Common questions
What types of steel can I heat treat in the KM18 Pro?
The KM18 Pro reaches 2350°F, making it suitable for heat treating most common knife steels including 1095, 1084, 5160, 52100, O1, A2, and many stainless steels like 440C and AEB-L. High-alloy stainless steels requiring temperatures above 2000°F (like S30V, S35VN, or CPM steels) can be hardened, though you may need atmosphere control for optimal results. Carbon and low-alloy steels that harden between 1450-1550°F are ideal for this oven.
Do I need a gas inlet for atmosphere control?
Most carbon steel heat treating can be done successfully in an air atmosphere without gas inlet. However, if you work with high-alloy stainless steels or want to minimize decarburization and scale formation on any steel, adding an optional gas inlet port for inert atmosphere (argon or nitrogen) or reducing atmosphere gives you better control over surface finish and edge retention. Many bladesmiths start without atmosphere control and add it later as their work advances.
What controller comes standard with the KM18 Pro?
The KM18 Pro includes a programmable digital controller as standard equipment, allowing you to set precise temperatures and hold times for hardening and tempering cycles. For bladesmiths who want more advanced programming—such as multi-step ramp/soak profiles for complex heat treating schedules or data logging for production work—the Genesis touchscreen upgrade is available and offers significantly more control and documentation capability.
How does the KM18 Pro compare to brick kilns for knife making?
The ceramic fiber construction heats up to 500°F in just minutes compared to 45-60 minutes for traditional brick kilns, saving significant time and energy. The fiber insulation also cools faster, allowing you to run more heat treating cycles per day. The wavy surface-mounted elements last longer than elements in brick kilns because they dissipate heat more efficiently. The trade-off is that fiber kilns require more careful handling—avoid touching the fiber walls—while brick kilns are more durable for rough shop environments.

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.
