Stainless Steel 17-4PH, also known as 630 stainless, is a precipitation-hardening martensitic alloy. Its composition is defined by a precise balance of chromium (around 17%) and nickel (about 4%), with the key addition of copper and niobium. This unique formula allows it to be heat-treated to achieve impressive mechanical properties. Through this process, it develops remarkably high tensile and yield strength, coupled with good toughness and resistance to corrosion, making it significantly stronger than standard austenitic stainless steels.

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.
The exceptional qualities of 17-4PH forgings make them indispensable across numerous demanding sectors. They are commonly found in aerospace components like landing gear parts and turbine engines, where strength and weight are critical. The oil and gas industry relies on them for valves, pump shafts, and other downhole tools that must withstand corrosive environments under high pressure. You’ll also find these durable forgings in automotive racing components, chemical processing equipment, and even within the medical field for certain surgical instruments, proving their versatility and reliability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
