... acids as the Ni-Cr-Mo alloys, because of its lower molybdenum content, it is better than stainless steels in this respect. It also exhibits moderately high resistance to chloride-induced phenomena, such as pitting, crevice corrosion, and stress-corrosion cracking. Alloy 600 (N06600) is used as an...
