Magnetic measurements are suitable to determine mechanical and technical properties of a material especially steel. The magnetic and mechanical properties of a material are determined by the microstructure. 

The purpose of this article is not to review all techniques, but to discuss particularly the application of hardness testing to coatings, typical techniques used, best practices and special considerations to ensure accurate and repeatable results.

Hardness testing is a simple mechanical test developed to provide a quantitative measurement in a quick and efficient manner. Hardness testing is used in place of other techniques such as tensile testing as it can be correlated with tensile strength but requires significantly less time and effort, as well as being comparatively nondestructive.

Component manufacturers across the manufacturing spectrum—such as in automotive, aerospace, electronics, medical, energy and other fields—must ensure that their parts meet engineers’ specifications.

The L.S. Starrett Co. has introduced two new digital Rockwell/ Superficial Rockwell Benchtop Hardness Testers (Nos. 3823 and 3824) with fully automated load/ unload procedures, and capable of providing highly accurate readings.

Most of us have had occasion to (or even reluctantly needed to) put a hammer to a nail, which makes the above analogy so relatable. 

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.

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.
