What materials for a boiler, if any, do not require a deaerator? I'm imagining a portable boiler/turbine unit that burns wood and creates steam for a turbine, generating electricity.

I was planning on using freshwater from a river or lake. (A simple filter will remove particulate matter and minerals.)

But then I came across something called a Deaerator.

Basically, the deaerator removes oxygen and carbon dioxide from the water. Those substances often dissolve in the water and, in a boiler, can cause metal corrosion.

So I'd like to choose a material that doesn't require this, if possible. Titanium? Bronze? Carbon-carbon? Iron-Nickle like they use in jet engines?

Edit: For the curious, this question arose from studying old steam trains. Pretty sure they did not de-aerate the feedwater there and just let boiler lifetime suffer. I'm wondering if some modern "miracle" material, maybe carbon composites, can eliminate the need for de-aeration.
There are many more common alloys in the Inconel , Hastelloy , and Incoloy families. And some odd balls like MP35N, 5o:5o Cr- Ni, Vitallium , and others. Titanum won't take the heat. For all of these materials; if you need to ask the price ,you can't afford them.
