We don't bend much flatbar length ways, but I would assume I'll see the same cracking. I neglected to mention that it's a36 plate, not flat bar. We have down draft burn tables not water. The cracks are usually on the ends of the bend. Typically, 1" or 1-1/2" long. (visible). We have to...
Thanks all. Here's some more info. As a standard practice we match the tool to the steel. Unless specified by our engineers. IE, if we are bending 1/4", we use a punch with a 1/4" radius and a die with a 2" opening. We use A36 structural for about everything. The engineering dept...
We've had some problems when bending a part with the grain. They tend to crack quite badly, and we know that when we bend 90 degrees to the grain it won't crack. The question is, "is 90 degrees to the grain the best, or is 45 best"

I've heard that bending a36 hot rolled at 90 degrees to the bend line is the strongest way to do it. I've also heard that 45 degrees is the best ?
