Common questions
What steel types can I heat treat in the HS-18K?
The HS-18K reaches 2200°F, making it suitable for hardening most common knife steels including 1095, 1084, 5160, 52100, O1, W2, and 15N20. High-alloy steels like D2 and A2 can be hardened at this temperature, though some premium stainless steels requiring higher austenitizing temperatures (S30V, S35VN) may need specialized equipment. Hot Shot’s optional argon kit allows protective gas during heat treating to prevent decarburization on high-carbon steels. For tempering cycles, this oven handles all steel types from 300°F to 1000°F.
Can I introduce atmosphere into the chamber during heat treating?
Yes, with Hot Shot’s optional argon kit (sold separately), which adds the tubing, fittings and ceramic dispensing needle for protective atmosphere during heat treating. Most knife makers use argon or nitrogen to prevent oxidation and scale formation on blade surfaces during austenitizing. This is especially important for high-carbon steels that are prone to decarburization at elevated temperatures. You'll also need your own argon supply and regulator. Always ensure proper ventilation when using atmosphere gases.
What's the difference between 120V and 240V models?
The 120V model plugs into a standard household outlet, making it convenient for small shops without dedicated electrical service. However, the 240V model heats faster and maintains temperature more efficiently during extended heat treating sessions or when door is opened frequently. If you're heat treating multiple blades per day or working with larger stock, the 240V option reduces cycle times significantly. Consult with a licensed electrician to determine which voltage is best for your electrical service and production needs.
Does this oven include the digital controller and solid state relay?
Yes, the HS-18K comes standard with both a Tap&Go programmable controller and solid state relay (SSR). The SSR is critical for knife making because it extends element life and provides smoother temperature control during critical austenitizing holds. Unlike cheaper on/off controllers that cycle power abruptly, the solid state relay gradually modulates power for precise temperature maintenance within ±5°F. This precision is essential when heat treating steels with narrow hardening temperature windows.
Is my warranty valid if I don't buy from an authorized dealer?
No. Hot Shot warranties are only valid when purchased through authorized dealers like Peach State Pottery. Ovens purchased from unauthorized resellers, auction sites, or private parties have no manufacturer warranty coverage. Additionally, you must register your oven within 30 days of delivery to activate the one-year limited warranty. Authorized dealers provide proper documentation, support technical questions, and facilitate warranty service if needed.

Common questions about this kiln

Still stuck? Call or text (470) 264-3563 and talk it through with a real person.

Is freight delivery included in the price?

No. Kiln prices do not include freight, and we do not quietly build it into the product price. Freight is charged at a flat rate based on your delivery address and is shown at checkout. Liftgate service is included when it is needed, and standard delivery is curbside. You can estimate your delivered cost with the ZIP code tool above the Add to Cart button.

Can I return this kiln if it is not right?

Return requests can be submitted within 30 days of delivery. The kiln needs to be in its original packaging, in new and resellable condition, and approved before it is sent back. A restocking fee may apply. Completing the manufacturer's recommended first test firing does not by itself make a kiln non-returnable, so you can confirm it works before you commit. Full terms are on our Returns page.

What electrical supply do I need for this kiln?

The Specifications tab on this page lists this model's voltage, amperage, required breaker size and NEMA plug configuration. Most 240V kilns need their own dedicated circuit fitted by a licensed electrician, while many 120V models run from a standard household outlet. If you are unsure what your space can support, call or text (470) 264-3563 before ordering.

Does this kiln come with a warranty?

Yes. This kiln carries the HotShot Oven & Kiln manufacturer warranty. Coverage length, what is included and any registration deadline are listed in the Specifications tab on this page. We are an authorized HotShot Oven & Kiln dealer, which is a condition of warranty coverage on most kiln brands.

What comes with the kiln, and what do I need to buy separately?

The What's Included tab on this page lists exactly what ships with this kiln. Most kilns need shelves, posts and kiln wash before your first firing, and these are not always included. A vent is recommended for indoor installations. Any add-ons available for this model are shown above the Add to Cart button.
