It looks like it is all no good for blades, and not really much use for hardware. Chromolloy is tough and corrosion resistant, but isn't good for knives.

I think 4130 would make good hammers.

as i know nothing about forge welding could i weld in a piece of w2 or 1075 and make an axe out of the 4130

Yes you can forge weld a piece of HC steel for the bit of the ax. Done all the time. 4130 can be a bit stiff under the hammer and the moly makes it a bit red short. It canbe done just have to do it carefully. Not really a beginner project. It would be easier if you use a piece of mild and do the same thing. The 17-4 PH is precipitation hardening stainless. Not good for knives and it is really hard on tooling to mill, cut or grind.

Could crack under the hammer if over heated
