ASTM b473 UNS n08020 Material in wide Sizes and Thickness at reasonable price  in Mumbai and Tamil Nadu

Alloy 20 Round Bars are 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 chemical processing, food processing, flue-gas desulfurization and storage as well as pharmaceutical applications to name a few. Application of the ASTM B473 Alloy 20 Bright Barcould result in real cost savings when carefully compared to higher-cost alloys to determine if the necessary resistance is obtained in the chosen media. The applications of alloy 20 bars are limited to a maximum temperature of 1000°F per ASME.

Resistance to sulfuric acid is brilliant but the alloy shows useful resistance in phosphoric acid, nitric acid as well as in chloride environments. ASTM B473 Alloy 20 Bright Baris an excellent option when chloride stress corrosion cracking is an issue and resists pitting and crevice corrosion.

Alloy 20 Rods can be formed by either hot-working or cold-work using traditional methods. Hot forged material is heated between 2100°F and 2250°F with careful temperature control. While doing that we make sure that the material should not fall below 1800°F prior to forging. After hot working, annealing the material it is heated upto1725°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 this may have a negative influence 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, Alloy DIN 2.4660 Hexagon Bars for TIG and MIG and E320LR for SAW. When welding to dissimilar alloys or higher alloys AWS ERNiCrMo-3 can be used for TIG and MIG while using ENiCrMo-3 for SAW.
