Nickel Alloy 20, UNS N08020 is an austenitic metal primarily comprised of nickel, iron, and chromium. It was originally developed to fill an industrial need for elite resistance to acidic substances, and alloy 20 is particularly adept at resisting the damaging effects of sulfuric acid. Sometimes classified as a "super alloy," alloy 20 also displays strong mechanical properties and is relatively easy to machine and fabricate.
Alloy 20 is an iron-base, austenitic alloy with excellent corrosion resistance to a number of different media and proves to be useful in a number of applications such as flue-gas desulfurization, chemical processing, food processing and storage as well as pharmaceutical applications to name a few. Application of the alloy could result in real cost savings when carefully compared to higher-cost alloys to determine if the necessary resistance is obtained in the chosen media. Applications are limited to a maximum temperature of 1000°F per ASME.
Resistance to sulfuric acid is particularly exceptional but the alloy shows useful resistance in phosphoric acid, nitric acid as well as in chloride environments. Alloy 20 is an excellent option when chloride stress corrosion cracking is an issue and resists pitting and crevice corrosion.
Alloy 20 can be formed by either hot-working or cold-work using traditional methods. Hot forged material should be heated between 2100°F and 2250°F with careful temperature control insuring that the material not fall below 1800°F prior to forging. After hot working, anneal the material by heating to 1725°F and 1850°F for a minimum of 30 minutes per inch of thickness followed by water quench.
When stress relieving is desired, heat to a temperature below 1000°F followed by water quench after the desired time at temperature
has been established. Annealing Alloy 20 should be between 1725°F and 1850°F for 30 minutes at temperature per inch of thickness. A lower hardness can be obtained by heating to 2100°F but his may have a negative effect on the stabilization of the alloy.
Welding Alloy 20 is commonly performed via, TIG, MIG as well as submerged arc welding (SAW) using either the matching filler metal, ER320LR for TIG and MIG and E320LR for SAW. When welding to dissimilar alloys such as 316 or higher alloys such as C276 and Alloy 22, AWS ERNiCrMo-3 can be used for TIG and MIG while using ENiCrMo-3 for SAW.
