Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

Well we know it isn't carbon (not at that price). A magnet will tell you if it's steel (which I suspect it is) or aluminum.

Chrome-moly is a type of steel, so is what they often call Hi-tensile, or Hi-ten and other trademarks. There are a number of steel alloys where metals like chrome, molybdenum and nickle (3 most commonly used) are added to improve the strength and other properties. The only way to have any idea which type of steel your frame is made of is to read the specs, or send off a small piece for chemical analysis (cost about $500.00).
