ChroMoVan Material Specs 2

[Maui]

I have a part drawing for a roughing cam dating back to 1945, and it specs out a grade of steel that I've never heard of before: CROMOVAN. I assume that this name stands for an unofficial steel grade containing the alloying elements chrome, molybdenum, and vanadium, among others. It is heat treatable accoring to the requirements listed on the drawing. Unfortunately I have no data sheet for this grade, and the heat treater has never heard of it before either. I already checked Matweb with no luck.

If anyone has it, could they provide a link to a data sheet that lists this grade? Information regarding chemistry, material data, heat treating criteria, etc. are what I am searching for. Any help that you could provide would be appreciated. Thank you.

Try "Woldmans" Engineering Alloys. (thats a book made from paper).

I consulted Woldman's before posting. No luck.

Have you seen this reference to that alloy?

Or this ASTM spec

cloa, I did run across that reference in my search, but didn't see the alloy anywhere in the list. A closer inspection revealed that "cromovan" is listed under Firth-Sterling as their trade name for D2. The ASTM spec that you linked also spells it this way. I suspect that the spelling on the part drawing is probably wrong - they must have added an extra "h".

Thanks for your help!

I just noticed that in my original post I accidently spelled it "cromovan" instead of what appears in the title of this discussion and on the part drawing - "chromovan". My mistake.

I also apologize; and am suprised an older steel is not in Woldmans.

blacksmith, it turns out that it is listed in Woldman's. When I attempted to look it up using the incorrect spelling from the part drawing, I couldn't find it. But if you take out the "h" and spell it "cromovan", there it is.

Look in the Unified Numbering System (UNS) book for UNS # K14675. That UNS # refers you to AMS 6304, AMS 6305, AS7454. AS7455, AS7458, AS7459, MIL-S-24502, SAE J467(17-22-A). Bolting to ASTM A-193 Gr. B16 is made from CrMoVan steel.

Have a good one on me.

I believe that the call out for Chromovan might be a misnomer. The word Chromovan was indiscriminately used to describe any tool steel with Cr, Mo, and V. Cromovan is D-2 as posted above.

If you you could describe the end use of the component it would help in ascertaining which alloy would be best for the call out.
