Full title and description

SAE AMS2759G — Heat Treatment of Steel Parts: General Requirements. This aerospace material specification from SAE International (Revision G, published April 23, 2019) establishes the general requirements, ordering instructions, process controls and test/inspection requirements that apply to heat treatment of steel parts when specified by a purchaser or user.

Abstract

AMS2759G provides the baseline, general requirements for the suite of AMS2759 heat-treatment specifications. It covers procedural and quality elements that apply across the AMS2759 family (e.g., parts definition, process controls, test specimen requirements, handling of surface contamination, documentation and traceability). Revision G corrected items such as part-type descriptions, test-specimen hardenability details and surface-contamination language while deleting certain quench-media control language and consolidating notes on soaking start.

General information

• Status: Revised (Revision G).
• Publication date: April 23, 2019.
• Publisher: SAE International (Society of Automotive Engineers).
• ICS / categories: Heat treatment; Manufacturing engineering; Aerospace materials (ICS: heat treatment — 25.200; surface treatment / aerospace — 49.040).
• Edition / version: AMS2759G (Revision G, 2019).
• Number of pages: 16 pages (AMS2759G document).

Scope

AMS2759G establishes the general requirements applicable to the heat treatment of steel parts performed by a user, vendor or subcontractor when the purchaser specifies AMS2759 as the governing general-requirements document. It defines processes referenced in the AMS2759 family, identifies required records and tests, and supplies ordering instructions and acceptance criteria that apply across the series of steel heat-treatment specifications.

Key topics and requirements

• General ordering instructions and purchaser-supplier responsibilities for steel-part heat treatment.
• Process controls and allowed/required heat-treatment operations (hardening, tempering, annealing, stress relief, etc.).
• Requirements for test specimens, hardenability testing and tensile-strength classification.
• Surface contamination and part handling controls to protect heat-treatment outcomes (cleaning, masking, segregation and inspection).
• Documentation, traceability, lot records, and inspection/test acceptance criteria.
• Revision G technical corrections: updates to part-type descriptions, test-specimen hardenability details and surface-contamination language; deletion of one quench-media control clause; movement of soaking-start guidance from a note into the body.

Typical use and users

AMS2759G is used by aerospace and defense OEMs and their supply chains, independent heat-treat shops, quality/inspection personnel, purchasing and procurement teams, metallurgists and engineering departments that specify, perform or verify heat-treatment processes on steel parts. It is referenced wherever AMS-type heat-treatment procedures and uniform requirements are needed for flight-critical or high-reliability components.

Related standards

AMS2759G is the general-requirements document for the AMS2759 family and is used together with the part-/alloy-specific AMS2759/x specifications (for carbon and low-alloy steels, precipitation-hardened steels, corrosion-resistant steels, etc.). It is commonly applied alongside pyrometry and furnace-control standards such as AMS2750 (pyrometry / furnace temperature control and uniformity) to ensure equipment and process capability.

FAQ

Q: What is this standard?

A: AMS2759G is an SAE International aerospace material specification titled "Heat Treatment of Steel Parts — General Requirements" (Revision G), which sets out the general requirements and ordering instructions for heat-treating steel parts.

Q: What does it cover?

A: It covers general procedural, quality, testing and documentation requirements that apply across the AMS2759 family of heat-treatment specifications for steel parts (e.g., test specimens, hardenability, surface contamination controls, records and acceptance criteria). Revision G made several technical corrections to these general requirements.

Q: Who typically uses it?

A: Aerospace and defense manufacturers, OEMs, subcontract heat-treaters, metallurgical engineers, quality/inspection teams and procurement organizations that require consistent, auditable heat-treatment practices for steel parts.

Q: Is it current or superseded?

A: Revision G (AMS2759G), published April 23, 2019, is the published Revision G document. Consult SAE International (SAE Mobilus or the SAE standards store) for any later amendments or subsequent revisions beyond Revision G; AMS2759G is the revision shown in SAE's public record for this product.

Q: Is it part of a series?

A: Yes — AMS2759G is the general-requirements (parent) document for the AMS2759 series. Alloy- and treatment-specific documents (for carbon/low-alloy steels, corrosion-resistant steels, precipitation-hardening steels, stress-relief procedures, etc.) are published as AMS2759/1, AMS2759/3, AMS2759/5, AMS2759/11, and related parts. These companion documents contain the detailed, alloy-specific processing requirements used together with AMS2759G.

Q: What are the key keywords?

A: Heat treatment, steel parts, AMS2759G, SAE, hardening, tempering, annealing, quench, hardenability, pyrometry, traceability, surface contamination, aerospace material specification.
