Resistance to Corrosion
Type 17-4PH stainless steel has excellent resistance. It withstands corrosive attack better than any of the standard hardenable stainless steels and is comparable to Type 304 in most media.
This has been tested in a wide variety of corrosive conditions in the petrochemical, petroleum, paper, dairy and food processing industries, and in applications such as boat shafting. Additional proof of its durability is the replacement of chromium-nickel stainless steels and high-alloy non=ferrous metals by Type 17-4PH stainless steel for a broad range of parts requiring excellent resistance to corrosion.
