Kaisei 8630 vs. 4130
Hi all,

I'm curious what the metallurgical differences of NiCrMo and CrMo translate to in terms of frame building. Is 8630 stiffer? Stronger? More corrosion resistant? Different brazing temperatures? Kaisei draws both steels to the same wall thicknesses, so I'm wondering what this translates to on the bike/in the jig.
