Metal hardness is a characteristic that determines the surface wear and abrasive resistance. The ability of a material to resist denting from impact is related to hardness as well as a material's ductility. Various degrees of hardness may be achieved in many metals by tempering, a heat treatment process used in cold rolled and cold worked metals.
However, in most cases, it is better to compare the hardness of the rounded material with the hardness value of a flat piece, making correction factors necessary. In a cylindrical piece, the reduction in lateral support will result in the indenter penetrating further into the material which translates to lower hardness readings.

Hardness by itself also has nothing to do with whether a material is brittle or ductile. Of two materials with the same hardness, one might be brittle and the other ductile. What is hardness, then? To provide a somewhat circular and not very helpful definition, it's a measure of how a material performs in a hardness test.
Nylon 12 has a broad range of applications as polyamide additives. Nylon 12 is mainly used for films for packing material in the food industry and sterilized films and bags for use in the pharmaceutical and medical fields. When added to polyethylene films, it improves water vapor permeability and aroma impermeability.

Brinell TestThe Brinell test uses a hardened steel ball indentor with a diameter of 10mm. The indentor is applied to the test material under a load of 3000kg. The surface area of the indentation is then measured to derive the hardness, HB, of the material.Brinell testing is not suitable for very hard materials since the hardness of the test material approaches that of the steel indentor.

Hardness: A materials ability to withstand friction, essentially abrasion resistance, is known as hardness. Diamonds are among the hardest substances known to man, it is incredibly difficult to scratch a diamond.
Material Properties. Important properties of electrode materials are conductivity, corrosion resistance, hardness, current load, form, and size. Many of these are determined by inherent characteristics of the material. Conductivity is the measure of a materials ability to carry or conduct an electric current. It is often given as percent of best p12 material hardness
This requires this material should have very high strength properties, which do not deteriorate with time, and should be creep resistant. Advantages of P91.
