Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If hollow bars over wire size
Larger cross-sections may classify as bars, not tubes if solid-like.
If cold-formed seamless
Seamless cold-drawn alloy tubes separate from welded.
If certain nickel alloy specifics
Special alloys may have statistical suffixes.
