Material Description
In625 alloy comprises nickel alloyed with chromium of mass fraction up to 23% and molybdenum up to 10%, along with other minor elements. The addition of niobium, acting with molybdenum, gives the alloy high strength and toughness in the annealed condition. In625 has a wide range of applications within industry and is particularly suitable for seawater applications and applications where corrosion and oxidation resistance at high temperatures is required. Similar to In718 which is suitable for applications where good tensile, creep, and rupture strength is required.
Material Properties • High creep resistance • Very high corrosion and oxidation resistance at high temperatures • High fatigue strength in seawater • Excellent welding characteristics • Nonmagnetic | Applications • Automotive • Aerospace, defense, and nuclear • Chemical process industry • Marine engineering, Oil and gas industry • Seawater heat exchangers |
