Strength Characteristics of Metal – Hardness, Toughness, Ductility & Elongation 

Hardness is a measure of a material’s ability to resist abrasion and indentation. For carbon steels Brinell & Rockwell hardness testing can be used to estimate tensile strength. Toughness is a material’s ability to absord impact or shock loading, and is rarely a specification requirement. Ductility is the measurement of a material to deform before it fails and … Read more
