The difference between HBS and HBW is the indenter. 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 sometim...

HBW is calculated in both standards using the SI units as: where: F= applied force (N) D= diameter of indenter (mm) d= diameter of indentation (mm) When quoting a Brinell hardness number (BHN or more commonly HB), the conditions of the test used to obtain the number must be specifie...
