Would like to strengthen iron electroform

[Robertsolo]

I am looking at electroforming a family of parts from Iron the strength of Iron electroforms ranges from 50,000 PSI Tensile to 65,000 PSI Tensile.
This is basically pure iron with a fine grain structure (no significant amount of Carbon).
Adding Nickle is not too difficult (it has been done and there are instructions available).
I would like to increase the strength of the material , doubling it would open up a lot of possibilities for other uses , Would adding nickle and some form of thermal processing increase the strength ? How much Nickle ? What kind of thermal processing ?

What other properties do you want?
Ductility?
Toughness?
This is very basic steel making. Go back and look at the strengthening effect of various additions to Fe.
Why not add C? You could do it by carburizing in an atmosphere.
And then add a diffusion step to get it more uniformly distributed.
If you keep the total C below about 0.20% then you don't need to Q&T.
