Materials for Making Damascus Steel

In producing conventional damascene blade, for ex. high carbon and low carbon and/or nickel alloyed steel flat bars with a width of 20 mm are used. Those are cut-off to lengths of ca. 80 mm. Then they are laid one on the other and borax is added between the layers. Borax melts the surfaces oxidized in glowing state and removes the slag in order to achieve good weldability. The package can include 5 – 10 layers depending on the material thickness. The ends of the package are then closed tightly by welding. The rod serving as a handle is welded at the same time. The surfaces of flat bars must be clean and preferably ground. The pack is heated up evenly, so, that also the inner layers become hot enough. In the forging heat, borax is added to remove slag and to achieve good welding properties. This is repeated until all seams between adjacent layers have been treated with borax. After the first forging, the package is drawn out to approx. double length, maintaining the width unchanged. Then the package is almost broken in the middle with a chisel and the parts are folded one on the other. These steps are repeated until reaching the required amount of layers. The result is a laminated bar with tens – even hundreds of layers. The ornamental patterns can be made by twisting, cutting or forging.
