long 1018 Cold Finish Mild Steel rectangular bar -- 4” from one end. The 13” leg would sit flat and the 4” leg would be vertical. (I could alternately use .25” x 4” x 17” Hot Roll A36 Mild Steel.) My inquiry concerns the steel...
