What Is 17-4ph Stainless Steel? 17-4PH stainless steel is a high strength, corrosion resistant and ductile steel. 17-4PH stainless steel is an age-hardened steel that can be heat treated and cold worked to increase its strength and hardness. The material has good thermal stability and can work at high temperatures.

Advantages And Disadvantages Of 17-4PH Stainless Steel

 After appropriate treatment, it will eventually transform into a martensite structure and reach a high strength level. This steel has poor low-temperature toughness and becomes brittle below -100°C. The corrosion performance is better than that of general martensitic stainless steel.

Chemical properties: Oxidation resistance is similar to that of 18-8 austenitic stainless steel. The corrosion resistance is better than that of general martensitic stainless steel, between nickel-chromium austenite and martensitic stainless steel.

17-4PH stainless steel has the following advantages:

1. Good mechanical properties: In the annealed state, 17-4PH stainless steel has high strength and toughness and can be used to manufacture high-strength parts.
2. Good welding performance: 17-4PH stainless steel can be structurally welded by conventional welding methods without causing degradation of microstructure and properties.
3. Good dimensional stability of parts: 17-4PH stainless steel experiences smaller volume changes during the heat treatment process, so the parts are dimensionally stable after cnc machining 17-4ph stainless steel parts.
4. Excellent high-temperature stress relaxation performance: 17-4PH stainless steel has good high-temperature stress relaxation resistance, so it maintains good mechanical properties when exposed to high temperatures for a long time.
5. Good corrosion resistance: 17-4PH stainless steel contains elements such as chromium and nickel, and has good corrosion resistance in acid, alkali and other environments.
