(OP)
I have an Italian print that calls out a material of 39NiCrMo4.  Do you know what an equivalent US steel would be for this material?

Any help you can provide would be appreciated.

RE: 39 nicrmo 4 us equivalent

I believe ASTM 9840

RE: 39 nicrmo 4 us equivalent

39NiCrMo3 (1.6510) is the current designation according to EN 10083-3.  It is roughly equivalent to grade 9840, which appears in ASTM A 519 (seamless tubes) and not much else.  It has been relegated to the former SAE standards in SAE J1249.
