.622 1018 material breaking
(OP)
I'm currently investigating root cause for problem with material cracking. It's Ø .622-1018 material with a ksi of 85000-105000. The cracks are happening in the inside (compression) of the bend. The wire is ran through a cnc bender and is bent around a .625 roller. We are seeing about a 3-6% crack rate.
KSI/machine speed/roller pressure/etc doesn't seem to be a factor.
We have ran DOE's through our bender and are currently looking at our material suppler for assistance. All material is with astm a510 standards.
Basically I'm looking for ideas/directions to investigate.
Thanks in advance..

I need to find root cause. We have looked at chrome and nickel as being culprits, but cannot get material with these variables far enough on both sides of the spectrum to run tests.
Thanks for the replies.. I appreciate the help.
