Full title and description
SAE AMS2759/1J — Heat Treatment of Carbon and Low-Alloy Steel Parts: Minimum Tensile Strength Below 220 ksi (1517 MPa). This material specification establishes heat‑treatment requirements for carbon and low‑alloy steel parts where the required minimum ultimate tensile strength is below 220 ksi (1517 MPa), and it is intended to be used together with the general requirements of AMS2759.
Abstract
AMS2759/1J (Revision J, 2021) defines procedures, acceptance tests and limitations (including size limits related to limited hardenability) for quench-and‑tempering and other heat treatments of specified carbon and low‑alloy steels to achieve minimum tensile strengths under 220 ksi. Revision J includes clarifications on surface contamination, periodic testing for certain part types, separation of hardness and surface‑contamination acceptance tests, and table corrections for specific alloys.

Scope
This specification, used together with AMS2759 (general steel heat‑treatment requirements), applies to the heat treatment of carbon and low‑alloy steel parts where the minimum ultimate tensile strength requirement is below 220 ksi (1517 MPa). It includes process controls, acceptance testing (hardness and surface contamination), size‑limit considerations because of limited hardenability, and alloy‑specific provisions. The document is intended for aerospace and other applications where AMS material specifications are invoked.
Key topics and requirements
- Defined heat‑treatment procedures (quench, temper, and related cycles) and process controls for carbon and low‑alloy steels.
- Minimum ultimate tensile strength threshold: parts covered are those below 220 ksi (1517 MPa).
- Size limitations due to limited hardenability of listed alloys; alloy‑specific allowances and restrictions.
- Acceptance tests, including hardness checks and surface‑contamination criteria; Revision J separates hardness and surface‑contamination acceptance requirements.
- Periodic testing and inspection requirements for certain part types (clarified in Revision J).
- Tables identifying alloys and corrected alloy listings introduced in Revision J (table corrections and additions).
Typical use and users
This AMS specification is used by aerospace manufacturers, heat‑treat service providers, inspection laboratories, and procurement/quality engineers who require or perform heat treatment of carbon and low‑alloy steel components to AMS material requirements specified on drawings or purchase orders. Typical applications include structural and high‑strength parts where controlled tensile properties and heat‑treatment traceability are required.
Related standards
Related documents include the parent AMS2759 (general requirements for heat treatment of steel parts) and other AMS2759 sub‑documents covering different material classes and processes (for example AMS2759/2, AMS2759/3, etc.). The AMS2759/1 series (previous revisions A–I) are the historical predecessors leading to Revision J. Users should reference AMS2759 for overarching process and documentation requirements.
