17 – 4 PH steel is a martensitic precipitation or age-hardening stainless steel that combines high strength and hardness with excellent corrosion resistance. It may be age hardened by a single- step low- temperature treatment.Alloy 17-4PH is a versatile precipitation-hardening steel showing excellent strength and corrosion-resisting characteristics. It is readily machinable, weldable and formable.


This grade of steel is used for a variety of applications including oil field valve parts, chemical process equipment, forged aircraft fittings, fasteners and pump shafts, gears, nuclear reactor parts and jet engine parts.


Forging of this grade should be carried out between 2150/2200 º F (1180/1200 º C) and 1850 º F (1010 º C.) For optimum grain size and mechanical properties, forgings should be air cooled to below 90 º F (32 º C) prior to further processing. Forgings must be solution treated prior to hardening.
