Overview

17-4PH is a very widely used precipitation hardened stainless steel alloy with a toughness especially suited for the aerospace, nuclear energy, and chemical processing industries.

This alloy features good corrosion resistance, hardness, toughness and strength. It is soft and ductile when solution annealed, yet can achieve high properties through precipitation or aging treatment.

These properties make it especially useful for aircraft engines, gears, fittings, fasteners, and valves. 17-4PH is also widely used in nuclear reactor components, paper mill equipment, and oil field parts.
 
We handle 17-4 PH in a wide variety of forms.
