The makers of 8630 melted some nickel into the mix along with chrome and molybdenum in order to give 8630 specific qualities.
Kaisei describes this steel as "heat-treated," and this could mean many things.
Apparently, Keirin frame makers use 8630 for their high end frames.
A few years ago I visited the United Bicycle Institute in Ashland, Oregon.
I highy recommend UBI to anyone interested in learning how to make a bicycle frame.
