Alloy 20 Strip | UNS N08020
Alloy 20 strip is mainly composed of three different elements including chromium, iron, and nickel. With these elements, the strip alloy is guaranteed to have strong corrosion resistance for applications where nitric, sulfuric, and other acids are present.
These strips also have strong stress-corrosion cracking resistance especially for environments where chloride is present.
Additionally, strip alloy 20 is weldable and easy to fabricate using the most conventional process. During these processes, the strip alloy 20 is capable of maintaining crevice and pitting resistance.
