DSC®-145 Damascus Steel (Stainless)

DSC stands for “Damascus Steel Super Clean”, and is manufactured and patented by Markus Balbach under No. 30 2008 009 468.

The term “super clean” designates extremely fine and pure steel. DSC, which is corrosion resistant and stainless, is produced and specially treated by a weld bonding process which prevents the build-up of contaminants in the steel or the welding seams.

  • This pure weld-bonded steel reacts with very low distortion when heat-treated.
  • The connections of the welded layers of steel do not separate during further reshaping or burr removal.
  • The cutting performance of the blades is superb due to the hardness between 59-62 hrc and is extremely ductile, while also having a low degree of brittleness.
  • DSC-145 ® consists of 80 to 500 layers.
  • DSC-145 ® is available in following matterial bonds:
  • 1.4034 and 19C27
  • Sandvik 14C28N and 19C27
  • Böhler N690 (1.4528) with Buderus Nitro-B (1.4916 nitrogen-alloyed)
  • DSC-145 ® stainless is a ferro-chrome martensitic composite and is laid out on quality, not optics.

These positive properties and safety features of the blade steel are important for production and processing and therefore make this Damascus steel especially suitable for use in industrial production.

Heat Treatment:

The heat treatment is applied at a hardening temperature of 1040-1080°C in a vacuum or with a hardening film. Holding on temperature for 15-20 minutes. Quenching on air.  The annealing temperature is 190-200°C for to 2 hours. This steel is suitable for use in freezing temperatures. The utilisation and final hardness after tempering is up to 62HRC. Higher or lower utilisation hardness is possible with an appropriate annealing temperature.

Etching:

- In a solution of ~25-30% of warm (<50°C) sulfuric acid or
- In >a solution of ~25-35% of warm (<50°C) hydrochloric acid or
- In a warm (<50°C) mixture of (25-30%) sulfuric acid and Fe3Cl in a ratio of up to 2:1

Neutralize it and polish or revise with fine water sandpaper. Deep etching is possible.
