Hot Shot Knife Oven HS-1200K
The HS-1200K is a single-chamber 240V heat treat oven designed specifically for knife makers, blacksmiths, and small-scale heat treating operations. With a 12″ deep by 10″ wide by 10″ high chamber reaching 2200°F, this front-loading oven handles blade hardening, tempering, and annealing for carbon and tool steels. Hot Shot ovens include solid state relays as standard equipment for precise temperature control and extended element life.

Common questions
What steel types can I heat treat in the HS-1200K?
The HS-1200K reaches 2200°F, making it suitable for hardening and tempering most carbon steels (1084, 1095, 15N20), tool steels (O1, A2, D2), and many stainless steels (440C, AEB-L). For Damascus or pattern-welded steels, the chamber accommodates billets up to 10″ wide. High-alloy steels requiring austenitizing temperatures above 2100°F (such as CPM-154 or S30V) will reach their critical temperature range. Consult your steel supplier's heat treat specification sheets for exact hardening temperatures and soak times.
Can I add atmosphere capability for scale-free heat treating?
Yes. The optional atmosphere port kit allows you to introduce inert gas (argon or nitrogen) during the heat treat cycle to prevent oxidation and scale formation on blades. This is especially valuable when hardening stainless steels or when you want to minimize surface cleanup before grinding. You'll need to source your own gas supply and regulator—most knife makers use a standard welding gas cylinder with a low-pressure regulator. The oven is not designed for explosive or flammable atmospheres.
Does the standard controller handle complex tempering cycles?
The included digital controller supports ramp/hold programming, which covers most heat treat operations including multi-stage tempering. You can program a ramp to your hardening temperature, hold for the required soak time, then cool and ramp back up for tempering. For knife makers who run frequent batches with different steel types or need to store dozens of custom programs, the Genesis touchscreen upgrade offers expanded memory and a more user-friendly interface for cycling between recipes.
What's the advantage of the solid state relay being included standard?
Hot Shot includes SSRs as standard equipment because they significantly extend element life and provide smoother temperature control compared to mechanical contactors. SSRs eliminate the clicking and arcing associated with relay switching, reduce voltage spikes that can damage heating elements, and allow for more precise temperature modulation. For a heat treat oven that cycles frequently to different temperatures, this translates to lower long-term operating costs and more consistent results across your blades.
Is the HS-1200K covered by warranty if I buy from Peach State Pottery?
Yes. Peach State Pottery is an authorized Hot Shot dealer, so your HS-1200K is covered by the manufacturer's one-year limited warranty. You must register the oven within 30 days of delivery to activate coverage. Warranty is only valid on units purchased through authorized dealers—purchasing from unauthorized resellers or used equipment voids manufacturer support. Contact us if you have questions about your warranty registration or need service assistance.
