NADCAP Certified - Heat Treat Continuous Belt Driven Oven question

Is there anyone that works for a spring manufacturer that is NADCAP certified for the Heat Treat process? I have questions regarding our continuous belt driven ovens. Any help would be greatly appreciated.

My question is this: Is Stress Relieving of stainless steel wire considered a Heat Treat Process? Does it fall under the NADCAP rules or does NADCAP strictly consider when you change the properties of the material such as when you use 17-7 CRES wire and need to make it meet CH900 specification?

Hi Paccnc,

With people that are busy and maybe not able to check the forums daily, you may want to post your questions here so that they can be more easily answered. If you attempt to establish contact (and there is nothing wrong with that) before you ask your questions, you may end up spending days before you get your question(s) answered.

For example, someone sees your post tomorrow and responds "I can try to help, what are your questions." You log in late tomorrow or the following day and post your questions. The person that said they can help may get busy on Thursday or Friday and they don't check back till next week. Had the questions been posted they could have responded the first time they saw your post.

Just a suggestion to post them now to expedite you receiving an answer. :)

Heat treat covers stress relief when your required by the prime (ie Roll Royce, Boeing, AirBus ect) or when a supplier wants to go through the Nadacp approval process and there are no other jobs audits available. Nadcap quidance is to not use stress relief unless there is no other job audit available.
Stress Relief realy falls into that grey area depending on the engineering group involved.
