About 17-4PH(630) Stainless Steel
17-4 PH is a martensitic precipitation hardening stainless steel with additions of copper (Cu), niobium (Nb) and tantalum (Ta). The grade combines high strength and hardness values with moderate corrosion resistance. Different heat treatment temperatures can optimize mechanical properties, e.g. yield strength at 1100 – 1300MPa. Our stock material is double aged at 620°C (1150°F) – defined as H1150D.
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.
