HRB (ball) test is used for soft and medium hard metals while HRC (cone) is used for hardwoods and typically heat-treated materials. The total possible penetration depth of the indenters is 0.2mm (HRC) or 0.26mm (HRB) and is divided into 100 parts by HRC method or 130 for the HRB method, so hardness at Rockwells method is:1e=0.002m.

Brinell testers help you accurately test steel parts such as castings and forgings. Use a Vickers tester to help assess the hardness value of small precision parts,
In All, the HRC is a measurement of hardness, now lets jump to the knife part! Knife Rockwell hardness Every knife steel has its own specific HRC, from 54 HRC To 64 HRC, so youll be assuming the higher the HRC the better for the knife , well thats not correct, because we must not forget that hardness grows at the cost of toughness , the harder the steel the more it loses its toughness and vice versa. Rockwell Hardness (HRC, HRB) to Brinell Hardness (HB or Rockwell C Hardness (HRC) Brinell Hardness (HB) From 21 to 30:HB = 5.970 * HRC + 104.7:From 31 to 40:HB = 8.570 * HRC + 27.6:From 41 to 50:HB = 11.158 * HRC - 79.6:From 51 to Rockwell Hardness Guide What it is, How to Measure, & The Rockwell hardness number is not the same as the calculated depth differential measurement. Softer metals allow for deeper penetration than harder metals, so the B A value will always be higher on soft metal test subjects than hard metals. The Rockwell hardness scale number appears inverse to the depth differential calculation.

Sharp Jun 26, 2020 · An HRC rating between 52 and 54 is softer than higher ratings, but it offers less expensive kitchen knives or materials for other applications. An HRC55 or above rating usually represents harder materials and better reliability, strength and longevity.
Premium steels range from 59-66 HRC. As modern metallurgy advances, it is entirely possible these numbers might go up. Typically, a good everyday use pocket knife is about 57-59 HRC. You will be perfectly happy with a steel that hard. We have great success hardening 8Cr13MoV to the 57-59 range and it performs admirably. When you start getting into steels higher than 59 HRC, you are most likely Understanding the Hardness of Metals designnewsFor example, an extremely hard steel might have a hardness of 64 HRC, while a fairly soft steel might have a hardness of 70 HRB. Which scale is best to use? It depends on what you're measuring. The Rockwell C scale is good for measuring hardened steel. What is Rockwell Hardness and What Does it Mean? Knife Mar 02, 2017 · The HRC which also goes by other abbreviations like RC lets you know the hardness of the steel. A low HRC number means the steel is softer and a higher number means its harder. Its easy to assume that a higher number is better
HRc refers to the Rockwell Scale of Hardness, part C. The Rockwell scale is widely used by metallurgists to define just how hard a piece of steel is:the higher the number, the harder the steel. A particular metal's rating is important to the knife maker because a harder steel will hold an edge better than a softer steel.
