High strength is maintained to approximately 600°F (316°C). This material has good resistance to stress corrosion cracking in the lower strength conditions.

Stainless Steel 17-4 PH Plates & Sheets is prized for its ability to simplify fabrication and manufacturing processes, which can result in significant cost savings and reductions. Engineers all over the world rely on this PH stainless steel as a solution to pressing logistical problems in Product Design, Manufacturing and Processing.

Alloy 17-4PH :

Alloy 17-4PH is a precipitation hardening martensitic stainless steel with Cu and Nb / Cb additions. The grade combines high strength, hardness (up to 572°F /300°C), and corrosion resistance. Mechanical properties can be optimized with heat treatment. Very high yield strength up to 1100-1300 MPa (160-190 ksi) can be achieved.

Alloy 17-4PH (UNS S17400), W. Nr. 1.4542 Type 630 is A Precipitation-Hardening Martensitic Stainless with High Strength and Hardness and Good Corrosion Resistance. The 17-4 stainless steel grade is an age-hardening martensitic alloy that combines high corrosion resistance and strength. Unlike conventional martensitic steels, it weldable by all standard methods, and achieves hardening with simple low-temperature treatment over a short period of time. This product is a cost-effective replacement for high strength carbon steels as well as other stainless grades as it has a high strength and resistant to corrosion.

General Properties of Stainless Steel Alloy 17-4 PH :

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.

New Arise Metal stocks 17-4 PH Stainless Steel. 17-4 PH is a chromium-nickel grade of stainless that may be hardened by a single low temperature precipitation-hardening heat treatment. Excellent mechanical properties at a high strength level may be obtained by such treatment. Scaling and distortion is minimized. 17-4 PH should not be used in the solution treated condition.  17-4 machines well, has excellent welding characteristics, and forges easily. The combination of good mechanical and processing properties makes this grade adaptable to a wide range of uses. Alloy 17-4 PH withstands corrosive attacks better than any of the standard hardenable stainless steels and is comparable to Alloy 304 in most media.

17-4PH Physical Properties :

Melting Range: 2560-2625°F (1404-1440°C)

Density: 0.2820 lb/in³

Features :

Corrosion Resistance: 17-4 stainless stands up excellently in a range of atmospheric environments even when exposed to corrosive elements.

Heat Resistance: Continuous use of 17-4 above 590⁰C is not recommended.

Temperature above can cause corrosive cracking. 550°C is the optimum tempering temperature in chloride media.

Very high yield strength up to 1100-1300 MPa (160-190 ksi) can be achieved.

Corrosion Resistance :

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 has corrosion resistance comparable to 304L in some chemical, dairy, food, paper and petroleum applications.

Alloy 17-4PH in the solution-annealed condition (Condition A) should not generally be put in service. The alloy is subject to brittle fractures and more sensitive to chloride stress corrosion cracking than the aged material.

If risks of chloride stress corrosion cracking are present the higher aging temperatures should be selected over 1022°F (550°C), preferably 1094°F (590°C). 1022°F (550°C) is the recommended tempering temperature in chloride service. 1094°F (590°C) is preferred in H2S media.

Alloy 17-4PH is subject to crevice corrosion and pitting attack when exposed to stagnant seawater for duration of time.

Cold Forming :

Alloy 17-4PH has limited cold forming properties. Cold forming can only be undertaken on plates in the fully annealed condition. Stress corrosion resistance is enhanced by re-aging at the precipitation hardening temperature after cold working.

Hot Forming :

Heat uniformly at 1742 – 2192°F (950 – 1200°C). A full solution anneal, cooling lower than 76°F (25°C) and aging at the required temperature must occur after hot forming. The post forming heat treatment should be a function of the desired mechanical properties.

Machining :

Alloy 17-4PH can be machined in both the solution treated and precipitation hardened conditions. Machining characteristics may vary according to the hardness of the metal. High speed tools are acceptable, but carbide tools are preferred. Standard lubrication should be used. Dimensional changes as a result heat treatment should be taken into account if very stringent tolerances are required.

Cutting :

Thermal cutting operations such as plasma cutting should be avoided. Mechanical cutting operations such as bandsaw, abrasive waterjet, shearing and machining are preferred.

Welding :

Alloy 17-4PH can be readily welded by most standard processes including SMAW, GTAW, PAW and GMAW.
