New Build

Do you need to temper these, or is it not necessary if you aren't heating the steel up in a forge?

When I purchase the flat stock it is annealed and very soft with no real hardness. If bent it would just stay to what ever degree it was bent to.
This makes it easy to cut out the profile, drill holes and do preliminary grinding.

The steel does need to be heated in a forge or kiln to 1500° after preliminary grinding. Depending on the type steel, it is held to that
temperature for 10 to 20 minutes and then quenched in Canola oil. When cool to the touch it gets tempered at 400° in a toaster oven
for two 1 hour cycles with complete cool down to room temperature between cycles. This give a hardness of around 59 Rockwell.

The only steels I can do right now are O1, 1084 and 1095 because I only have a small forge and 1095 really needs a kiln as well. These are
all high carbon steels and will rust if not properly maintained. You must have a kiln to do work on any stainless steel.
 
Excellent information. Did you see last week's episode of F.I.F. where they made them quench in water? Lots of puckering going on for that one.

You need my oven so you can temper swords. Or cook a large pig. Dispose of bodies...

Yes, that water quench was brutal! My wife is Korean and she enjoyed that one. We watched a Korean drama about the Joseon Dynasty and the guy who finally developed that hardening process was a national hero!
The Koreans were constantly at war with China and the country was also divided into three regions that fought internally.

During the Three Kingdoms period, which lasted from 57 BCE to 668 CE, the Korean Peninsula was divided between the kingdoms of Koguryo, Paekche, and Silla. Each of these was founded as a confederation of cities after the fall of the Gojoseon kingdom.
