Composition difference
Inconel 600 alloy is mainly composed of nickel, chromium and iron, and has good high temperature corrosion resistance and oxidation resistance.
Inconel 690 alloy is a variant of Inconel 600 with a higher chromium content, which makes it have better resistance to sulfidation and corrosion at high temperatures.
Performance difference
Corrosion resistance: Inconel 600 alloy performs well in various corrosive media, especially for reducing, oxidizing and nitriding media. Inconel 690 alloy shows stronger resistance to sulfidation and corrosion at high temperatures and is suitable for sulfur-containing gas environments.
Mechanical properties: Inconel 690 alloy maintains high strength at high temperatures, has good creep rupture strength and metallurgical stability, and will not become brittle when exposed to high temperatures for a long time.
Application field
Inconel 600 alloy: widely used in industries such as petroleum, petrochemical, chemical, machinery, aerospace, marine engineering, environmental protection, medical and food. Due to its good corrosion resistance and mechanical properties, it is suitable for various high temperature environments.
Inconel 690 alloy: Mainly used in nuclear steam generators, coal gasification units, burners, sulfuric acid processing pipelines, petrochemical processing furnaces, heat exchangers, incinerators and radioactive waste treatment equipment. Due to its excellent corrosion resistance and high temperature stability, it is particularly suitable for handling sulfur-containing gases and radioactive waste.
