Valve seat materials?

[JimSvarv]

Hello!

I'm wondering what materials I could use for valve seats?
I have difficulty finding cast iron in my location and bearing bronze is quite expensive, especially for a simple project as I had in mind.

Could I just use normal construction steel? I have free machining lead steel and ɓrass too if it would work better?

Maybe I could find some junk break rotor and use, but it would tricky to make pieces that could be easy to hold.

Watching for interest, ................. how ever aren't most seat slightly hard(ened) ??
However given what material you have on hand I would say leaded steal....

Webster type of engine.
I was hoping I could make the seats/guides in the valve blocks directly without valve cages.
