Alloy 686 is shown to have good metallurgical FABRICATION OF HASTELLOY CORROSION-RESISTANT industry standard, C-276 alloy. Its forming, welding and machining characteristics are similar to C-276 alloy. Ask for Bulletin H-2111 HASTELLOY C-276 alloy has excellent resistance to pitting, stress corrosion cracking, and acid environments. It has exceptional resistance to a wide variety of chemical process environments,
Corrosion Resistance Hastelloy C276 alloy is resisting against strong oxidizing agents like zinc, ammonium, iron and copper chlorides, acetic, formic, phosphoric, nitric, sulphuric, hydrofluoric, acids, hypochlorite, ferric and cupric salt solutions, acetic anhydride, sea water. HASTELLOY C276 UNS N10276Alloy C-276 also has excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres up to 1900°F. Alloy C-276 has exceptional resistance to a wide variety of chemical environments. Characteristics. HASTELLOY C276 is one of the few alloys resistant to wet chloride gas, hypochlorite and chlorine dioxide solutions. Hastelloy C-276 Nickel Alloy, UNS N10276, Alloy C276 Hastelloy C276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The high nickel and molybdenum contents make the nickel steel alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media.
Feb 16, 2017 · Hastelloy C-276 resists corrosion in some of the harshest environments by Enerquip Administrator Feb 16, 2017 Before choosing a shell and tube heat exchanger for your operation, its crucial to know the strengths and weaknesses of the many alloy options available to you. Hastelloy C276-Zibo wuden alloy material technology Co., LtdHastelloy C-276 is a tungsten-containing nickel-chromium-molybdenum alloy with very low content of silicon and carbon. The high content of molybdenum and chromium makes Hastelloy C-276 resistant to a variety of chemical media, including reductant, such as phosphoric acid, hydrochloric acid, sulfuric acid, chlorine gas, organic or inorganic chlorine-containing media. High Performance Hastelloy C-276 AlloyHastelloy C-276 is resistant to the formation of grain boundary precipitates, so in welding conditions, it is suitable for most chemical process applications. Another benefit of using this alloy is that it has excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres. High strength at extremely high temperatures.
Hastelloy alloy C-276 was found to be about 109 Kcal/mole. This value is much higher than the value of the activation energy for self-diffusion of Ni (Qso s 66 Kcal/mole) or the activation energy for diffusion in nickel of any of the major alloying elements present in this alloy (6).
