Composition and application

Alloy Incoloy 20 (alloy 20, 2.4660) belongs to the group of low-carbon austenitic alloys based on iron, nickel and chromium, which are stabilized by niobium, and additionally doped with molybdenum and copper.

The alloy is highly chemical resistant against the effects of aqueous solutions of sulfuric, nitric and phosphoric acids and excellent resistance to intergranular corrosion. A special operational property of the alloy is the resistance to impact corrosion in chloride-containing media, which causes extensive use of the material for the manufacture of moving parts of marine high-speed vessels.

Alloy 20 also has excellent thermal resistance to general, slit and pitting corrosion. Due to the stabilizing action of niobium in the alloy of the grade Incoloy 20 (alloy 20, 2.4660), anticorrosion characteristics with increased mechanical properties and molding convenience are successfully combined. Therefore, alloy 20 is a popular choice for a wide range of industries, including the chemical, food, pharmaceutical and plastics industries. In addition, this alloy is used in heat exchangers, mixing tanks, equipment for metal cleaning and etching, as well as in various pipelines.

Many believe that the alloy Incoloy 20 (alloy 20, 2.4660) should be attributed to stainless steels, because the content of nickel and iron in it is on the acceptable boundary.

The chemical composition of the alloy, which is determined by the technical standards of ASTM A265 and UNS N08020, is given in the table (numeric data — in percent):

Ni Fe Cr Cu Mo Nb
32.00… 38.00 The basis 19.0… 21.0 3.0… 4.0 2.0… 3.0 Not more than 1,0
