Product Overview


Product Description

Alloy 17-4PH (UNS S17400), Type 630, is a chromium-nickel-copper precipitation-hardening martensitic stainless steel with an addition of niobium. 17-4PH combines high strength and hardness with good corrosion resistance. The alloy is furnished in the solution annealed condition (Condition A). It should not be used at temperatures above 572°F (300°C) or for cryogenic service. Optimal mechanical properties can be obtained by subjecting the alloy to age hardening heat treatments. Heat treatment in the 900°F (482°C) range produces the highest strength. The corrosion resistance of Alloy 17-4PH is comparable to 304 stainless steel in most environments, and is generally superior to the 400 series stainless steels. It is used in applications where the combination of moderate corrosion resistance and unusually high strength are required. Alloy 17-4PH can be easily welded and processed by standard shop fabrication practices. It is magnetic.
17-4PH alloy features excellent corrosion resistance, superior to any other hardenable stainless steel. In most cases, it has as good corrosion resistance as type 304. Despite this, stress corrosion can happen under a high-strength state; if there is a risk of stress corrosion cracking, it will be necessary to adjust the stabilization temperature. The alloy 17-4PH is susceptible to corrosion or crack corrosion in static seawater. However, in the petrochemical, food processing and paper industries, its corrosion resistance matches grade 304L.
