AMS 5529 specification covers a corrosion-resistant steel in the form of sheet and strip 0.0015 to 0.100 inch (0.038 to 2.54 mm) in nominal thickness in the solution heat-treated and cold-rolled condition. Precipitation Hardenable.

17-7PH or UNS S17700 alloy is typically used where a combination of strength and corrosion resistance is required in applications with service temperatures up to 600 deg F and the component part requires some ductility for additional forming and also increased strength from cold rolling.

17-7PH Material is supplied in the solution treated and cold worked condition. To assure the results of the final precipitation hardening treatment of component parts; samples of the product are tensile tested to specified minimum requirements in the as-shipped and after an age hardening heat treatment.

Heat Treatment and Processing

17-7PH is supplied in the solution heat-treated and cold-rolled condition (Condition C). To assure the results of the final precipitation hardening treatment of component parts, samples of the product are tensile tested to specified minimum requirements in both the as-shipped and after an age hardening heat treatment.

Common Heat Treatment Conditions:

Condition	Heat Treatment	Application
Cond A	Solution treated	Maximum formability
Cond C	Solution treated + cold rolled (AMS 5529)	As-supplied, high strength
TH1050	Conditioned + aged at 1050°F	Balanced strength and ductility
RH950	Conditioned + aged at 950°F	Maximum strength
CH900	Cold rolled + aged at 900°F	Highest strength (AMS 5529)

The material's minimal distortion upon heat treatment is a critical advantage for precision components that must maintain tight dimensional tolerances.

Whether you require 17-7PH strip for aircraft springs, surgical instruments, or high-performance fasteners, ZYTC Alloy provides certified materials with full traceability and technical support to meet your specific requirements.
