Full title and description
SAE AMS5528K — Steel, Corrosion-Resistant, Sheet, Strip, and Plate, 17Cr - 7.1Ni - 1.1Al (Alloy 17-7); solution heat treated, precipitation-hardenable. Revision K (issued May 17, 2024).
Abstract
This aerospace material specification defines the chemical, mechanical, dimensional and heat-treatment requirements for Alloy 17-7 (17Cr‑7.1Ni‑1.1Al) supplied in sheet, strip and plate forms in the solution heat‑treated, precipitation‑hardenable condition. It is intended to ensure consistent material properties and acceptance criteria for aerospace/industrial applications.

- Publication date: May 17, 2024 (AMS5528K revision).
- Publisher: SAE International (Society of Automotive Engineers).
- ICS / categories: Aerospace materials; metallic materials — precipitation‑hardening stainless steels; material specifications for aircraft components.
- Edition / version: AMS5528K (Revision K, 2024).
- Number of pages: 7 (AMS5528K document length as listed by the publisher).
Scope
The specification covers Alloy 17‑7 (composition approx. 17% Cr, ~7.1% Ni, ~1.1% Al) in the form of sheet, strip and plate with nominal thicknesses from 0.005 inch (0.13 mm) up to 1.000 inch (25.40 mm) in the solution heat‑treated condition. It defines required chemical composition limits, heat‑treat procedures (solution and precipitation hardening), mechanical property requirements, dimensional and finish conditions, and acceptance/testing criteria for aerospace use.
Key topics and requirements
- Chemical composition limits for Alloy 17‑7 (Cr, Ni, Al and residual elements) and required compositional analysis/verification.
- Heat treatment: solution heat treatment and precipitation (age) hardening schedules and allowable conditions for delivery.
- Mechanical properties: tensile strength, yield strength, elongation and hardness criteria for specified tempers/conditions.
- Form factors and dimensional limits: permitted thickness range, allowable tolerances, surface condition and finish.
- Quality, acceptance and testing: required material test reports (MTRs), tensile and hardness testing, microstructure/condition verification and any specified corrosion or nondestructive inspections.
- Traceability and certification: documentation and lot identification required for aerospace procurement and DFARS/traceability considerations where applicable.
Typical use and users
Commonly used by aerospace OEMs, aircraft component manufacturers, defense contractors, spring and fastener makers, and precision metal suppliers for applications requiring a corrosion‑resistant, precipitation‑hardenable stainless steel (springs, structural components, formed parts and precision sheet elements). Material distributors and industrial suppliers also reference AMS5528 when specifying 17‑7PH sheet and strip for aerospace and high‑performance industrial parts.
Related standards
Other AMS documents and specifications that commonly relate to 17‑7PH products and processing include AMS5529 (precipitation‑hardened 17‑7 variants to specific strength levels), AMS5678 (17‑7 spring‑temper wire), and other AMS heat‑treatment and product‑form specifications for precipitation‑hardenable stainless alloys. Users should cross‑check specific product forms (wire, strip, plate) against the applicable AMS documents for temper/strength requirements.
