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.
17-4PH is a martensitic precipitation hardening stainless steel. The performance characteristics of 17-4PH are that it is easy to adjust the strength level, which can be adjusted by changing the heat treatment process. Martensitic transformation and aging treatment to form precipitation hardening phase are the main strengthening means, 17-4PH has good attenuation performance, strong corrosion fatigue resistance and water drop resistance. It can meet the requirements of high temperature resistance and strong tensile strength, because its chemical composition contains aluminum precipitation hardening element. The characteristics of the product are that it has stable elasticity and the strongest tensile strength, and its fatigue resistance is the strongest in the stainless steel series. ,hanger.
17-7PH Features: 17-4PH 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.
17-7PH stainless steel strip is a high-strength material with high elasticity and fatigue resistance. It is the preferred material for spring sheets. The production thickness is 0.1-6.0mm, the width can be slit, and the edge is deburred. The operating temperature is below 400 degrees.

17-7PH Material Application Areas

Aerospace industry, chemical and food processing equipment, oil refining equipment and general metalworking.
