[PDF]So how much harder is 60 HRC than 59 HRC? | BladeForums
Jun 19, 2012 · I see rockwell hardness numbers thrown around a lot, but I've never really seen anything that clearly defines how much harder 60 HRC is than 59 HRC. I looked around at the way the HR numbers are actually calculated, and found that in terms of measuring the depressions and everything that are actually used to get the hardness value, there's only ...

Hardness Hardness is the property of a material that enables it to resist plastic deformation, penetration, indentation, and scratching. Therefore, hardness is important from an engineering standpoint because resistance to wear by either friction or erosion by steam, oil, and water generally increases with hardness.

A 4.6.1. with the exception of heat–treated wire of diameter .100" (2.54 mm) and larger, the Rockwell Hardness Test is not recommended for round wire. On such heat–treated wire the specimen shall be flatten on two parallel sides by grinding. For round wire the Tensile Strength Test is greatly preferred to the Rockwell Hardness Test.

The grinding ball in cast state has poor mechanical properties. Mechanical properties of grinding ball significantly increase after heat treatment After heat treatment of 950 °C * 2 h oil quenching and 350 °C *2 h tempering, grinding ball gets the best comprehensive properties. Compared with cast state, impact toughness and Rockwell hardness are increased by 55% and 26% respectively.
