NS333

Detail

NS333

Materialgrade: NS333 corrosion resistant alloys

American grades: UNS N06645

Equivalent grades: Hastelloy C

Germany Grade: W,Nr,2.4610

I. overview:

1, NS333 is a nickel-chromium-molybdenumalloy containing tungsten, which has extremely low silicon and carbon content.The characteristics of the NS333 are:

(1) Excellent corrosion resistance to mostcorrosive media in the oxidized and reduced state,

(2) Excellent resistance to pittingcorrosion, crevice corrosion and stress corrosion cracking,

2. alloy applicationareas:

Widely used in the chemical andpetrochemical industries, such as in the contact with chloride-containingorganic components and catalytic systems. This material is especially suitablefor use in high temperature, inorganic and organic acids (such as formic acidand acetic acid) and seawater corrosive environments. Other application areas:

(1) pulp and paper industry, such asdigestion and bleaching containers

(2) washing towers in FGD systems,reheaters, wet steam fans, etc,

(3) equipment and components operating inacid gas environment

(4 ), reactor for acetic acid and acidicproducts

(5) sulfuric acid condenser

(6) methylene diphenyl isocyanate (MDI)

(7) production and processing of impurephosphoric acid
