17-4PH stainless steel offers superior corrosion resistance compared to standard hardenable stainless steels, performing comparably to Alloy 304 in most environments. For applications with stress corrosion cracking risks, aging temperatures above 1022°F (550°C) are recommended.
Note: The alloy may experience crevice or pitting corrosion when exposed to stagnant seawater for extended periods.
