NS113 、 NS1103

 Overview of NS113 (NS1103) corrosion-resistant alloy:

NS113 is a fully austenitic low-carbon nickel-iron-chromium alloy. The cobalt content in this alloy can be strictly controlled below 0.01%. Can withstand many corrosive media. Its higher nickel content makes it have good resistance to stress corrosion cracking in water-based corrosion conditions. The high chromium content makes it better resistant to pitting corrosion and crevice corrosion cracking. The alloy has good corrosion resistance to nitric acid and organic acids, but the corrosion resistance in sulfuric acid and hydrochloric acid is limited. In addition to the potential for pitting corrosion in halides, it has good corrosion resistance in oxidizing and non-oxidizing salts. It also has good corrosion resistance in water, steam and mixtures of steam, air and carbon dioxide.
