UNS N08020

Nickel Alloy UNS N08020 flanges are high-performance materials engineered for extreme durability and corrosion resistance. This unique alloy, often called Alloy 20, owes its unique blend of properties to an intricate chemical composition. It is predominantly composed of nickel (around 35% to 38%) combined with chromium in the range of 19% to 21%, responsible for its exceptional resistance to oxidising or reducing environments. The addition of approximately 32.5% to 35% iron confers strength and further enhances corrosion resistance. Besides these primary constituents, the alloy manifests other crucial elements, such as molybdenum (2% to 3%) and copper (3% to 4%), to resist pitting and crevice corrosion, while columbium, tantalum and carbon (less than 1% collectively) act as stabilising and intergranular corrosion-inhibiting agents. This complex mixture culminates in an alloy known for its impressive adaptability in diverse applications, including chemical processing, petrochemical, and power generation industries.

Nickel Alloy UNS N08020 Flanges boast remarkable attributes, making them the material of choice for many demanding applications. Exhibiting exceptional resistance to corrosion and oxidation, these flanges are particularly useful in challenging environments of the chemical and petrochemical industries. Their unique composition encompasses a mix of chromium, molybdenum, and copper, ensuring the flanges maintain excellent mechanical properties even at elevated temperatures. Additionally, the presence of niobium in the alloy contributes to their stabilisation and superior welding characteristics. With such high-performance features, Nickel Alloy UNS N08020 Flanges are undeniably valuable in constructing equipment destined for harsh operating conditions, providing a reliable and long-lasting solution.
