ASTM B407 alloy seamless pipe has a higher nickel content that makes it resistant to stress corrosion cracking in water-borne corrosion conditions. The higher chromium content makes it more resistant to pitting and crevice corrosion cracking. This material has good corrosion resistance to nitric acid and organic acids, but limited corrosion resistance to sulfuric acid and hydrochloric acid. It has excellent corrosion resistance in oxidizing and non-oxidizing salts, and there is a possibility of pitting in halides. It also has excellent corrosion resistance in water, steam, and mixtures of steam, air, and carbon dioxide.
