Type 17-4PH is a martensitic precipitation-hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties at temperatures up to 600 °F (316 °C), good toughness in both base metal and welds, and short time, low-temperature heat treatments that minimize warpage and scaling.
Also known as Alloy 630, type 17-4PH is the most widely used of all precipitation-hardening steels. Compared to other PH alloys, it requires a simple heat treatment to produce a wide range of properties, including its high strength. It has a slightly higher ferrite content than other PH grades, making it a bit more magnetic. To improve formability, heat treatments may be used before cold working.
We are suppliers of 17-4 PH stainless steel sheet and coil,Strips, strip coil, in addition to stocking 17-4 PH round bar and plate. Our materials can be found in aerospace applications, gas turbines, chemical processing equipment, oil refining equipment, food processing industries and more.
