| Alloy 625 is a low-carbon nickel chromium molybdenum niobium alloy with excellent corrosion resistance to various corrosive media, without magnetism; it operates in rings from low temperature to 1093 ºC (2000 ° F) The environment has good strength, toughness, and excellent fatigue resistance, thanks to low carbon content, solid solution treatment, and the addition of elements such as niobium and molybdenum. Alloy 625 High level of uniform corrosion resistance and excellent resistance to chloride ion pitting and stress corrosion in both oxidizing and non oxidizing environments. This alloy also has excellent processing and welding properties Performance. | ||||||||||||
