C-276 Hastelloy belongs to nickel-molybdenum-chromium-iron-tungsten-based nickel-based alloy, is the most resistant to a modern metal material. Main moisture-resistant chlorine,
a variety of oxidizing chloride, chloride solution, sulfuric acid and oxidizing salt, in the low temperature and medium temperature hydrochloric acid have good corrosion resistance.
Therefore, nearly three decades, in the harsh corrosive environment, such as chemical, petrochemical, flue gas desulfurization, pulp and paper,
environmental protection and other industrial areas have a very wide range of applications.
Hastelloy alloys include nickel-molybdenum Hastelloy B-2, nickel-chromium molybdenum Hastelloy C-4 and so on.
Hastelloy grades include the following grades:
1.HASTELLOY B-2 nickel-molybdenum alloy, in the reducing environment has excellent corrosion resistance HASTELLOY B-3 B-2 upgraded version of any temperature and concentration of hydrochloric acid have excellent corrosion resistance.
2.HASTELLOY C-4 better thermal stability, 650-1040 degrees Celsius has good toughness and corrosion resistance.
3.HASTELLOY C-22 is resistant to uniform corrosion in oxidizing media better than C-4 and C-276, excellent resistance to localized corrosion. HASTELLOY C-276 has good resistance to oxidative and moderate reducing corrosion,excellent resistance to stress Corrosion ability. HASTELLOY C-2000 The most comprehensive corrosion resistance alloy, in the oxidation and reduction environment have excellent resistance to uniform corrosion.
4.HASTELLOY G-30 upgrade products, corrosion resistance and thermal stability better HASTELLOY G-30 high chromium content nickel-based alloy, in the phosphoric acid and other strong oxidizing mixed acid medium performance.
5.HASTELLOY X integrated high strength, anti-oxidation and easy processing characteristics of each grade has a specific chemical composition, mechanical properties, have their own strengths, can not be generalized what characteristics of Hastelloy.

Hastelloy C276 Hex Nuts characteristic
① in the oxidation and reduction of two atmosphere state, the majority of corrosive media with excellent corrosion resistance.
② excellent resistance to pitting, crevice corrosion and stress cracking corrosion performance.
Hastelloy is suitable for a variety of chemical industries containing oxidizing and reducing media. Higher molybdenum and chromium content make the alloy resistant to chloride ion corrosion,
tungsten elements to further improve the corrosion resistance. At the same time C-276 Hastelloy tube is only one of several moisture-resistant chlorine,
hypochlorite and chlorine dioxide solution corrosion of one of the materials, high concentrations of chloride solution such as ferric chloride and copper chloride Significant corrosion resistance.
Hastelloy C276 Military Green Zinc Hex Nuts Application areas:heat exchangers, bellows compensators, chemical equipment, flue gas desulfurization and denitrification, paper industry, aerospace applications, acidic environment.
