A108-1045

[sks4338]

I saw a valve part specification like this.

"Key: Carbon steel, A108-1045"

But you can't find 1045 in ASTM A108.

So I think this is a customry notation, combined with ASTM and AISI. Then, if want to know about this material, what publication do I have to look up?

AISI no longer maintains any standards for steel chemical composition. ASTM and SAE do. Section 7 of ASTM A 108 lists the applicable references for chemical compositions. ASTM A 29 is the probably the most common reference for ASTM A 108, since it defines the requirements for the hot-rolled bars that are turned into cold-finished bars according to ASTM A 108. Grade 1045 appears in ASTM A 29.

If you are using the internet, you can also obtain mechanical properties free from the web site below for Grade 1045 (AISI Type 1045);
