316/316L Dual cert
(OP)
Hi everyone,
First time posting. I am a quality manager for a manufacturing shop, machine shop (cnc/sheet metal).
On to my question. We have been machining 316L bar and have had very little trouble up until recently. Our supplier gave us some 316/316L dual certified material. We had no idea how big of a problem this would cause. We have been experiencing work hardening, burning up tooling etc.
What has been the experience in the industry using the dual cert material in regards to machining. We tried to specifiy only 316L but our supplier is stating that the material meets both certs.
Just looking for some input on how to try and resolve this issue
Thank you and look forward to reading the forums more =)

You issues are not related to the chemistry or the dual certification.

We requested strictly 316L from our supplier in the most recent purchase orders. Our delivery today came with 316/316L. Our investigation now takes a turn to see if this supplier is buying from the same distributor as our previous supplier was. I will also be taking a look at the Sulphur content thanks to Remetaper. The material delivered today contained .027% Sulphur.
Thanks again for all the input and I will update if I have any further questions. =)

A quick comparison of the chips from the "old" stainless steel to the "new' stainless steel should tell the story pretty quickly.
