(Examples: 64 HRC = Rockwell hardness number of 64 on Rockwell C scale; 72 HRBW = Rockwell hardness number of 72 on Rockwell B scale measured using a tungsten carbide ball indenter.) The test must be conducted on a smooth, even surface that is free from oxide scale, foreign matter, and, in particular, free from lubricants.

Rockwell CScale Hardness Brale indenter, 150 kgf load. Then a major load (60, 100, or 150 kgf) is applied to create the full indention. The major load is reduced back to the minor load, and the indention depth measurement is taken. The penetrator is usually 1/16 inch in diameter, although larger diameters...
Metal Hardness Chart. The below chart is useful for determining which metals will be impervious to scratching and dinging, as it relates to the Rockwell scale and ductility. The Rockwell scale is a hardness scale based on indentation hardness of a material.
Oct 27, 2013· The Rockwell scale is a measurement system used by commercial manufacturers to determine the relative hardness of objects based on the depth of indentation from a heavy object. In other words, they drop a heavy ball or diamond cone onto the steel and measure the size of indentation. For knives they use the "C" scale in units labeled "HRC."

Dec 08, 2005· RE: Rockwell C Hardness Scale. 6 Dec 05 20:37. In Gilbert Ford Kinney's Engineering Properties and Application of Plastics, page 202. There's a comparison of several hardness scales. HRC range is from 20 to 80, where 80 is about in line with hardness of (8)Topaz in Mohs hardness. It also corresponds to approx.
Hardness (HRC) 3339: Surface Hardness (30N) max. Tensile Strength (psi) 150,000 min. Yield Strength at % Offset (psi) 130,000 min. Elongation (%) 12 min.
The Rockwell test of hardness HRc refers to the Rockwell Scale of Hardness, part C. The Rockwell scale is widely used by metallurgists to define just how hard a piece of steel is: the higher the number, the harder the steel. A particular metal's rating is important to the knife maker because a harder steel will hold an edge better than a softer steel.

Hardness of metal is determined by the carbon content. HRC is the Rockwell Hardness Scale. A hardness of 5558 is not very hard compared to carbon steel.
Talc has a hardness of 1 while diamond has a hardness of 10 on the mohs scale. You can test hardness at home by looking up the hardness of a common material and then scratching it or using it .
