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 the knife blade manufacturing business, hardness ratings follow a predetermined chart which is commonly called the Rockwell C scale. The higher the number on

Factors such as material hardness, formulation, chemical environment, working load, size tolerance (stability), etc. may affect individual materials differently.

This conversion chart contains valid data for commonly used materials in industries such as metalworking, healthcare, and dentistry. Other than metals, other materials that may be measured using the Vickers hardness test are ceramics, stone, wood, and leather.

Alumina represents the most commonly used ceramic material in industry. It provides superior abrasion, high temperature and chemical resistance, and is also electrically insulating. This material has an excellent cost-to-part life performance record. Purity levels are

2020.5.27. Machinability can help us to determine whether a type of material is suitable for CNC machining services. The machinability rating attempts to quantify the ease of machining of a range of metals. Here CNCLATHING.COM presents the material machinability chart shows the machinability of metals and plastics.

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
