1,330°C High Temperature Nickel Alloy Material Nickel Alloy 718 Inconel Pipe

Product Introduction

Inconel 718 tube is a high-performance nickel chromium iron-based precipitation hardening alloy tube with excellent high-temperature strength, oxidation resistance, and corrosion resistance. Its main components include nickel (50% -55%), chromium (17% -21%), iron (balance), molybdenum (2.8% -3.3%), niobium (4.5% -5.75%), aluminum (0.2% -1%), and titanium (0.3% -1.3%), which endow Inconel 718 tube with excellent corrosion resistance, especially in high temperature and corrosive environments. Inconel 718 tube maintains good mechanical properties, including high strength and creep resistance, even at temperatures up to 1300 ° F (700 ° C). Its excellent corrosion resistance makes it perform well in various corrosive environments, including seawater, acidic solutions, and alkaline solutions. Inconel 718 tube is widely used in aerospace, chemical, marine engineering, oil and gas industries, and is used to manufacture key components such as exhaust systems, heat exchangers, reactors, and piping systems for aircraft engines.
