Need tool steel identification.

Need tool steel identification.

(OP)
I've got a quantity of tool steel marked `U S Ultra' and can't find it listed anywhere, can anyone help me with the specifications and recomended uses ?.

RE: Need tool steel identification.

I don't find this listed either.  If you could get access to the reference book "Woldman's Engineering Alloys" it might be listed.


There is a current industry project in Japan "Ultra Steels"

RE: Need tool steel identification.

Nothing in Woldman's.  There is an entire line of tool steels called Ultra, about a dozen different grades.
Get an analysis and harden a sample.  See what it is.

RE: Need tool steel identification.

I found it in Woldmans. It is basically a type H-11 tool steel, and is registered under U.N. Alloy Steel Corp. They are in Revere, MA 02151. Hope this helps.
