That’s really interesting Ed, I hadn’t really considered the effect of strain induced martensitic transformation.
I’m still wondering what my best option is to prevent future failures, especially as this is a pretty common grade for bolting and I haven’t come across any others having a similar...
Hi Ed,
Thanks for your reply.
A4-80 is an austenitic stainless steel with the same chemistry as 316. Class 80 is UTS if 800MPa min and PS of 600MPa. My initial thought was to start with stronger material but in some cases even material which started at over 1000MPa has failed after...
Hi I’m wondering if someone might be able to point me in the right direction with an problem I am seeing.
Recently I have been seeing a lot of failures of A4-80 SS following machining. There is a consistently large drop in strength from the starting properties. Sometimes this is as much as...
