Inconel UNS N06625 Fine polishing Metal Plate
Inconel 625 fine polishing plate is a high-performance nickel-chromium-molybdenum-niobium alloy material treated by a special process. It obtains an ultra-smooth surface (Ra≤0.1μm) through precision polishing. The material is based on nickel (≥58%), with 21-23% chromium, 8-10% molybdenum and 3.15-4.15% niobium added, forming a unique dual mechanism of solid solution strengthening and precipitation strengthening, which makes it have ultra-high strength of 690-1100MPa and excellent elongation of 30-45%. Fine polishing not only gives it a mirror-like smooth appearance, but also significantly improves the surface density and effectively reduces the tendency of pitting in corrosive media.
The alloy performs well in extreme environments: the oxidation resistance temperature can reach 982℃, and it shows extraordinary corrosion resistance in seawater and acidic media (including hydrochloric acid, sulfuric acid, etc.), especially resistant to stress corrosion cracking caused by chlorides. Its unique molybdenum-niobium synergistic effect also gives the material excellent fatigue resistance and creep resistance, and maintains stable mechanical properties at a high temperature of 650℃. Fine polished surfaces are particularly suitable for ultra-high clean environment requirements and can minimize particle contamination and medium adhesion.
Main application areas include:
Aerospace (engine tail nozzle, combustion chamber components)
Marine engineering (subsea equipment, seawater treatment system)
Chemical equipment (pickling equipment, reactor lining)
Nuclear industry (nuclear fuel post-processing components)
Semiconductor (ultra-high vacuum chamber, wafer processing equipment)
It is the preferred material for harsh working conditions that require ultra-high strength, extreme corrosion resistance and surface cleanliness at the same time, and is particularly suitable for high-end industrial applications that require both mechanical properties and ultra-smooth surfaces.
