I think that the term "Hi-Ten" can be used flexibly, i.e. that there is no standard numerical specification for the tensile strength or yield strength of steel that is named "hi ten".
I also believe the same applies to "hi protein" as applied to this granola for example, which may have a higher protein content than most other granola, but which still is very high-carbohydrate food source.
But maybe there was some international standard for the "precision steel" that the label describes on my Steyr Clubman seat tube(?).
Or maybe for the "titanium alloy steel" that some 1990's K-mart Huffy bikes were labeled with...
