Corrosion Resistance:


  • Alloy 17-4 PH withstands corrosive attacks better than any of the standard hardenable stainless steels and is comparable to Alloy 304 in most media
  • If there are potential risks of stress corrosion cracking, the higher aging temperatures then must be selected over 1022°F (550°C), preferably 1094°F (590°C). 1022°F (550°C) is the optimum tempering temperature in chloride media
  • 1094°F (590°C) is the optimum tempering temperature in H2S media
  • The alloy is subject to crevice or pitting attack if exposed to stagnant seawater for any length of time
  • It is corrosion resistant in some chemical, petroleum, paper, dairy and food processing industries (equivalent to 304L grade)
