1095 Not Annealing
Bill Reinicke posted a topic in Heat Treating by AlloyI am a new knife maker. I got ahead of myself and heat treated my blades before I drilled holes for the scales. I did a great job heat treating but now I can't anneal the blades to be able to drill them. I have tried several normalizing sessions. I have taken the blades to critical temp an allowed to cool very slowly. It doesn't seem to matter what I do, it almost seems like these blades are only getting harder. I am using a forge so my temps are estimations at best and am mostly going by sight and color of metal. I took a few of the blades and let them soak at critical temp for about 15-20 minutes before letting them slowly cool. The blades seems even harder. The file still skates across it like it did after the quench for heat treating. Any ideas?
Joshua States posted a topic in Heat Treating by AlloyI did a site search on Google foor this topic and only found one discussion that didn't yield much, so I'm asking again. I recently started using 1095 in my Damascus and I have this multi-bar pattern all welded up and ready to accordion cut. I normalized 3X and set the bar to anneal. The bar measures 1-1/2" x 7/8" x 8" Into the Paragon: Ramp up to 1450 @ 250 degrees per hour, hold for 1.5 hours Ramp down to 1200 @ 100 degrees per hour hold for 1 hour Turn off oven. This would not cut on the bandsaw (at least not very easily, it killed two blades before cutting 6 lines each about 3/4" long) A quick call to Hancock, and we decided to try it again. So, I put it back in to the paragon. Ramp up to 1350 @ 200 degrees per hour, hold for 2 hours Ramp down to 1250 @ 100 degrees per hour, hold for 2 hours Shut the oven off. This is even harder than the first one. It is eating bandsaw blades before making a single cut. Any ideas or suggestions? Here is the bar:
