I. Overview of Hastelloy B2(N10665, 2.4617):
Hastelloy B2（N10665，2.4617）is a corrosion-resistant, solid-solution nickel-molybdenumalloy.
1. Main Features:
(1) Control the minimum content of iron andchromium to prevent the formation of β-phase Ni4Mo.
(2) Excellent corrosion resistance to reducingenvironment.
(3) Excellent resistance to corrosiveness ofmedium sulfuric acid and many non-oxidizing acids
(4) Good resistance to chloride ion reductionstress corrosion cracking (SCC).
(5) Excellent resistance to various organicacids.
