17-7PH material properties

17-7PH is an austenitic-martensitic precipitation hardening stainless steel developed on the basis of 18-8CrNi, also known as controlled phase transformation stainless steel. 17-7PH stainless steel has unstable austenite structure after solution treatment, with good plastic toughness and workability. , most of the structure is transformed into low-carbon tempered martensite with good toughness, which is the state of use of steel and has good mechanical properties at medium temperature. 17-7PH corrosion resistance is better than general martensitic stainless steel.17-7PH Features: 17-7PH stainless steel has good mechanical properties, and the products are mainly used in many industries such as chemical industry, shaft, valve, shipbuilding, and chemical fiber.
