ASTM E381 PDF

More E The method employs the action of an acid or other corrosive agent to develop the macrostructural characteristics of a suitably prepared specimen. Sulfur printing shall be performed in accordance with Practice E Examination and rating of specimens shall be in accordance with Sections 10 and 11 of this E standard. Continuously cast steel blooms and billets, in the as cast condition, shall be examined according to the procedures described in Sections 10 and With reductions over a area ratio, wrought product from continuously cast steel may be examined according to Section 9.

Our labs can perform many reliable metallurgical testing methods, each with distinct advantages. Let us help you determine if macroetching is the best option for your material. More Less Macroetch testing can be used across a variety of applications, and is most often applied when looking for surface characteristics of a material. Some common uses for macroetching include: Quality control Macroetch testing is frequently used as an efficient, effective method of quality control in batches of material.

By testing samples from batches of material after manufacturing is complete, we can ensure that no defects occurred during processing, and that the lot is ready to be used for any project.

Failure analysis Often, the surface characteristics of a metal offer important clues about why a failure has occurred. Using macroetching techniques, we can determine at what point failure may have occurred, and what caused it manufacturing defects, material inconsistencies, etc.

Material selection Choosing the right material for an application is extremely important, and can often be a difficult task. We apply macroetch techniques to help determine what materials have the right combination of characteristics to ensure the success of a product or system. Sample preparation In addition to its uses as a standalone procedure, macroetch testing can also be used to prepare samples for additional testing.

From setting up a material for microscopic examination to pre-penetrant cleaning for non-destructive testing , macroetching can be a useful tool across testing disciplines.
