A tool steel alloyed with tungsten and chromium with high achievable hardness and very good toughness. Lire plus..
1.2419 is a low-alloy tool steel containing tungsten and chromium, which is characterized by a high level of hardness that can be achieved and very good toughness. In the performance range of tungsten steels, it lies between 1.2510 and 1.2419.05.
With correct heat treatment, it achieves a maximum working hardness of 64 HRC and a higher wear resistance than 1.2510. At the same time, it offers more toughness and "power reserves" than 1.2419.05.
The steel is equally suitable for outdoor and kitchen knives. I recommend it for all knives that should be significantly more tough than the high-carbon steels 1.2419.05, 1.2063 and 1.2562, but at the same time should be more wear-resistant than 1.2510.
Due to the overall still relatively low content of carbides, the steel is excellent for finely ground cutting edges.
In Damascus steel it is relatively dark, but remains slightly brighter than 1.2510. That's why I like it for Damascus steels, where maximum performance is more important than extremely strong contrasts.
I myself do not offer a hardening service for the steels I sell. However, I can unreservedly recommend the hardening service of my colleague Jürgen Schanz. He works with a very experienced hardening shop that also carries out demanding heat treatments exactly according to customer requirements. If necessary, contact Jürgen Schanz directly via his contact form.

The material is cut with guillotine shears. Some of the pieces have a greater distortion, but this can easily be straightened out by bending them or using a soft-faced hammer.
|Recommended heat treatment:||
Forging: Form forging (heavy deformation) between 1100 °C and 850 °C. Fine forging (minor deformation) between 850 °C and 750 °C.
Normalize: 2x Heat up to 840 °C and immediately cool in air to below 721 °C (Ar1). Then 3x heat up to 800 °C and immediately quench in oil until the glow color has disappeared.
Soft annealing: hold at 720 °C for approx. 60 minutes, then cool down in the furnace.
Hardening: 810 °C (6-8 min holding time) or 840 °C (3-5 min holding time)
Quenching: Oil, AAA-DA or Durixol V35 (recommended at 810 °C hardening temperature)
Tempering: 175°C to max. 200°C. 2x one hour each, water cooling in between.
Achievable hardness: 61-64 hrc.
Note: A deep freeze treatment (-70 °C) between hardening and tempering can reduce the retained austenite content and thus increase the working hardness with the same toughness.
