Avoiding Rust on 410 Stainless Steel

MM: Just to clarify the 410 SS is not being used as blade material.
If I was designing this product it would be with 304 SS for this application but someone thought better many years ago.
Since I am not in a position to redesign (for now). I would like to avoid going down that road (for now).
I agree with all of the above. Unless you are hardening the 400 series SS, the 300 series would be better. While you are reluctant to bring up the discussion now, perhaps the difficult dissucsion now would lead to a great many headaches later?

By the way, is the product packaged in paper? If so, then is the paper acid free? You would be suprised what an acid treated paper can do to SS or chrome plated steel.

Bill: My point was - this material can be under attack during the trasportation or storage and unless you putting a very light Silicone coating on your product for protection, it is very possible to continue to see the same problem...

One of the smartest decisions I ever made during my tenure running a high tech machining company was to hire an ex-Boeing employee laid off during a Boeing down time. The guy was the most obsessive-compulsive problem solver I ever saw. In a situation like the one described by the OP, he would have personally followed the product from raw material supplier through forming operations, cleaning, passivating, rinsing, drying, storing and noted any anomalies in the process as well as at what point in time the rust began to appear. With that as a starting point, he would have formed some hypotheses about causes and set up experiments to prove or disprove each hypothesis.

Has anyone gone through such a rigorous examination in each step of the process to get an idea where the root cause lies? Without an "eyes on" approach, the rest of us are just speculating based on our past experiences, which may or may not coincide with the true facts of the situation.

Wes, I agree with your insight about a thorough investigation. I think the people answering this forum question have provided great support and their speculation is close to target.

The Forum responses will stand the test of time by being there for others with similar problems. I don't want to waste anyones time and believe the forum has now given all the direction possible. Now it is up to my client on how important this is to resolve.

It is most likely time to close this thread. Can someone assist indoing that?

Threads never really ever close...they live on for the next person who may have a similar problem to tack onto. Or, as new info comes up, it is updated for the sake of people who are searching for similar answers.

Yep! What Bob said. Eventually, a thread goes into limbo until someone doing a search comes upon it and VOILA! resurrection!

Tip - original poster helps put a thread into limbo with a comment saying, in effect, "Thanks folks. I'll try out the ideas and report back later on what does or doesn't work." The subsequent final report helps newbies and the old hands who have contributed possible solutions get a sense of closure on the thread - without the final report from the OP, everyone is a little uneasy, regardless if the final report doesn't come or weeks or months, when it does come, everyone breathes a big sigh of relief.
