Meeting the chemical control requirements for alloys
In demanding industries, particularly aerospace, compliance of an alloy’s chemical composition determines material acceptance, process control and supply traceability. AMS 2249 sets out the chemical control limits applicable to wrought nickel- and cobalt-based alloys. A material analysis makes it possible to compare measured contents with the requirements applicable to the grade, batch and customer specification. It helps identify a composition deviation, secure material receipt or document a quality investigation.
Defining an analysis plan suited to the grade
The inspection plan is defined based on the designation of the alloy, the applicable specification and the purpose of the test. It may cover the main alloying elements, as well as residual elements or impurities subject to specified limits. The quality of the sampling and its representativeness are decisive for obtaining usable metallurgical analysis.
Using analytical methods suited to metals
The choice of method depends on the elements being investigated, the target content levels, the metal matrix and the amount of sample available. The Filab laboratory selects analytical methods suited to the characterization objective and prepares the test specimens or samples required for measurement.
Securing sample collection and identification
A part, production offcut, coupon or chips can be analyzed depending on the requirements and selected method. Each sample must be identified, linked to its declared grade and accompanied by the available information: batch number, metallurgical condition, product form, specification and purpose of the control.
Carrying out an AMS 2249 analysis at the Filab laboratory
The Filab laboratory supports industrial companies with their analysis according to AMS 2249, from defining the requirements through to issuing the results. The teams take into account the nature of the material, the sampling form, the elements to be quantified and the reference standard provided by the customer. The service can be integrated into a broader metallurgical analysis program to characterize the material and support quality control decisions.
Obtaining interpretable results for material control
Results are presented as content levels for each element to facilitate comparison with the stated limits. In the event of an apparent non-compliance, the Filab laboratory can help identify relevant additional checks, depending on the industrial context and available documentation.
Supplementing chemical analysis with metallographic examination
When justified by the investigation, composition analysis may be combined with examinations of structure, surface or defects. Observations made in the laboratory using SEM provide, in particular, additional insight into the metallurgical condition of a part or product.
The Filab laboratory also supports you with:
Adapting the request to production constraints
Before shipment, the Filab laboratory teams can clarify the required packaging, material quantity and technical information to provide. This preparation helps efficiently direct the material analysis and reduce additional exchanges before testing.
Benefit from decision-oriented support
Filab laboratory combines expertise in material characterization, test program definition and reporting of actionable results for quality, procurement and production teams. To launch your project, send your specification and material information, discuss the inspection plan, then receive a proposal tailored to your analysis needs.
