Understanding the different hardness testing types and systems can be useful to determine an optimal solution. Hardness testing functionality has evolved and now users can dial into world-class instrumentation which more closely aligns with their applications at hand.
Buehler announced its latest addition to the Wilson hardness testing range, the new UH4000 Se-ries Universal Hardness Tester. This tester comes in two key configurations: UH4250 Hardness Scale 0.5-250 kgf and UH4750 Hardness Scale 3-750 kgf.
Rockwell testing is the most commonly conducted hardness testing, as the testing procedure is simple and the readings can be directly attained from the testing machine.
Many new products entering the market today are based on new materials and are manufactured using novel processes. These new materials are playing increasingly important roles—supporting innovation and boosting competitiveness in technology-driven industries.
The conventional measurement of mechanical hardness, for instance, in steel, is usually carried out using the same principle. A mechanical indenter is forced towards the surface of the workpiece, penetrating it and leaving an imprint.
The L.S. Starrett Co., a leading global manufacturer of precision measuring tools and gages, metrology systems and more, will be demonstrating at IMTS a wide range of its latest solutions from Automated Vision Technology.
Buehler is introducing a Quick Ship program for the popular Wilson certified Rockwell hardness test blocks. For ultimate accuracy and performance in tester verification, Buehler has calibration sets available for most Rockwell scales.
We’ll cover some of the common problems associated with microhardness testing and address some of the techniques and technologies that can be used to avoid them.
The Vickers and Knoop microhardness testing methods have become invaluable for the testing of a variety of parts, which have what can be referred to as “shallow layer hardness.” Such characteristics as surface hardness, thin cross section, coating hardness, and case depth are measured using the microhardness testing methods. These methods also can be useful for selective testing of particular grains or constituents such as those found in powdered metal parts.
As applications continue to demand more of engineering materials and as the stakes for life expectancy of finished products continue to rise, testing is anticipated to play an ever more important role in product development and quality control processes.
