What is AMS 5528 in 17-7 Stainless Steel?

AMS 5528 is an aerospace material specification for a corrosion resistant precipitation
hardenable steel alloy. Common names for the alloy are 17-7 or UNS S17700.
AMS 5528 material is in the form of sheet, strip, or plate.
This 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
ductility for forming.
Material to this standard is supplied in the solution heat treated condition that can be readily
heat treated to final properties after component forming during the manufacture of component
parts.
To assure the results of the final precipitation hardening treatment; samples of the product are
heat treated to specified minimum requirements.
