CORROSION-RESISTING ALLOY

In order to improve various properties relating to corrosion, it is proposed to increase the molybdenum content of a known Ni-Cr-Fe alloy and to add nitrogen within certain limits to the alloy. This will considerably increase the pitting corrosion potential and the critical crevice corrosion and pit...

Summary:In order to improve various properties relating to corrosion, it is proposed to increase the molybdenum content of a known Ni-Cr-Fe alloy and to add nitrogen within certain limits to the alloy. This will considerably increase the pitting corrosion potential and the critical crevice corrosion and pitting corrosion temperatures whereas the resistance of the alloy to commercially pure phosphoric acid has not been decreased.
