Forging blades from secret niobium steel from the Su-27 aircraft cannon.

It is impossible to weld by forge welding. After conducting a number of experiments that were not included in the video, I came to the conclusion that at a temperature of 600-700 degrees, the linear dimensions of this steel change sharply in relation to the usual one and the already welded seam breaks. I tried to lay transition materials, nothing helped. Forging methods stimulating the upward diffusion of carbon were used to create a damask structure. The resulting hardness is about 57 units according to Rockville. Barrel: 30-mm aircraft gun GSh-30-1 from Su-27, bent when a downed aircraft fell. There is almost no information about the steel, except that heavenly steel alloyed with niobium is used. Thanks for your support in the comments. Today is the 1299th day of the war.

Topics already covered: 1. Why do I add pepper to container Damascus steel. 2. What do I sprinkle? Flux and its composition. 3. How do I remove the container from the workpiece (container Damascus steel). 4. Why am I drilling a hole in a container. 5. Why do I sweep away the dross from the anvil with my hand. 6. Why do I first forge some blanks on a tree. 7. In what and why do I soak the blank before forging. 8. In which granules do I place the workpiece after forging. 9. What kind of white powder do I pour into the container. 10. In what liquid do I develop the pattern on the blade. Channel Support:   / shurap   My site: https://sites.google.com/site/damasks...
