For heat -treated material harder than Rockwell C20, use the optional C - scale diamond indenter . The Rockwell hardness scale is designed to determine the hardness of materials like aluminum, thin steel, lead, iron, titanium, copper alloys, and cemented carbides. The Rockwell scale is a hardness scale based on indentation hardness of a material. In all, the Rockwell hardness of a knife will always be different between high-end knives and low-end knives, for example, an M390 steel knife is a 62HCR compared to 420Hc steel knife which has a 58HCR, it doesn’t necessarily mean that the M390 is better than the 420HC, yes the M390 Is a premium steel with high quality, but it depends on your usage too, for example, both a … In other words, the more pressure that is required to indent the surface, the higher the number on the scale will be. Although there is no accurate conversion tables and equations, but dandong foundry recommend the following formulas and comparison tables according to the experience and standards. Brinell hardness of stainless steel – type 304 is approximately 201 MPa. and Rockwell superficial hardness of cartridge brass. Since the Rockwell test needs to make an indent in the test piece, there’s a minimum thickness associated with the test. Rockwell hardness tester gives hardness numbers directly. Brass is an excellent metal for cold working and is easily shaped. Move mouse pointer over the hand wheel to apply 10Kg minor load on the specimen. The most common Rockwell variants include: Hardness of Brass – Cartridge Brass – UNS C26000 . Rockwell Hardness Test is carried out by making contact of material with the indenter and applying a 10 kg minor load, this results in an indenter to hold the specimen firmly at a place.After that depth of impression is observed. If the material is too thin, you’ll be measuring the hardness of the supporting anvil more so than the test piece. The smaller the indentation value, the harder is the material. The Rockwell hardness test uses three test forces and three indenters, which have a total of nine combinations, corresponding to nine scales of Rockwell hardness.
