WebRockwell scale [HRC] Rockwell [HRC/HRB/ HRA] is one of the most common units used for listing the hardness of machined materials. the test is done by measuring the depth of penetration of a sphere under a large load compared to the penetration made by a reference preload. The Rockwell scale is divided into 9 sub-scales marked by letters A-K. jwplayer 埋め込み ダウンロードWebWhen testing the hardness of a material, you may need to convert your test results from one scale to another.
