17-4PH | 1.4548 - Data sheet
1.4548.4 | UNS S17400 | AMS 5622 | AMS 5643 | WL 1.4548.4 | 1.4548.9
The high alloy steel 17-4PH is one of the most commonly used precipitation hardened stainless steels. It contains about 17% chromium and 4% nickel with additions of copper. This type of steel has a martensitic crystalline structure in combination with a very hard and brittle structure that is due to stabilization via precipitation heat treatment. The corrosion resistance of 17-4PH is comparable to that of 304 stainless steel in most media. An excellent combination of high strength and good corrosion resistance at temperatures up to 316°C make this stainless steel extremely versatile and an effective solution for many applications.
