What is ASTM or ASME of X5CrNiMo 18-12 ? 1

[1973Patrick]

I have a drawing (20 Years old) for an overlay with material X5CrNiMo 18-12.Is this AISI316???
I can not figure out the exact code. Google gives me several options but not the exact coding.
As an example: Google says ..... X5CrNi18-12 but without Mo.

Are you sure the mumbers are correct?
The numbers you quote are similar to BS EN 10088-1 designations.
X5CrNi18-10 is a 304 steel
X5CrNiMo17-12-2 is a 316 steel
Note that if Mo is present an extra numeric digit is added - in this cae "-2" to indicate a nominal 2%Mo.
The BS EN (at least my issue from 2009) doesn't have a X5CrNi18-12 - it has X4CrNi18-12. It has no Mo and so is no a 316 type.

This is not 316 because there is no Mo. Just a higher Ni version of 304.
