Full title and description

SAE AMS-DTL-23053/6B (2018) — Aerospace Material Specification: Titanium Alloy, Strip, Cold-Rolled, Incrementally Formed, for Airframe and Engine Structural Applications. This detailed specification covers materials, heat treatment, manufacturing processes, chemical and mechanical property requirements, testing, marking and acceptance criteria for cold-rolled, incrementally formed titanium alloy strip used in critical aerospace structures and components.

Abstract

This specification establishes requirements for cold-rolled, incrementally formed titanium alloy strip intended for airframe and engine structural applications. It defines applicable alloys and tempers, chemical composition limits, mechanical property minima (tensile strength, yield strength, elongation), heat-treatment and processing controls, inspection and testing procedures (including hardness, tensile, microstructure and interstitial content testing), dimensional tolerances, surface quality, lot acceptance criteria and required markings and certification documentation for procurement and quality assurance.

Scope

This standard specifies the requirements for cold-rolled, incrementally formed titanium alloy strip intended for structural use in aircraft and engine components. It covers acceptable alloys and tempers, chemical composition limits, mechanical property requirements, processing and heat treatment guidance, surface quality and dimensional tolerances, mandatory testing and inspection methods, lot acceptance criteria, traceability, marking and certification. The specification is intended for raw material suppliers, processors and OEMs procuring titanium strip for critical aerospace applications.

Key topics and requirements

• Designation of applicable titanium alloys and tempers for cold-rolled strip.
• Specified chemical composition limits and maximum interstitials (oxygen, nitrogen, carbon, iron).
• Mechanical property minima: tensile strength, yield strength, elongation and sometimes hardness ranges.
• Requirements for incremental forming/cold-rolling processes and acceptable heat treatments to achieve required properties.
• Dimensional tolerances for thickness, width, edge condition and acceptable surface finish/defect criteria.
• Inspection and testing requirements: tensile tests, hardness, chemical analysis, microstructure examination and nondestructive evaluation where specified.
• Lot and sample acceptance plans, retest and rejection criteria.
• Traceability, certification, marking and packing requirements for delivered material.

Typical use and users

This specification is used by aerospace material suppliers, titanium strip manufacturers, heat-treatment and metalworking processors, and OEM engineering, procurement and quality assurance teams. Typical applications include manufacture of airframe and engine structural parts where cold-rolled, incrementally formed titanium strip is required for its strength-to-weight ratio and formability—examples include brackets, stiffeners, skins, and other structural components on aircraft and aeroengines.
