Alloy 20 Tube, also known as Carpenter 20 Tube, is a nickel-iron-chromium austenitic alloy that was developed for maximum resistance to acid attack, specifically sulfuric acid. Alloy 20 Seamless Tube is also stabilized with Columbium to minimize carbide precipitation during welding. Alloy 20 Tubing is designated as UNS N08020 and Werkstoff Number 2.4660. Alloy 20 Seamless Tubing also known as CN7M Tubing, Carpenter 20 Tubing, CB-3 Tubing, AL 20 Tubing, Carlson Alloy C20 Tube, Nickelvac 23 Tube, Nicrofer 3620 Nb Tube and VDM® Alloy 20 Tubing.
