Damascus steel billets, steel blank, for damascus steel knife making

Pattern: Rose, Star, Water ripple, Spiral, Wave, Water flow, Nebula, Dots, Feather, Dragon Bone, wheat ears,Bubble, Peacock tail feathers,Buttons, raindrops Material: Forged Pattern Steel（Not Acid etching steel） Size: 160*30*3mm、220*30*3m、250*40*4mm。 (If you need other sizes, such as 300 * 50 * 3mm, please contact me first) Sanwich pattern steel, You can see the forged layer on the side by grinding and pickling. There are about 30 layers on one side and 60 layers on the whole. Middle steel core heat treatment to HRC 57-58. This steel is superior to steel 1095/15n20, especially in terms of rust and toughness. 1095/15n20 does not have such good toughness after heat treatment. The double-sided steel is about HRC24 The steel billet has been heat treated and quenched. When you receive it, you can directly start processing: 1. Perform flat grinding and polishing according to the knife shape you want, and add water while grinding to avoid annealing. 2. After polishing is completed, use high-concentration lotion such as ferric chloride, sulfuric acid, hydrochloric acid, etc. for pickling again Notice: 1. This is a material that has been flattened and pickled. The cost is 1.5 times or more than the material without flat grinding/pickling. [Because Flat grinding, at least 0.5 mm should be worn off on both sides.] 2. The steel material is not 100% straight, just a slight stress deformation during the heat treatment process, which is the characteristics of the steel embryo. You may need to use a grinder during the diy process. 3. Diy novice please follow the parameters, search for the corresponding tutorial and then start.
