| With optimized heat treatment, 1.4034 can achieve a hardness in the range of 58–60 HRC, offering quite good edge retention. In comparison, it is often hardened to only about 52–55 HRC in many industrial and production knives, which means the steel’s full potential is only partially utilized. |
1.4034 steel / AISI 420HC or Böhler N540 (x46cr13) is a hardenable chromium steel.
Properties
Recommended applications
Hardness potential and practical values
For 1.4034, alloy tolerances—especially in carbon and chromium content—have a noticeable effect on achievable hardness. Therefore, for example, 60–61 HRC is not always realistically attainable. In our experience, with high-quality 1.4034, a maximum working hardness of 59–60 HRC can be achieved, and in individual cases even up to 61 HRC.
If the heat treater manages to achieve these high HRC values without the microstructure becoming coarse, the range of applications expands further. This allows for very fine geometries, such as those found in razors or Japanese chef’s knives.
1.4034 is not always pushed to its full maximum, as this requires very precise heat treatment, and in many cases a somewhat more moderate hardness is the more balanced solution. For most knife blades, hardness values of about 57–59 HRC have proven to be the most practical range.
