product description of 17-4PH stainless steel bar

Huaxiao Stainless Steel Bar Supplier

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.
