1.1 Rockwell Hardness Testing In a Rockwell hardness test, initially a minor load of 10 N is applied and the zero datum position is established. The major load (60, 100, or 150 N) is then applied for a specific period (a few seconds) and removed, leaving the minor load applied. The ...
In the knife blade manufacturing business, hardness ratings follow a predetermined chart which is commonly called the Rockwell C scale. The higher the number on the RC scale, the harder the steel is. Conversely, the lower the RC scale number is, the softer the steel. Most alloys in knife b...
