    Oxide resistant, ferrous alloys

    "Oxidation at what temp? At lower temps adding enough Si or Al to steel will get oxidation resistance. Though you would be better off sticking to Fe-Cr martinsitic alloys. You may find that you don't need to go to 18%Cr, in many applications 5-9%Cr provided adequate corrosion resistance. Are you...

    Oxide resistant, ferrous alloys

    I was wondering, if you people know of any cheaply made ferrous alloys with a reasonable resistance to oxidation (since commercial stainless steel is way beyond the scope of homemade products). P.D: my homebrew kilns can easily melt iron and titanium.
