Stainless 17-4 PH Type 17-4 PH stainless steel is the most widely used of all of the precipitation-hardening stainless steels. Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. Type 17-4 PH is a martensitic precipitation-hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, and good mechanical properties at temperatures up to 600°F (316°C). Its unique combination of properties make this alloy an effective solution to many design and production problems. Chemical Composition, % Resistance to Corrosion: Type 17-4 PH 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. Features • Excellent resistance to corrosion • Provide toughness in both base metals and welds. • Well suited to applications that require ease of fabrication and then the addition of strength/hardness for improved reliability Aerospace applications Chemical processing equipment Oil and petroleum refining equipment Food processing equipment General metalworking
