From routine quality checks to failure investigations, macroetch testing is an accurate, reliable method for assessing the metallic properties of materials ranging from stainless steel to beryllium. No matter your need, our highly trained metallurgists work with you to help understand your materials and get the most out of your products.
Our macroetch test services are offered at locations across the globe, and can be performed as standalone tests or as part of larger metallurgical testing projects. We work with you to determine the best etching methods for your projects, giving you the reliable, accurate results you need to ensure that your materials are without defect and fit for purpose.
Macroetch Test Procedures
Depending the size of the available material and the standard being used, our labs provide several methods for macroetch testing. Using a mixture of chemicals and compounds, macroetching removes the top layer of a sample to reveal material characteristics, structural elements and potential defects that can be observed without the use of a microscope (or using very low magnification).
Some of the features that we look for in a macroetch test include:
- Banding
- Corrosion
- Fractures and defects
- Grain size and grain boundaries (grains must be large)
- Surface discontinuities
- Macro structure
- Forging defects
The Сòòò½APP Advantage in Macroetch Testing
With global experts actively serving on professional and standards committees, including ASM and ASTM, we are consistently at the forefront of new testing techniques and material innovations. Our labs use state-of-the art equipment to ensure that your materials are fit for purpose and of the best quality.

The Effects of Martensite Content on the Mechanical Properties of Quenched and Tempered 0.2%C-Ni-Cr-Mo Steels
The martensite content in quenched and tempered steels plays a significant role in their mechanical properties, making the as-quenched microstructure critical to the material strength and hardness. LEARN MOREWhat is Metallurgical Testing?
Metallurgy is the science and technology of extracting metals from their ores, refining them and preparing them for end use. Metallurgical testing identifies the condition and makeup of materials, ensuring the product or component is fit for purpose. LEARN MOREMetallurgical Failure Analysis Helps Prevent Future Failures
When components fail, it can affect the delivery of goods and the safety of the general public. Performing metallurgical failure analysis is critical to preventing future failures.
