The Brinell hardness test (HBW) indentation leaves a relatively large impression, using a tungsten carbide ball. The size of the indent is read optically. Used for materials with a coarse or inhomogeneous grain structure Used for larger samples Suitable for forgings and castings where the ...
For HBS a hardened steel ball was/is used to determine the value. This is used for materials with a value below 450 such as mild steel and grey cast iron, however, the HBS method isn’t really used any longer, although it is sometimes still referred to.HBW indicates a cemented carbide...
National Physical Laboratory, India has recently established a primary standard for Brinell hardness scale (HBW), besides the existing Vickers (HV) and Rockwell hardness (HR) primary standards. The uncertainty associated with the Brinell hardness standard is found to be within卤1.5% for HBW1/1 to...
