Regular audits and a culture of continuous improvement ensure that our components are consistently manufactured to the most exacting standards.
17-4 PH (also written 17/4PH, 17-4 stainless steel, or Type 630) is a precipitation-hardening martensitic stainless steel known for its excellent combination of high strength, hardness, and corrosion resistance.
17-4 PH stainless steel is produced in a wide range of physical forms depending on how it’s going to be used.
You can find it as bars, rods, plates, sheets, strips, forgings, and castings, and even as powder for additive manufacturing (3D printing).
The term “PH” stands for precipitation hardening, which is how the material gains its strength. After being solution treated (called Condition A), 17-4 PH can be aged at various temperatures to achieve different combinations of strength and toughness.
Each heat treatment condition is given a code, such as H900 or H1150.
