Common questions
What types of steel can I heat treat in the KM24?
The KM24 reaches 2350°F, making it suitable for heat treating high-carbon steels (1095, 1084, 1075), tool steels (O1, A2, D2), and most popular knife-making steels. This temperature range covers austenitizing temperatures for hardening as well as lower tempering ranges. Stainless steels requiring higher temperatures (like 440C or S30V) may need specialized equipment, but the KM24 handles the vast majority of carbon and alloy steels used by custom knife makers.
Do I need a gas inlet port for atmosphere control?
A gas inlet port is optional but recommended for professional knife makers concerned with oxidation and decarburization. The optional atmosphere port allows you to introduce inert gases like argon or nitrogen, or use specialized atmosphere-control systems to protect blade surfaces during heat treating. Many makers successfully heat treat without atmosphere control by using foil wraps or anti-scale compounds, but a controlled atmosphere provides the cleanest results and eliminates surface grinding.
What controller comes standard, and are upgrades available?
The KM24 comes standard with a digital controller that offers programmable ramp/hold segments for creating precise heat treating cycles. This allows you to program specific heating rates, soak times, and cooling protocols essential for proper heat treatment. An advanced controller upgrade is available, offering additional programming segments, enhanced accuracy, and more sophisticated control features for knife makers running complex or experimental heat treating schedules.
How does the KM24 compare to other Paragon knife ovens?
The KM24's defining feature is its 24-inch chamber depth, which accommodates longer blades like swords, machetes, and oversized chef knives, or allows batch processing of multiple smaller blades. Smaller Paragon knife ovens offer similar temperature ranges and capabilities but with shorter chambers suited for standard knife lengths. The KM24 is ideal for makers who regularly work with longer blades or need higher production capacity in a single firing cycle.
Can I purchase this oven through any dealer, and how does warranty work?
Paragon warranties are only valid when purchased through authorized dealers like Peach State Pottery. Purchasing from unauthorized sellers or second-hand sources typically voids manufacturer warranty coverage. You must register your oven within 30 days of delivery to activate the one-year limited warranty. As an authorized Paragon dealer, Peach State Pottery provides full warranty support, technical assistance, and access to genuine replacement parts throughout your oven's lifetime.

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 Paragon manufacturer warranty. Coverage length, what is included and any registration deadline are listed in the Specifications tab on this page. We are an authorized Paragon 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.
