The classification and quantifying of inclusions in steel is a very important factor in steel manufacturing. We can perform inclusion content/ratings on steel samples to common international standards such as ASTM E45, DIN 50602, ISO 4967, and SAE J422. Through the use of automated polishing, and a microscope and software known to be the gold-standard of inclusion rating, we can take care of any volume of sampling and provide quick and accurate inclusion severity ratings to many specifications at once.
Grain size has a large effect on many of the properties that are used for engineering a product out of an iron or steel product. We have the capability to perform average grain size measurements to common international standards such as ASTM E112. Through use of our metallographic preparation and optical microscope, we can report a grain size number accompanied with a photomicrograph of your sample.
Carbon depletion can occur in uncontrolled atmospheres at high temperatures, causing your material to have a difference in carbon content at the surface. We can perform an analysis of decarburization to common international standards such as ASTM E1077. You will receive a report that includes the depth of complete, partial, total decarburization, and a photomicrograph of the surface of your sample.
Microstructure constituents can often show up in requirements for wrought or cast products. Whether it is an as-cast or as-rolled microstructure requirement, or if a heat treatment is needed to gain the correct structure, we are capable of analyzing items such as graphite flake formation, percent ferrite, percent pearlite, and percent spheroidization. We perform these to common standards such as ASTM A247, ASTM A892, and ASTM F2282, but also use automated software evaluation when standards are not available.
