I saw a steel stamp on a valve today that read A108N – does this indicate the material? I remember that it’s usually not something like WCB or CF8, right? What is this standard?

It’s best to take a picture to take a look at the whole thing

It should be specified in the ASTM A108 standard; you can check that standard

ASTM A108-2013: Specifications for cold-worked carbon steel and alloy steel bars. The original poster made a mistake – it should be A105 (N?). This is roughly equivalent to domestic 20–25# forgings~~~
