    Patent number: 4201575
    Abstract: An austenitic stainless corrosion resistant alloy consisting essentially in weight percent (w/o) of______________________________________ Broad-(w/o) Preferred-(w/o) ______________________________________ C 0.06 Max. 0.015-0.025 Mn 1.00 Max. 0.50 Max. Si 0.50 Max. 0.40 Max. P 0.03 Max. 0.03 Max. S 0.03 Max. 0.005 Max. Cr 22-26 23.5-24.5 Ni 32.5-37 32.5-34.5 Mo 5-6.7 5.5-6.2 Cu 1.0-4 3.0-3.5 B 0.005 Max. 0.0015-0.0035 Nb 1 Max. 0.15-0.25 N 0.4 Max.* 0.05 Max. Ce + La 0.4 Max.** 0.3 Max.** ______________________________________ *OR the limit of solubility. **Amount added as misch metal.The balance is iron and incidental impurities. The alloy is useful for the production of parts requiring good resistance to corrosion. It has good resistance to pitting and stress corrosion when exposed to chlorides and has good resistance to oxidizing media. The alloy is particularly useful as parts for fume scrubbers and in phosphoric acid plants.
