Is there such a thing as Aircraft Quality type 321 stainless steel sheet & coil, and if so, what are the specific requirements?

Thank you Ed and thank you McGuire. Hamid Naziri

Dr. McGuire, What annealing temp and time would you suggest? Also, can this be done on a continuous annealing line or would it require a batch anneal? Thank you very much in advance. Hamid Naziri

It's actually Cb (Nb) stabilized. Type 321 is Ti stabilized.

Is there such a thing as "Thermally stabilized stainless steel type 347"?

Where can I get a rolling chart or a table that compares the mechanical properties vs percentage of cold reduction for stainless steel type 317L?

Thank you both for your inputs.

Happy New Year. I was stumped by a customer asking how it is determined what residual elements should be reported in a heat analysis. Is there any documentation to show, i.e., how ASTM, AISI or AMS standards agreed to require certain elements and not others?

What type of stainless steel is most suitable for use as electrodes in water deionization process?

Metengr, Thank you for your response. I almost knew the answer as soon as I posted the question. I guess what I was hoping for was an absolute minimum temperature regardless of alloy content and time at temperature for a set amount of prior cold work. I think I can predict the answer to this...

What is the recrystallization temperature for type 430 cold rolled sheet when being annealed?

Is there such a thing as "Nitrogen contamination in type 321 stainless steel during the annealing process"?

Is there such a thing as "Nitrogen contamination in type 321 stainless steel during annealing process"?

I have another question on this subject. Has any of you heard of a 2% max ferrite 17-7PH? I'm sure if it's possible, it would have to be controlled with the chemistry. But, what would this do to the mechanical properties after heat treat? Hamid

Thank you all for replying. You were all very educating and gave me more than enough information. I can't wait to see the results of Nick's study. hamid

Is it normal to find any carbide precipitation in the grain boundries of stainless steel type 17-7PH in the annealed or heat treated condition?

Thanks Cory, but I'm looking for the stainless steels or nonferrous alloys that would complete 1000 hours of ASTM B 117 or B 368 without any visible corrosion or pits. Regards, Hamid

Are there any stainless steels or corrosion resistant metals/alloys that withstand 1000 hours of salt spray testing?

You would want some Ti available to tie up carbon, otherwise chromium carbide is going to form if the carbon is not tied up. That's what you don't want to happen because formation of chromium carbide in 300 series stainless steels means that the material is sensotized. I think in recent years...
