Alloy 20 is an austenitic, nickel-iron-chromium based super alloy with additions of Copper and Molybdenum which provide resistance to hostile environments, pitting, and crevice corrosion.

The chemical composition of Alloy 20 pipes is as follows

·                   Nickel, 32.5–35%

·                   Chromium, 19–21%

·                   Carbon,0.06% maximum

·                   Copper, 3–4%

·                   Molybdenum, 2–3%

·                   Manganese, 2% maximum

·                   Silicon, 1% maximum

·                   Niobium, (8.0 X C), 1% maximum

·                   Iron, 31–44% (balance)
