Differences between Inconel 600/625 metal plates
Differences between Inconel 600/625 metal plates
The main difference between Inconel 600 and 625 plates lies in their composition. 625 has a higher chromium and molybdenum content, resulting in superior overall corrosion resistance, strength, and toughness. Inconel 600 is a nickel-chromium alloy that performs well in high-temperature and high-chloride environments; while Inconel 625, due to its enhanced resistance to chloride stress corrosion cracking and pitting, is more suitable for harsh corrosive environments such as marine or chemical processing environments.
What is the difference between Grade 1 and Grade 2 Inconel 625?
Grade 2 Inconel 625 is supplied in the solution-annealed state. The main difference between Grade 2 and Grade 1 is the annealing temperature. The minimum annealing temperature for Grade 1 is 1600°F (871°C), while the minimum annealing temperature for Grade 2 is 2000°F (1093°C).
