a bunch of them, most made by me, a couple made by others
tange 1000 was straight gauge chromoly down tube, seat tube and top tube. The stays and and fork are likely HiTensile steel. It would be considered a lower end frame by most. For touring it will likely be a bit stiff and a bit heavy. It wouldn't be my first choice for a MTB tourer, but if it was what I had to ride, I would ride it and not give it another thought.
