Hardness is a measure of a steels resistance to deformation. Hardness in tool steels is most commonly measured using the Rockwell C test. Hardened cold work tool steels are generally about 58/64 HRC (hardness Rockwell C), depending on the grade. Most are typically about 60/62 HRC, although some are occasionally used up to about 66 HRC.
Has it some difference between HRC 58 and 60 Jun 29, 2006 · It isn't the hardness which is critical but how it is hardened. D2 has three rough ranges, very low temper of 300F for 62/64 HRC for maximum hardness and wear resistance, moderate at 500F for 58/60 HRC for a combination of properties, and above 950F for 58 and under for optimal toughness. All of these hardness values will be elevated by oil+cold.
High Speed Steel D2 Steel D2 Technical DataFor maximum wear resistance, temper between 300-350°F (149-177°C) for a hardness of 62-64 HRC. For the optimal balance between wear resistance and toughness, temper between 500-550°F (260-288°C). This will produce 58-60 HRC. For maximum toughness, double temper, 2 hours plus 2 hours, at temperatures above 950°F (510°C).
D2 is an air-hardening, high carbon, high chromium tool steel, heat treatable to HRC 60-62. It offers excellent abrasion resistance, due to a large volume of carbides in the microstructure. D2 has been widely used for many years in cold work applications requiring very high wear resistance.
Japanese Knife Blade Steels Seisuke KnifeVG1:A predecessor of VG10, VG1 is an amazing steel with much of the same qualities as VG10. The metallurgic content is a bit different however. HRC of 58+ R2/SG2:R2/SG2 is a high-carbon high alloy content stainless steel that has been powderized into a very fine grain and then sintered back together. This process allows for a very consistent gran structure in the steel which makes the blade
Kitchen knife hardness comparison - TormekOct 30, 2014 · I use a nice, thick slab of stainless steel as it's sanitary and easy to clean. Just kidding. Wood or thermoplastic. I'm sure a SG2 or ZDP-189 HRC 62+ would be very nice. Really sharp, hard steel. They are just a little pricey. I have a Wusthof that seems to do better than some others, but still it's only HRC 58. HRC 62+ is would be much harder
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. Thats why knife makers try to find the balance in the steel by adding different
Knife Steel & Handle Material Chart - MidwayUSAIn recent years, this steel has made a resurgence in the knife industry, offering good blade toughness, edge holding capability and corrosion resistance. Fairly easy to resharpen. 58-62:420:A hard, strong blade steel. This stainless steel is commonly used in knife
Knife Steel Basics - CrucibleProperties of Knife Steel Hardness is a measure of a steels resistance to deformation. Hardness in knife steels is most commonly measured using the Rockwell C test. Hardened knife steels are generally about 58/62 HRC (hardness Rockwell C), depending on the grade. Most are
52-54 HRC:Quite soft steel, reasonable quality. 54-56 HRC:The hardness of many French chefs knives. The steel is hard enough for kitchen use, but regular use of a sharpening steel is required to keep the knife sharp. Knives of this hardness are usually easy to sharpen. 56-58 HRC:Hardness applied for professional German kitchen knives.

Tool Steel Resource Guide A2, D2, M2, S7, O1, W1, A6 M42 tool steel is a molybdenum high speed tool steel with 8-10% cobalt added for increased hardness and hot hardness that is superior to other high speed grades. This results in a sharper cutting edge that lasts longer, even when being used to machine high-hardness and hard-to-machine alloys in heavy duty and high production applications.
Hardened steel knives are dangerous to throw because they may shatter, chip, or break upon hard impact. Harder Steel. 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

In general, a knife must have an HRC of at least 52 to be usable. Some knives may have an HRC as high as 66, but hard knife steel is typically in the 58-62 HRC range.
