3. Has excellent resistance to dry chlorine and hydrogen chloride gas corrosion

4. Has excellent mechanical properties at minus zero, room temperature, and high temperature

5. Has excellent resistance to creep and fracture strength, recommended for use in700Working environment above ℃.

Inconel 600The metallographic structure:

600 It has a face centered cubic lattice structure.

Inconel 600Corrosion resistance:
600Alloys have corrosion resistance to various corrosive media. The composition of chromium makes the alloy better than nickel under oxidation conditions99.2 (合金200)And nickel 99.2（合金201,Low carbon has better corrosion resistance. At the same time, the higher nickel content makes the alloy have good corrosion resistance under reducing conditions and alkaline solutions, and can effectively prevent chlorine-Iron stress corrosion cracking. 600Alloys have good corrosion resistance in organic acids such as acetic acid, acetic acid, formic acid, and stearic acid, and moderate corrosion resistance in inorganic acids. The high-purity water used in the first and second cycles of nuclear reactors has excellent corrosion resistance. 600The outstanding performance is the ability to resist the corrosion of dry chlorine gas and hydrogen chloride, and can be applied at temperatures up to 650℃At high temperatures, alloys in annealed and solution treated states exhibit excellent oxidation resistance and high strength in air. This alloy can also resist ammonia gas, nitriding, and carburizing atmospheres, but when the redox conditions alternate, the alloy will be partially corroded by oxidizing media (such as green death solution)
