Do you need to perform carbon steel and low-alloy steel analysis according to ASTM E415?
Securing metallic materials for the ASD sector with ASTM E415
In the Aerospace, Space, and Defense (ASD) sectors, mastering the chemical composition of steels is a safety imperative. Even the slightest variation in alloying elements or impurities can alter the mechanical performance and corrosion resistance of your essential parts.
ASTM E415 is the reference standard for the analysis of carbon and low-alloy steels by Spark Optical Emission Spectrometry (Spark-OES). It guarantees a rapid and extremely precise evaluation of steel grade compliance.
At FILAB, we support manufacturers in the ASD supply chain with the characterization and control of their materials according to ASTM E415. Our goal is clear: to ensure the reliability of your technical and industrial decisions.
ASTM E415: A key challenge for structural and high-performance steels
Steel analysis by spark-OES according to ASTM E415
The ASTM E415 standard defines a standardized test method for the quantitative chemical analysis of 21 elements (including Carbon, Manganese, Phosphorus, Sulfur, and Silicon) in carbon and low-alloy steels.
It is specifically used to:
- Precisely measure alloying elements and residual impurities.
- Verify compliance of steel grades against technical specifications (AISI, SAE, etc.).
- Control quality upon material receipt or following forging and casting operations.
In the Aerospace and Defense industries, adhering to the content limits defined by ASTM E415 has a direct impact on:
- Hardness and tensile properties after heat treatment.
- Weldability and structural integrity of assemblies.
- In-service behavior of strategic components subject to fatigue constraints.
ASTM E415 is therefore essential for material qualification, quality control, supplier validation, or failure analysis following a non-conformity.

FAQ
It applies to carbon steels and low-alloy steels. The method is particularly suited for solid samples whose geometry allows for a stable electrical discharge (sparking).
It allows for the simultaneous determination of Carbon, Manganese, Silicon, Phosphorus, Sulfur, Chromium, Nickel, Molybdenum, Aluminum, Copper, Vanadium, and other essential trace elements.
ASTM E415 relies on Optical Emission Spectrometry (OES). An electrical discharge (spark) is generated between an electrode and the sample, producing a light spectrum whose intensity at each wavelength allows for the quantification of the elements present.
- Receiving inspection on bars, sheets, or billets.
- Grade sorting in case of mixed stock.
- Verification of surface decarburization or carburization.
- Technical support for new supplier approval dossiers.
ASTM E415 is a direct solid analysis technique, much faster and ideal for routine control. In contrast, ICP (E3061) requires acid digestion (dissolution) and is often preferred for more complex matrices or when lower detection limits are needed for specific elements.
