17-4PH stainless steel bar is a martensitic stainless steel precipitation hardened by copper and niobium. The mechanical properties of this stainless steel are significantly improved after heat treatment, and the compressive strength can reach 1100-1300 MPa (160-190 ksi). However, it cannot be used above 300°C (572°F) or at very low temperatures. The material has good corrosion resistance to atmospheric conditions, dilute acids or salts, and its corrosion performance is comparable to that of 304 and 430.
In addition, 17-4PH is a martensitic precipitation-hardening stainless steel with easily adjustable strength levels. The main means of strengthening is martensitic transformation and aging treatment to form precipitation hardening phase. This stainless steel has good resistance to corrosion fatigue and fracture resistance.
In industrial applications, 17-4PH is used in the manufacture of shafts, turbine components and so on.

Features Of 17-4PH Stainless Steel Bar
In addition to its high strength and excellent corrosion resistance, 17-4PH stainless steel bar has the following key features:
- Good machinability and weldability: 17-4PH stainless steel can be easily machined and welded operations, which makes it highly productive in the manufacturing process.
- Heat and oxidation resistance: 17-4PH stainless steel can maintain good properties over a range of temperatures while also resisting oxidation. This makes it better suited for certain high temperature applications.
- Good corrosion resistance: 17-4PH stainless steel has good corrosion resistance to atmospheric conditions, dilute acids or salts, etc. This allows it to maintain good stability and durability in many corrosive environments.
- Precipitation hardening: Through aging treatment, 17-4PH stainless steel can obtain higher strength and hardness, and also improve its corrosion fatigue and fracture resistance.
- Beautiful luster: chromium is one of the main components in 17-4PH stainless steel, which gives this stainless steel a unique luster and makes it highly attractive in appearance.
In conclusion, 17-4PH stainless steel bar is a kind of stainless steel material with excellent comprehensive performance, which is suitable for a variety of different applications.
