Common questions
What types of steel can I heat treat in the KM18 Pro?
The KM18 Pro reaches 2350°F, making it suitable for virtually all knife steels including high-carbon steels (1095, 1084, 5160), stainless steels (440C, AEB-L, CPM-154), tool steels (D2, A2, O1), and Damascus composites. This temperature range covers the hardening requirements for both simple carbon steels and complex stainless alloys. The dual chambers allow you to harden in one chamber while tempering in the other for efficient workflow.
Do I need a gas inlet port for atmosphere control?
For most knife heat treating, the standard oven without atmosphere control is sufficient. However, if you're working with reactive stainless steels that require scale-free finishes or need to prevent decarburization on high-carbon blades, you can add an optional gas inlet port for argon or nitrogen atmosphere. Many knife makers achieve excellent results without atmosphere control by using anti-scale compounds or foil wrapping.
What controller comes standard and how does it work?
Each chamber includes its own digital controller that allows you to set precise target temperatures and hold times. The controllers operate independently, so you can run different heat treat schedules simultaneously—for example, hardening at 2000°F in one chamber while tempering at 400°F in the other. The rapid heating ceramic fiber construction means you reach set temperatures quickly, reducing wait time between cycles.
How does the KM18 Pro compare to single-chamber knife ovens?
The dual-chamber design doubles your production capacity and workflow efficiency. You can process two batches simultaneously at different temperatures, or dedicate one chamber to hardening and one to tempering for streamlined production. The 18-inch chamber length accommodates full-size blades and swords, while the independent controls give you flexibility that single-chamber ovens can't match. For professional knife makers or serious hobbyists, the KM18 Pro eliminates production bottlenecks.
Why do I need to buy from an authorized Paragon dealer?
Paragon's one-year warranty is only valid when purchased through authorized dealers like Peach State Pottery, and the warranty must be registered within 30 days of delivery. Authorized dealers provide proper technical support, installation guidance, and access to factory-trained service. Purchasing from unauthorized sources voids your warranty and leaves you without manufacturer support for this specialized heat treating equipment.
