brass | harden | heat treating I am wondering if brass can be heat-hardened. I've made a brass cuff that is a bit too flimsy, and would like to harden it without changing the surface. I've already tried tumbling with steel shot for about 5 hours, but it did not seem to harden it at all. Any suggestions/ideas? I've searched the web and ganoksin, and the answer seems to elude me. For Gimperfi. Some fun with steel, a hamon, and heat treating

Knife-makers blade | custom knife | hardening | heat treating | knife | visible hamon Hey Gimperfi, I mentioned some of the fun you can have with differential hardening, so thought I'd share some pics. This started out as a dull old Nicholson file. I annealed it, then ground it, packed the spine with Satanite refractory clay, and hardened it, creating a differential temper (soft at the spine, super hard at the edge), as well as a hamon, the traditional Japanese visible hardening line. Thought maybe the pics would inspire you to upgrade your rig and get into heat treating. The clay coating: tempering stainless spring steel

heat treating | kiln | tempering I am hoping to start working with stainless spring steel soon but had a question about heat treating it. Annealing is not a problem, but when doing some research I saw that you need to bring the kiln to 900 degrees and maintain that temperature for a specified time. Does anyone know whether you put the piece in the kiln then bring it up to temp, or do you allow the kiln to pre-heat to the specified temp then insert the piece?  |
