How does Alloy 20 get its resistance to corrosion?

The main reason why Alloy 20 makes use of molybdenum, chromium, nickel and copper is linked to its application, mainly the chemical industry. For this reason, the alloy has to be resistant in front of the action of acids, in front of general corrosion, crevice corrosion and pitting.

More than that, given that the chemical reaction that usually take place in a chemical plant involve oxidization, an alloy able to withstand its effects is a priority. Acids like sulfuric acid, nitric acid and phosphoric acid can easily take their toll on surfaces, so a good alloy, like the one on this link, has to be used.
