Alloy 600 is an excellent candidate for many uses in extremely high temperature and highly corrosive environments. Alloy 600 is a nickel-chromium alloy designed for use from cryogenic to elevated temperatures in the range of 2000°F (1093°C). The high nickel content of the alloy enables it to retain to corrosion by a number of organic and inorganic compounds. The finer grain structure of the cold finished tube, additionally, brings better corrosion resistance, which includes higher fatigue and impact strength values. Alloy 600 is relatively un-attacked by the majority of neutral and alkaline salt solutions and is used in some caustic environments. The alloy resists steam and mixtures of steam, air and carbon dioxide. Applications: Nuclear power plants. Heat exchangers. Thermocouple sheaths. Chemical & food processing equipment. Ethylene dichloride (EDC) cracking tubes. Conversion of uranium dioxide to tetrafluoride in contact with hydrofluoric acid. Production of caustic alkalis particularly in the presence of sulfur compounds. Reactor vessels and heat exchanger tubing used in the production of vinyl chloride. Process equipment used in the production of chlorinated and fluorinated hydrocarbons. In nuclear reactors uses are for such components as control rod inlet stub tubes, reactor vessel components and seals, steam dryers and d separators in boiling water reactors. In pressurized water reactors it is used for control rod guide tubes and steam generator baffle plates etc. Furnace retort seals, fans and fixtures. Roller hearths and radiant tubes, in carbon nitriding processes especially.ASTM B163, ASTM B167Alloy 600 (UNS N06600) Composition %
