DIPTI METAL INDUSTRIES
Alloy 20 (UNS N08020) Round Bar Manufacturer & Alloy 20 Exporter | Carpenter 20 Rods
Dipti Metal Industries is a premier Alloy 20 Manufacturer and Supplier of Alloy 20 (UNS N08020) Bars and Rods based in Mumbai, India. Often referred to as Carpenter 20® or Cb-3®, this austenitic nickel-iron-chromium alloy is specifically developed for maximum resistance to acid attack, particularly sulfuric acid.
We produce Alloy 20 Round Bars in india, Alloy 20 Hex Rods in mumbai, and Alloy 20 Square Bars exporter to ASTM B473 standards. With Niobium stabilization, our Alloy 20 bars offer excellent resistance to intergranular corrosion, making them the material of choice for chemical mixing tanks, pickling racks, and pharmaceutical piping systems.
Why Choose Dipti Metal for Alloy 20 Bars?
Alloy 20 bridges the gap between stainless steels and high-nickel alloys. It contains Copper (3-4%) and Molybdenum (2-3%) to provide superior resistance to pitting and chloride-ion stress corrosion cracking. The addition of Niobium (Nb) minimizes carbide precipitation during welding.
We stock and manufacture Alloy 20 bars that are widely used in the production of gasoline, solvents, explosives, inorganic chemicals, and synthetic rubber.
