First, if this is not the right place move the thread, no explanation needed. Now for the meat of the post. When plate needs to be bent are there different grades of steel to use? My "?" comes from looking at a lot of plate and seeing how porous it is. When something in the 1/4" range is bent at a 90* angle does it created stress rises that would lead to possible cracking when put under a heavy load? Is there a certain type/grade that lends itself better to being bent. The intended use is for an 8274 mount.
