Alloy 17-4PH or UNS S17400 or type 630, is a chromium-nickel-copper precipitation-hardening martensitic Stainless Steel with an addition of niobium. 17-4PH is normally supplied in annealed condition,that is Condition A. This Alloy combines high strength with good corrosion resistance. Optimal mechanical properties can be obtained by age hardening heat treatments. 17-4PH can be easily welded and processed machining practices. The Alloy is magnetic.
Typical Applications
Aerospace, structural parts
Biomedical applications
Chemical processing
Food process equipment
Oil & Gas applications
General high strength applications
Nuclear Waste processing and storage

Industry Specifications
EN/DIN 1.4542/ X5CrNiCuNb16.4/ AFNOR Z6CNU17-O4/ ASME SA 693
Material may also be supplied against Customer specifications, subject to enquiry.
Chemical Analysis
Alloy 718 is hardened by the precipitation of secondary nickel- (aluminium, titanium, niobium) phases giving the alloy a combination of high strength and good corrosion resistance.

Mechanical Properties
Machinability
17-4PH can be machined in both conditions; means in solution annealed and aged conditions. Machining characteristics may vary according to the hardness. Hi speed tools are accepted, but carbide tools are preferred. Standard coolant should be used. Dimensional changes as a result of the heat treatment should be taken into account, if very stringent tolerances are required.
