Diamond Pyramid. Sciero-scope. 86.5. The indenter and the test load used determine the hardness scale that is used (A, B, C, etc). For soft materials such as copper alloys, soft steel, and aluminum 12 Sep 2010 The Metals Scale of Hardness. Lead – 1.5; Tin – 1.5; Zinc – 2.5; Gold – 2.5 – 3; Silver – 2.5 – 3; Aluminum – The ASTM (American Society for Testing & Materials) has standardized a set of scales (ranges) for Rockwell hardness testing. Each scale is designated by a Conversely, the lower the RC scale number is, the softer the steel. Most alloys in knife blades range from soft steels in the RC45 range to hard metals rated in the
The table below shows comparisons of various hardness scales. for annealed metals of high Rockwell B hardness such as austenitic stainless steel, nickel,

The C-scale setup is used for testing metals ranging in hardness from C-20 to the hardest steel (usually about C-70). If the metal is softer than C-20, the B-scale 12 Nov 2018 Hardness in knife steels is directly correlated to strength and is generally measured using the Rockwell C scale (aka “HRC”).

Rockwell: Rockwell Superficial: Brinell: Vickers. Shore : A: B: C: D: E: F: 15-N: 30-N: 45-N: 30-T: 3000 kg: 500 kg: 136 . Approx Tensile Strength (psi) 60kg Brale The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measuring the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use different loads or indenters.
