astm designation rules

[Johnwoo1991]

Is it correct for the AISI 410 material according to ASTM A479 specification to designate it as "ASTM A479 Grade 410 (or Tp 410)" or is it better ASTM A479 UNS S41000? Today I had a debate with another technician on this topic who considered only the second designation valid.

You can use either as both are given, but note "Type 410" is the terminology consistent with the spec. I would use "Type 410" because people think in terms of the generic steel name rather than the specific UNS designation.

If you are referring to by the ASTM spec number, then using the verbiage from the spec (type or grade depending on the spec) is fine.
Though either would be acceptable.
IF this was a standalone reference then the UNS number would be the preferred designation.
