What is the average hardness of a temper?What is the average hardness of a temper?The typical tempering range is 350 to 400ºF (177 to 204ºC). For 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.D2 Steel D2 Technical Data - Tool Steel High Speed Steel What is the best HRC to D2?What is the best HRC to D2?Our heat-treatment specialist give hia hearty recommendation the best HRC to D2 is HRC 58 to keep endurance. My customers are also interested in the hardness and they are satisfied with their HRC58 stuffs. But somebodys require HRC 60. They seem to be considered the HRC58 to save the cost. Anyway, Is there any difference between the two? Thanks.Has it some difference between HRC 58 and 60? BladeForums What is the hardness of D2?What is the hardness of D2?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.Has it some difference between HRC 58 and 60? BladeForums

What the Rockwell Hardness Scale Can Tell You About a hardness 58 62 hrc high temperature

Jun 10, 2019Generally, a knife with a Rockwell Hardness Scale rating of 58-62 will hold an edge better than a blade that has a lower HRC rating. Japanese-style knives tend to have HRC ratings of 60 and above. But steel thats too hard can make a knife blade brittle and lower its tensile strength, so the knife will be easy to damage if misused.1.4125 / 440c Technical DataAs quenched hardness 60/62 HRc. The upper end of the temperature range should be used for larger sections or when maximum corrosion resistance and strength are required. Similarly the greater quench pressure should be used in order to maximise these properties.1.4125 / 440c Technical DataAs quenched hardness 60/62 HRc.

It has high wear and abrasion resistant properties. It is heat treatable and will offer a hardness in the range 55-62 HRC, and is machinable in the annealed condition. D2 steel shows little distortion on correct hardening.

High Speed Steel D2 Steel D2 Technical Data

For 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).Knife Rockwell Hardness and the Best Rockwell hardness Before we go into it, just to be clear, there is no best Rockwell hardness for a knife. Why? because its related to many factors, for example, a kitchen knife purpose isnt the same as a hunting a knife, a Chef would rather be having a knife with a high hardness like an HRC of 62 or more that will be great in edge retention, while a hunter or a camper would like to have a lower HRC easy to hardness 58 62 hrc high temperatureKnife Steel Basics - CrucibleHardness in knife steels is most commonly measured using the Rockwell C test.
