Definitions

  • FIG. 4 has been presented to demonstate that the iron content of the claimed alloys can be increased to about 14% without loss of resistance to lead compound attack. This is economically important as it enables the alloy to be fabricated from more economical alloys such as ferrochromium and ferro-titanium. Iron is, of course, per se the cheapest constituent of the alloy. ABSTRACT OF THE DISCLOSURE It is important that these alloys have the maximum.
