NS322

Detail

NS322

Materialgrade: NS322 corrosion resistant alloy

US grade: UNS N10665

Equivalent grade: Hastelloy B2

German grade: W,Nr,2.4617

I. overview:

1, NS322 (Hastelloy B2. N10665) alloy is acorrosion-resistant, solid solution nickel-molybdenum alloy. The NS322 has thefollowing features:

(1) Control the iron content and chromiumelement at the lowest level to prevent the formation of β-phase Ni 4 Mo.

(2) Excellent corrosion resistance to areducing environment.

(3) Excellent resistance to moderateconcentrations of sulfuric acid and many non-oxidizing acids,

(4) very good resistance to chloride ionreduction stress corrosion cracking (SCC),

(5) Excellent resistance to various organicacid corrosion 2. Chemical composition of NS322 2.chemicalcomposition:: %
