LT 18" Tempering Oven with Compact Chamber for Precision Stress Relief
The Evenheat LT 18 Tempering Oven is purpose-built for post-quench tempering, giving your blades the toughness and flexibility they need. With its 18″ deep chamber and shallow 4.25″ height, it’s sized to hold chef’s knives, hunters, and shop tools efficiently.
Operating up to 1200°F (650°C), this oven is ideal for tempering stainless, carbon, and specialty steels after hardening. Digital controls let you set precise soak times and temperatures, so you can count on consistent results with every cycle.
The LT 18 is designed to fit neatly on top of Evenheat’s 18″ LB, KO, and KF models or work as a standalone bench unit. Paired with smart details like a relay access port, door shield, and the Quiet Drive solid-state relay, it’s a shop-friendly solution that makes tempering safe, reliable, and simple.
