5, Has good creep rupture strength and is recommended for use in environments above 700 °C

Metallographic Structure


600 is a face-centered cubic crystal structure

Corrosion Resistance


Alloy 600 is corrosion resistant to a variety of corrosive media. The composition of chromium gives the alloy better corrosion resistance under oxidizing conditions than nickel 99.2 (alloy 200) and nickel 99.2 (alloy 201, low carbon). At the same time, the higher nickel content makes the alloy have good corrosion resistance in reducing conditions and alkaline solution, and can effectively prevent chlorine-iron stress corrosion cracking. Alloy 600 has good corrosion resistance in organic acids such as acetic acid, acetic acid, formic acid, and stearic acid, and has moderate corrosion resistance in inorganic acids. It has excellent corrosion resistance in high-purity water used in primary and secondary recycling in nuclear reactors. The outstanding performance of the 600 is resistant to corrosion by dry chlorine and hydrogen chloride at temperatures up to 650 °C. At high temperatures, the returned and solid solution treated alloys have excellent resistance to oxidative spalling and high strength in air. The alloy is also resistant to ammonia and nitriding, carburizing atmospheres, but when the redox conditions alternate, the alloy will be corroded by some oxidizing medium (such as green death liquid)

Applications


1, Thermowell in an erosive atmosphere
2, Vinyl chloride monomer production: anti-chlorine, hydrogen chloride, oxidation and carbonization corrosion
3, Uranium oxidation to hexafluoride: anti-hydrogen fluoride
4, The production and use of corrosive alkali metals, especially in the use of sulfides
5, Making titanium dioxide by chlorine method
6, Production of organic or inorganic chlorides and fluorides: resistance to chlorine and fluorine gases
7, Nuclear reactor
8, Ferrules and components in heat treatment furnaces, especially in carbonized and nitriding atmospheres
9, Catalytic regenerators in petrochemical production are recommended for use in applications above 700 °C for long service life.
