The chemical composition of Inconel 625 flange of Inchel 625 of the Ministry of Chemical Industry of Hancher A182: alloy% NiCrMoNbFeFeAlAlTiCMnSiCoPsulphurInconel 625 minimum balance 2083.15 maximum 23104.1518.104.22.168.50.510.0150.015625 alloy in many media Both show excellent corrosion resistance. Excellent resistance to pitting, crevice corrosion, intergranular corrosion and erosion in chloride media. It has good resistance to inorganic acid corrosion, such as nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid, etc. At the same time, it also has resistance to alkali and organic acid corrosion in the oxidation and reduction environment. Effective resistance to chloride-reducing stress corrosion cracking. It produces almost no corrosion in seawater and industrial gas environments, and has high corrosion resistance to seawater and salt solutions, even at high temperatures. No sensitivity during welding
. Resistant to carbonization and oxidation in static or cyclic environments, and resistant to corrosion by chlorine-containing gases.
