7x7x18 Salt Bath Heat Treating Oven for Uniform Hardening of Steels
The Evenheat Salt Bath 718 is designed for knife makers and machinists who need uniform hardening of longer blades and tooling. With its 7″ × 7″ × 18″ chamber, it accepts salt pots up to 5.5″ OD and ~25″ depth, giving you the capacity to process extended steels with speed and precision.
Operating up to 2000°F (1093°C), the Salt Bath 718 delivers fast, direct heat transfer while reducing scale and decarb compared to conventional air or atmosphere firing. The result is cleaner hardening, consistent results, and smoother surface finishes.
Running on a 240V, 18A circuit, the 718 is shop-friendly while packing enough chamber depth to handle blades up to 25" salt pot depth. Designed to sit safely in professional shops or dedicated knife studios, it helps you push heat treating beyond the limits of conventional kilns.
