Normally if the sticker says three main tubes are chromoly, that is code for the rest being high ten steel. If the fork has a chromoly sticker on it, then the rest is chromoly.
First 820 came out in 1987, check your serial # and specs on the vintage trek site. Specs changed just about every year, sometimes improved, sometimes for the worse.
