The 1.5634 is next to the 1.2767 the "classic" as a light element for damascus steel production. Depending on the desired properties of the finished Damascus steel, one usually decides on one of the two steels.
The 1.5634 is characterized by the following features:
- Due to the low chromium content, it can easily be conventionally fire welded.
- Due to the relatively high carbon content of 0.75%, compared to the 0.45% of the 1.2767, it is well suited for the production of high-performance damascus steel, since the total carbon content of the finished damascus steel is less reduced.
- With its 2.0% nickel, the 1.6534 draws light silver when etched correctly.
I can recommend the following damask combinations:
High performance damascus steel:
Very hard and wear-resistant:
- 1.6534 in combination with 1.2562 and possibly 1.2510
- 1.6534 in combination with 1.2063 and possibly 1.2510
- 1.6534 in combination with 1.2419.05 and possibly 1.2510
Hard, tough and wear-resistant:
- 1.5634 in combination with 1.2510 and/or 1.2419
Hard and very tough:
- 1.6534 in combination with 1.2510 and 1.2003
Decoratice damascus steel:
- 1.6534 in combination with 1.2003 and 1.8974 (silver-gray-black)
- 1.6534 in combination with pure nickel, 1.2003 and 1.8974 (light silver-silver-gray-black)
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.
2x30x512mm = 245g
2x40x512mm = 322g
2x50x512mm = 402g
3x30x512mm = 365g
3x40x512mm = 485g
3x50x512mm = 600g
Rolled, sandblasted, annealed
The strips are cut with a pair of guillotines and can therefore have minimal warpage, which can, however, be easily straightened.
The 3mm thick strips have some rust film but no rust scars.
|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: 820 °C (4-6 min holding time)
Quenching: Oil, AAA-DA or Durixol V35
Tempering: 175°C to max. 200°C. (400 °C for spring rate)
Achievable hardness: 58-61 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.
