Database of Charpy Data - Where to find

[CR100]

I am sure this exists and don't mind paying for it. I am looking for a comparison of Charpy test results of different steels (4130,4330,9310,3312,4340,300M) at different hardnesses. I have searched through ASM International and found nothing.

I would try the public web portal for NASA and the bureau of National Standards. There are probably numerous old technical publications regarding the list of steels and associated heat treatments. You will probably find this data in scattered form in several technical papers that are in the public domain.

Good luck.

There are many old military reports (NASA, Air Force, NWL) about this, but finding data that gives you the melting method (cleanliness rating), chemistry, and specifics of the HT will be difficult.
There is a lot of data, but comparing data from different report will be problematic.

ASM Handbook 8th addition , Vol 1, ( 1961) has all that data; I did not see the 300M, it is likely in a different section. And as noted the data is all available , but apparently not in one place on the internet.

300M should be in Vol 3 (of the red books) with specialty materials and ultra high strength steels.

blacksmith37 and EdStainless, I don't have the printed version I do have access to the online version. Volume 1 is Properties and Selection: Irons, Steels, and High-Performance Alloys. Is this what your seeing? Vol 3 is Alloy Phase Diagrams.

 

EdS,
The red edition is best!

CR100 you must be looking at the older (blue) ones.
One problem is that any data that you find is likely to be 20-40 years old (or older).
This may not reflect what is being produced today.

Thank you I will reach out to ASM.

You might want to talk to a specialty heattreater that does a lot of aerospace work (maybe Solar).
And talking with a steel mill that makes all of these grades could also be useful.
Some of these alloys (300M) are only made as remelted material, many of them are offered as both air melt and remelted. This can have significant bearing on the toughness, especially if you are looking at over 175ksi UTS.
