Hello Arshad,

I just checked my database(you can find it at http://www.matdat.com and there are about 30-40 instances of AISI304, AISI304ELC and AISI304H material.

Different heat treatments, different testing temperatures.

All data are from relevant literature and are result of monotonic,cyclic/fatigue tests (not general, basic data that you get from suppliers).

Take a look at the database. High-alloy steels are for paying users only, but if you think this may be useful for you, contact me and I will provide you full access to the database.

Regards,

Robert

thanks dr robert you have been very helpful. But the matdat site is not opening. actually I have performed tensile tests on AISI 304 samples in accordance with ASTM E8M twice and on both instances I found % elongations to be more than 105%. I just wanted to validate either thgough such published literature or otherwise in case some other expert has also found a similar resluts?? can you further comment and or provide some other reference plx.

Thank you once again.

Hi Arshad,

Seems to be very soft. What about Tensile & Yield strength. Did you have values asper STD. Which form of sample you had - Rod or Sheet metal

Can you confirm metallurgical condition of your sample. Is it annealed after Hot finishing. ASTM STD A276 has reference for 3 condition - Annealed (with hot & cold finish), relatively severe cold worked & relatively light cold worked).

In hot finished + Annnealed condition, for thickness around 3 mm, we observed 55 - 60 % & specification asper ASTM was 30% minimum.

Hello again,

I checked the data for AISI304 and unfortunately, elongation was not provided in original references. However, for most materials that I mentioned, Reduction of area at fracture is known.

If that can be of use to you and you would still like access to the data, let me know.

Btw. what did you mean by "matdat site is not opening"?

I was not aware that the site was inaccessible.

Best regards,

Robert

Depends on the reached yield strength after rolling, the higher the yield strength the lower the elongation...

Yeah Mr. robert I could now access the matdat site but it was not of much help. thanks any ways. by the way I have tested commercially available hot rolled AISI-304 plates 2.95 mm thick.
