DESCRIPTION:
Alloy 17-4PH withstands corrosive attacks better than any of the standard hardenable stainless steels and is comparable to type 304 in most media.
Alloy 17-4PH withstands corrosive attacks better than any of the standard hardenable stainless steels and is comparable to type 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.
DESIGN FEATURES:
The following physical properties have been obtained after hardening 896°F (480°C) – 1 hour - air cooling
