Would this be of use in illustrating the concept?--128.115.27.10 20:18, 5 April 2007 (UTC)

HBS compared with HBW[edit]

What hardness is HBS good up to ? How does that relate to the hardness of the ball used ? Do HBS and HBW match for softer materials ? up to what HBW ? Rod57 (talk) 13:06, 17 April 2010 (UTC)

Could article say what variation in hardness might be calculated using different forces and indenter diameters ? Rod57 (talk) 13:06, 17 April 2010 (UTC)

What is BHN?[edit]

Somebody missed to add all the explanations for the formula.
Please add them.

Dimensionless?[edit]

Why is this article classified in the category of Dimensionless numbers? Is not Brinell hardness a quantity that has the dimension of pressure? Doesn't it follow from the definitions in this article that the unit of BHN, as defined here, is kgf/mm² (in gravitational metric system), and that the unit of HBW is N/mm², which is the same as one megapascal (in SI units)? Both are units of pressure. -FKLS Maybe it is customary to omit its units, but these are what the numbers really mean. (talk) 07:08, 7 March 2014 (UTC)
