Turning the hard way | Cutting Tool Engineering

Hard turning is commonly considered to start with materials of 45 HRC, with a transition zone up to 50 HRC. In that zone, some harder carbide and cermet inserts still work. Coated and uncoated ceramic grades work for a hardness range of 45 HRC to about 60 HRC while CBN inserts are designed for about 50 HRC to 68 HRC.

What the Rockwell Hardness Scale Can Tell You About a …

For example, the average axe has an HRC of about 50, so the sharpened edge can withstand the impact of being hurled into a solid piece of wood without snapping off. An HRC rating of 52-54 is soft but would make a reasonable, inexpensive kitchen knife. Professionals and experienced home cooks look for kitchen knives with an HRC rating of …

Knife Steel Hardness Ratings Explained & Compared

Choppers, Machetes, and Field Knives: 52 to 55 HRC. Between these C Ratings, a blade's edge is unlikely to chip or crack. Instead, it will roll and dull after repeated heavy use. Sharpening at this hardness rating is easy, too — an important advantage for a large blade with a long cutting edge. Everyday-Carry Utility Knives: 54 to 56 HRC

Rockwell to Brinell Hardness Conversion Chart

For instance, converting from a Rockwell hardness test on the C scale (HRC) to a Brinell hardness test value requires using the formula: BHN = 5.970 x (HRC + 104.7). This formula gives an approximate value for the Brinell hardness value, and quality assessment professionals use it to create the conversion tables and charts for instant ...

Hardness Conversion Calculator: HRC, HB, HV and HRB

The test is done by measuring the surface area of the indentation created by a diamond in the shape of a square-based pyramid. The HV number equals the force divided by the area (F/a). Carbide grades are usually in the range of 1,300-1,900 HV. Ceramics can reach a hardness of 2,000 HV, CBN up to 3,000 HV, and PCD up to 6,000 HV.

Commonly used HV-HB-HRC hardness comparison table

The applicable range of HRC scale is 20~70HRC. When the hardness value is less than 20HRC, because the conical part of the indenter is pressed too much, the sensitivity is reduced, then the HRB scale should be used; when the hardness of the sample is greater than 67HRC, the pressure on the tip of the indenter is too large, and the …

HRC to Vickers Hardness Conversion Chart

The measurement is then converted to hardness value using the percent obtained for each area of diamond penetration in the Vickers Hardness Scale. You should use the HRC to Vickers hardness conversion chart above to convert a value from the Rockwell scale to the Vickers scale. This will make it easy to determine a material's hardness in both ...

Tempering

Tempering can be divided into three main groups: Low temperature (160-300°C): used for case hardening components and cold working tool steels. Typically, hardness requirement is around 60 HRC. Tempering of spring steels (300-500°C): used for spring steels or similar applications. Typically, hardness requirement is around 45 HRC.
