Why Hardness Testing Matters
Hardness, as applied to most materials, and in particular metals, is a valuable, revealing, and commonly employed mechanical test that has been in use in various forms for over 250 years. The information from a hardness test can complement and often be used in conjunction with other material verification techniques such as tensile or compression to provide critical performance information. Consider its significance in structural, aerospace, automotive, quality control, failure analysis and many other forms of manufacturing and industry.
