Thank you Jack. We are not worried about magnetism here at this point. We are just trying to understand why it is cracking axially and radially on our shot peened areas. Shot peening might be the cause but we are not sure.
I will make sure we use SS shot in the future.
Walter, as you said, these parts are for oil drilling industry. What do do you think about the following requirements:
* S-110 SS shots at 8-10 "A" intensity, 200% coverage
* S-100 Glass beads at 8-10 "N" intensity, 200% coverage
Thanks in advance,
Muriel
