FR10 equivalent
(OP)
I have a print specifying FR10 for a cold headed part. I am looking for the SAE or ANSI equivalent to FR10.

RE: FR10 equivalent
I don't understand why you don't ask the customer for more information about the parts you are quoting. If they gave you a part drawing, and you have questions, why don't you contact your customer?
Lastly, this is about the 10th time on this site that you have requested information regarding substitution of various materials. It seems that it is time for you and your employer to obtain the necessary references to conduct your business. Relying on the collective experience and kindness of strangers seems like a poor practice.

I think you should consider a couple, relatively low-cost, references. These probably will cover 90% of what you will need except for proprietary standards from companies like GM, Toyota, etc.

RE: FR10 equivalent
If you were to purchase a single reference book for the comparison of international steel designations, which would it be?
Stahlschlüssel
Worldwide Guide to Equivalent Irons and Steels, 5th Edition, published by ASM International
Or ASTM's Handbook of Comparative World Steel Standards: Fourth Edition
Any of these may be considered to be “relatively low-cost reference” to some. To me, spending $200 to over $400 on a book I’ll use a few times a year is a chunk of change.

Can you tell me what it says about steel DIN 1.8550. I've been confused with what I've found in my searches and, according to the index that's accessible through the ASM website, it's not in there.
Some sites tell me it includes nickel. Others indicate it doesn't
This has been my dilemma regarding this purchase. I haven't found a single source with everything I need. Our customer's prints come from all over the world and some of the materials called out are obsolete references.
RE: FR10 equivalent
Grade 34CrAlNi7-10 (1.8550) appears in the old DIN standard DIN 17211 (as 34CrAlNi7) and in the current Euronorm standard DIN EN 10085. The exact composition is as follows:
C = 0.30-0.37
Si = 0.40 max
Mn = 0.40-0.70
P = 0.025 max
S = 0.035 max
Cr = 1.50-1.80
Mo = 0.15-0.25
Ni = 0.85-1.15
Al = 0.80-1.20
Regarding the best cross-referencing resource, it is difficult for me to narrow down the list to only one. All three of the items that you mentioned have been recently revised, and are quite thorough and easy-to-use. I would probably default to the ASM guide over the other two if forced to pick only one.
RE: FR10 equivalent
This was very helpful.
An old saying that seems to apply to me more than I'd like is, "A man with one watch always knows what time it is. A man with two is never sure."
I was fine with the composition you just provided until I stumbled on one without the nickel. It grouped four steels in EN10085:2001: 1.8505, 1.8507, 1.8550 and 1.8509. Only 1.8509 included the nickel. Levels of C, Cr, and Mo varied slightly between them.
