Analysis of steels according to ASTM E3515 by ICP-AES

Control of chemical composition determines the mechanical properties, weldability, corrosion resistance and fitness for use of steel. In production, during a failure investigation or as part of supplier quality control, a variation in elemental content can compromise the compliance of a grade or the interpretation of a quality deviation.

An analysis of steels performed according to a suitable protocol makes it possible to quantify the constituent and residual elements present in the material. The Filab laboratory assesses your requirements with regard to the ASTM E3515 analysis reference, the metallic matrix, the elements being investigated and the applicable decision thresholds.

ICP-AES is suitable for the simultaneous investigation of numerous metallic elements present in steels. Depending on the requirements, the analytical program may target chromium, nickel, molybdenum, manganese, copper, silicon, vanadium, titanium, niobium, cobalt or aluminum, among others.

The final list of elements is defined with the client based on the target grade, specifications, material requirements or investigation objectives.

The Filab laboratory can examine metal parts, coupons, chips, powders, wires, sheets, bars or fragments taken from an identified area. The sample should be accompanied by useful information: material designation, product history, sampling area, elements to be investigated and compliance requirements.

The ICP-AES analysis makes it possible to measure several elements in the same test solution. It is a relevant solution for characterizing the elemental composition of steel, comparing a material with a specification or investigating a composition nonconformity.

The Filab laboratory uses ICP-AES analysis for multi-element determination in steels, following preparation and dissolution adapted to the nature of the sample. This approach supports industrial companies in the inspection of raw materials, finished parts, semi-finished products, rejects or metallic deposits.

Each request undergoes a technical review to define the elements to be measured, the required sample quantities and the expected reporting format. For additional requirements related to metallurgical processes, discover how Filab supports foundry industry professionals.

The quality of the result depends on the representativeness of the sample and its preparation. Before dissolution, the Filab laboratory examines the surface condition, geometry, any coatings and potential heterogeneity. This step makes it possible to adapt the protocol to the matrix and ensure reliable interpretation of the measured concentrations.

When composition may vary between different areas, a targeted sampling plan can distinguish the bulk material, a heat-affected zone, a weld or a deposit. The Filab laboratory can guide sample preparation so that the analysis of steels addresses the industrial question at hand.

The choice of method depends on the target elements, expected concentrations, nature of the matrix and acceptance criteria. The Filab laboratory verifies the suitability between the objective of the ASTM E3515 analysis and the required analytical performance. For other standards-related requirements, consult our analysis laboratory according to ASTM E165.

To prepare your project, provide the reference of the applicable standard or specification, the steel designation, the elements to be tested, the number of samples, and your target turnaround time. The Filab laboratory will assess the analytical feasibility and define a suitable proposal.
