I have a plate with a crack [looks to me]I was wondering if it could be used as is
Thank you Larry
That looks like a casting flaw, not a true crack.
How does the other side look? Does it go all the way through?
I agree with Jack. Would be an odd place for a crack to start and end in the middle of an object. If it started at a rivet hole, then that would make more sense.
I would at least check it with a dye penetrant. A crack like that can extend well past what is readily visible. Dave
Norman Can t see other side Its between rivets
If it runs to the rivet holes it may not spread as the rivet holes are effectively drilling the crack ends.
I wonder if that is in fact a "forging blister" that often appears on the surface of some of the larger forged parts. These are really not a crack but more of a crevice in the surface that is caused by the metal being folded back upon itself during the forging process. If you then cut the surface via machining over one of those spots you will get a "crack" like the thing in your picture. Ford seemed to not be concerned about them since you will find them on many of their larger forged parts if you look close. They never appear to be a crack all the way through the metal like a typical stress crack.
Not a problem.
