Nickel Alloy 625 Seamless Tubing:
Nickel Alloy 625 Seamless Tubing uses nickel-chromium-molybdenum-niobium alloy (UNS N06625), which has excellent corrosion resistance, oxidation resistance and high temperature strength. The alloy can maintain excellent mechanical properties in extreme environments and is particularly suitable for marine, chemical, nuclear power and aviation fields. Its high nickel content gives it strong tolerance to a variety of acidic media (such as sulfuric acid, phosphoric acid, nitric acid, etc.) and chlorides, avoiding the risk of stress corrosion cracking.
The heat treatment state is generally solution treatment (Solution Annealed), which can provide a bright annealed surface to improve appearance and corrosion resistance. The processing method is seamless drawing to ensure smooth inner and outer walls, precise dimensions, and no weld defects. It is suitable for high-pressure and high-cleanliness fluid transmission systems. For packaging, moisture-proof and collision-proof wooden boxes or woven bags are usually used to ensure transportation safety and storage stability.
