17-4 is typically supplied in Condition A, and can be heat treated at a variety of temperatures and times to achieve a wide range of properties.
The corrosion resistance of 17-4 PH is comparable to that of Type 304 stainless Steel in most media and superior to that of the hardenable 400 series stainless steels. The alloy exposed to seacoast atmosphere will gradually develop overall light rusting and pitting in all heat-treated conditions. In common with other stainless steels, 17-4 material is subject to crevice attack if exposed to stagnant seawater for any length of time.
