Introduction

UNS N06622, also known as Inconel 622, is a nickel-based alloy is with nickel as the main component. Due to the strengthening effect of molybdenum and niobium solid solution contained in nickel-chromium alloy, it has ultra-high strength and extraordinary fatigue resistance at low temperatures to 1093°C, and is widely used in the aviation industry. Although the alloy is designed to adapt to the strength of high temperature environments, the high content of chromium and molybdenum in the alloy has high corrosion resistance to many corrosive media, from highly oxidizing environments to general corrosive environments, and shows excellent corrosion resistance. INCONEL 625 also has a strong anti-corrosion effect on chloride-contaminated media such as seawater, geothermal water, neutral salt and brine
