IInconel
High Temperature Alloy
◆Inconel600 (N06600) has corrosion resistance to various corrosive media, it also has good creep rupture strength, recommended for the working environment below 700 ℃. It is mainly used in the field of production and use of corrosive alkali metals, especially in environments where sulfides are used.
◆An important performance of Inconel601 (N06601) is that it has oxidation resistance and good carbonization resistance when the temperature is as high as 1180 ° C. It is mainly used in heat treatment processing parts, exhaust system parts, and oxygen reheaters.
◆Inconel625 (N06625Ns336) exhibits excellent corrosion resistance in many media, and the soft annealed low-carbon alloy 625 is widely used in the chemical process industry, where it contacts seawater and withstands high mechanical stress.
◆Inconel725 has strong stress corrosion resistance and is suitable for pipe fittings and marine vessels.
◆Inconel690 has anti-oxidation and anti-corrosion properties, and is suitable for petrochemical, metallurgy, nuclear energy, etc.
