The high molybdenum content and high chromium and nitrogen content make UNSS31254 extremely resistant to pitting and crevice corrosion. The addition of copper improves the corrosion resistance in some acids. In addition, due to its high nickel content and high chromium and molybdenum content, UNSS 31254 has a very good resistance to stress corrosion cracking.
