Common questions
What types of steel can I heat treat in the KM24 Pro?
The KM24 Pro fires to 2350°F, making it suitable for hardening and tempering high-carbon steels (1095, 1084, 1075), stainless steels (440C, AEB-L, 154CM), and tool steels (D2, A2, O1). The extra-wide chamber lets you process larger batches of the same steel in one cycle.
Do I need a gas inlet for protective atmosphere?
A gas inlet port is optional but recommended for professional bladesmiths who want to prevent oxidation and decarburization during the hardening process. The port allows you to introduce argon, nitrogen, or other protective gases into the chamber. It's available as an optional accessory and can be installed at time of purchase or added later.
What controller comes standard with the KM24 Pro?
The KM24 Pro Double Barrel includes a Sentinel touchscreen controller with 3-zone control and programmable temperature ramps and holds. You can create multi-step heat treating profiles for precise control over hardening, soaking, and tempering cycles. For advanced features like Wi-Fi monitoring and expanded profile storage, the Genesis touchscreen is available as an upgrade.
How does the KM24 Pro compare to single-chamber knife ovens?
The Double Barrel has one chamber that is much wider than the standard KM24 Pro, so you can heat treat more blades per load. It is one chamber with one 3-zone controller, so everything in a load runs the same program while the three zones keep heating even. The ceramic fiber construction heats faster than brick ovens, reaching 500°F in minutes rather than an hour or more.
Do I need to purchase this through an authorized dealer for warranty coverage?
Yes. Paragon's one-year limited warranty is only valid on kilns purchased through authorized dealers like Peach State Pottery. The warranty must be registered within 30 days of delivery. Unauthorized dealers, used equipment, and private-party sales are not covered under manufacturer warranty.

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.
