Stainless Steel 17-4PH Forgings are martensitic precipitation-hardening alloys with 16–17.5% chromium, 3–5% nickel, 3–5% copper, and 0.15–0.45% niobium, balance iron and trace elements. These forgings provide top-class mechanical performance, which includes tensile strengths of up to 1310 MPa, yield strengths of close to 1170 MPa, and elongation of 10–15%, depending on heat treatment (H900–H1150). With hardness of up to 40 HRC, they retain toughness with corrosion resistance higher than regular martensitic grades. This strength-to-weight ratio coupled with hardness and versatility makes 17-4PH a very suitable option for high-performance structural and precision engineering applications in corrosive and severe environments.

The ideal temperature range for forging Stainless Steel 17-4PH is 1850°F to 2050°F (1010°C to 1120°C). Post-forging, annealing or solution treating is necessary to achieve optimal properties.
Yes, Stainless Steel 17-4PH forgings can be forged into custom shapes. This alloy offers excellent strength, corrosion resistance, and machinability, making it suitable for precision custom forging applications.
The forging process for Stainless Steel 17-4PH typically takes several hours, including heating, shaping, and cooling. The exact duration depends on part size, complexity, and specific forging techniques used.
Stainless Steel 17-4PH Forgings are extensively used in industries where high impact toughness, corrosion resistance, and strength are essential. In the aerospace industry, they find use in landing gear components, turbine blades, shafts, and structural fittings. In the chemical and petroleum industries, they are utilized in pumps, pressure vessels, and valves that are subject to corrosive substances. They find use in marine applications as well, namely structural parts, propeller shafts, and equipment subjected to seawater. Their strength, hardness, and resistance to corrosion also make them suitable for tooling, instrumentation, and precision engineering in severe operating conditions. 17-4PH forgings provide reliable performance and long life in service, even at the most adverse conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
