The Mohs scale of mineral hardness is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of various minerals through the ability 

H13 tool steel is a secondary hardening steel. It has good tempering resistance, good thermal fatigue resistance, and excellent heat cracking resistance, and maintains high hardness and strength at elevated temperatures. It is deep hardening and has a very high toughness, which allows hardening of large sections by air cooling.

Thus, if you need a rubber or O-ring durometer that feels like a running shoe sole, review our rubber hardness chart below, then pick Shore 70A. A rubber durometer of Shore 70A is the most commonly chosen material hardness for all applications. a. Shore 20A = Rubber Band b. Shore 40A = Pencil Eraser c. Shore 60A = Car Tire Tread d.

Brinell [HB] is one of the most common units used for listing the hardness of steel materials. the test is done with a 10 mm steel ball pressed with 3000 Kgf (6,614 Lbf). Common values for machined materials range from 100 HB for very soft materials up to 650 HB for heat-treated steels.. The advantage of Brinell [HB] over Rockwell [HRC/HRB], is that the whole range is covered on the scale

E448 Practice for Scleroscope Hardness Testing of Metallic Materials 3. Methods for Hardness Determinations 3.1 The hardness readings used with these conversion tables shall be determined in accordance with one of the following ASTM test methods: 3.1.1 Brinell Hardness—Test Method E10. 3.1.2 Rockwell Hardness—Test Method E18 ScalesA, B, C,

Converting hardness Rockwell B (HRB) to hardness Rockwell C (HRC) is a usual practice for many designers when specifying the hardness value of a material. This conversion is possible using charts and tables calculated using formulas to get approximate but acceptable values that can be interchanged for the different Rockwell hardness testing scales.

in order to determine if the resulting characteristics will work well in their applications. Take a look at our handy chart! Metal Hardness Chart

Determine the relative hardness of resins, film, lacquer, and paint by testing their resistance to scratches by graphite pencils. The pencils are calibrated to specific lead grades for hardness. The lowest hardness value of the pencil that mars the material is the material's relative hardness. Flatten the tip of the pencil lead with the included 400 grit sandpaper, then insert the pencil
