- Details (Sizes)
- This non-stainless Damascus steel consists of steel from the cannon barrel of a Leopard tank in combination with a tool, bearing and cold work steel, to form a total of 620 layers.
- The plate is annealed, ground flat, and is slightly etched before shipment.
- With proper heat treatment, the hardness of this steel is about 63HRC, and is thus harder than glass. Hardening is done in a vacuum or with inert gas at 850 degrees, with a retention time of up to 5 minutes.
- The cooling rate is equivalent to that of an oil hardening. For the conversion of retained austenite, either a freezing process at 90 °C or a tempering process at 140 °C takes place. Next, a tempering process at 150 °C should be carried out to assure the complete transformation of retained austenite to martensite.
