Stainless steel 17-4 PH is a type of martensitic precipitation-hardening stainless steel. It is composed of about 17% chromium, 4% nickel, and 4% copper. This combination of elements gives the material excellent corrosion resistance, as well as high strength and hardness. It is commonly used in applications that require high strength and corrosion resistance, such as aerospace and defense components, and oil and gas industry parts. It can be heat treated to achieve a range of mechanical properties, making it a versatile material.
