- Begin with your Damascus product wrapped as tightly as possible in .002 SST foil. Use double folds on all sides to ensure a tight seal.
- Preheat your furnace to austenitizing temperature – 1,925 degrees Fahrenheit.
- Place your wrapped piece in the furnace.
- Allow your furnace to cycle back up to austenitizing temperature.
- Soak your piece for 15 minutes.
- Quench in oil until it stops smoking.
- Temper twice at 350 degrees Fahrenheit for an hour each time.
- For advanced cryo hardening, quench in liquid nitrogen for 4 hours, then re-temper once at 350 degrees Fahrenheit. For more information on cryo treatment, read through this forum thread.
I purchased several beautiful blades from Jantz knife supply in the past.
My question is we lost or home and everything in it (along with all my tools and half a dozen Damascus blades that I hadn’t put handles on). How can I temper them wit a welding torch? Hate to toss them out.
Thanks for your time.
