17-4 PH stainless steel can be used for a variety of industries including pump shafts, oil path, mechanical seals, and within the aerospace industry. Its composition is carbon, chromium, columbian + tantalum, copper, manganese, nickel, phosphorous, silicon, and sulfur.

Below you will find typical applications of 17-4 PH stainless steel as well as the metals composition and mechanical properties.

Typical usage is seen in applications requiring high strength and a modest level of corrosion resistance. Strength and toughness desired can be manipulated by temperate range in the heat treatment process.
