Hastelloy C-276 wire , rod
Hastelloy C276 alloy is a nickel-molybdenum-chromium wrought alloy which has exceptional resistance to many of the most severe media. Hastelloy C276 is an improved version of Hastelloy C and has improved fabricability.
Alloy C276 has exceptional resistance to many of the most severe media encountered in chemical processing, including reducing and oxidizing acids, highly oxidizing neutral and acid chlorides, solvents, formic and acetic acids, acetic anhydride, wet chlorine gas, hypochlorites, and chlorine solutions. It has excellent resistance to phosphoric acid. Alloy C276 also resists sulfide stress cracking and stresscorrosion cracking in sour gas environments containing hydrogen sulfide, carbon dioxide, and chlorides.
Hastelloy C276 is used in flue gas desulfurization systems because of its excellent resistance to sulfur compounds and chloride ions encountered in most scrubbers. Alloy C276 has excellent resistance to pitting and to stress corrosion cracking. It is also one of the few materials that withstand the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide.

Hastelloy C-276 Physical properties:
Hastelloy C-276 Alloy m inimum mechanical properties in the room temperature
Hastelloy C-276 Characteristic
1.Excellent corrosion resistance to most of corrosion media in oxidation and reduction environments.
2.Excellent resist pitting, crevice corrosion and stress corrosion cracking performance.
Hastelloy C-276 Metallurgical structure
C276 is face-centered cubic lattice structure.
Hastelloy C-276 Corrosion resistance
C276 alloy suit for many kinds of chemical process industry which contain the oxidizing medium and reductant. High molybdenum and chromium content make it can resist the chloride corrosion, and tungsten make it corrosion resistance better.C276 is one of a few material that can resist the corrosion of most chlorine, hypochlorite and chlorine dioxide, this alloy have prominent corrosion resistance to high concentration chlorate( iron chloride and copper chloride).
Hastelloy C-276 Application field:
C276 is widely used in the chemical field and petrifaction field, such as the element of chloride organic and catalyze system.This material especially suit for high temperature environment, impure inorganic acid and organic acid (such as formic acid and acetic acid), sea-water corrosion environment.
The digester and bleacher in the use of paper pulp and paper making industry.
Absorption tower, re-heater and fan in the FGD system.
The equipment and parts in the use of acidic gas environments.
