Detail

NS112

Materialgrade: NS112 corrosion resistant alloy

US grade: UNS N08811

German grade: W,Nr,1,4876

I,overview:

NS112 (N08811, 1,4876) is a full austeniticlow carbon nickel-iron-chromium alloy in the same series as Incoloy 800, Thecobalt content of this alloy can be strictly controlled below 0,01%. NS112 isresistant to many corrosive media. Its high nickel content gives it excellentresistance to stress corrosion cracking in aqueous corrosion conditions. Thehigh chromium content gives it better resistance to pitting and crevicecorrosion cracking. The alloy has good resistance to nitric acid and organicacid corrosion, but has limited corrosion resistance in sulfuric acid andhydrochloric acid. In addition to pitting corrosion in halides, it has goodcorrosion resistance in oxidizing and non-oxidizing salts. It also has goodcorrosion resistance in water, steam and a mixture of steam, air and carbondioxide. Used in nitric acid condensers - resistant to nitric acid corrosion,steam heating tubes - good Mechanical properties, heating element tubes - goodMechanical properties. For applications up to 500 ° C, the alloy state isannealed.

1, NS112 (N08811,1,4876) corrosion resistant alloy has the following characteristics:

(1) Excellent corrosion resistance in anextremely high temperature aqueous medium up to 500 °C,

(2) Good resistance to stress corrosion,

(3) very good processability,
