17-4 PH stainless steel (also known as UNS S17400) is a precipitation-hardening martensitic stainless steel. It contains approximately 17–4% chromium, 4% nickel, and 7–8% copper. The copper content of the alloy makes it highly resistant to corrosion, but also makes it slightly more susceptible to stress corrosion cracking. The alloy can be further strengthened by heat treatment and age-hardening.

17-4 PH stainless steel is commonly used in applications that require high levels of strength and corrosion resistance, such as aircraft and aerospace parts, heat exchangers, fasteners, valves, and pumps. It is also often used in industries such as medical and food that require sanitary conditions. The alloy has a high level of formability, allowing it to be easily molded into complex shapes.

17-4 PH stainless steel can be heat treated to achieve a wide range of mechanical properties. Heat treatment is typically performed between 1100°F (593°C) and 1550°F (843°C). Heat treatment is often followed by a post-treatment process, such as annealing. This post-treatment process is used to enhance the stainless steel’s corrosion resistance and ductility.

17-4 PH stainless steel is composed primarily of iron, chromium, and nickel. It also contains other elements, including copper, manganese, silicon, aluminum, phosphorus, and sulfur. These elements give the alloy its unique properties, such as strength, corrosion resistance, and formability.
