Evenheat · Salt Bath Oven · Molten Salt Hardening Evenheat Salt Bath - 718 Model EH-SB-718 · 240V · 7″ W × 7″ L × 18″ D · 2000°F max The 718 hardens steel by immersing the blade in a bath of molten salt instead of heating it in open air. Once submerged, the piece reaches hardening temperature almost immediately and soaks in an oxygen-free environment with tighter, more uniform heat than an air oven can match. The 718 steps up to an 18″-deep pot for full-length blades, and operates from a friendly 240V, 20A circuit rather than a heavier 30A service.
Max Temp2000°F (1093°C)
Chamber7″ W × 7″ L × 18″ D
Voltage240V, 18A
Salt Pot Capacityup to 5.5″ OD, 25″ deep
Key features
Grounded Salt PotStainless salt pot is fully grounded with thermocouple protection built in, a critical safety feature when working with electrically conductive molten salt.
Triple Thermocouple Safety SystemImmersion, chamber, and over-temperature thermocouples work together to monitor the bath from three angles and shut down safely if any reading goes out of range.
Stainless Steel Drip ShieldsCatch and contain any salt splash or drip around the pot opening, keeping the surrounding cabinet and floor clean.
Sectional Chamber DesignThe heating chamber is built in serviceable sections, so element or insulation maintenance doesn't require replacing the whole unit.
Swing-View Control EnclosurePivoting control housing lets you angle the display for programming, then lay flat to monitor bath temperature from across the bench.
Quiet Drive Solid State RelayZero moving parts and up to 60 firings per second, holding tight temperature control on a molten bath where consistency directly affects hardness.
Optional accessories
Loud Alarm (80dB)Optional wired alarm output for cycle-complete or over-temperature alerts, audible from across a noisy shop.
Spare Salt PotKeep a second pot on hand so a pot due for cleaning or replacement never takes the oven out of service.
Replacement Thermocouple SetSpares for the immersion, chamber, and over-temperature probes keep the triple safety system intact without a service delay.
Quench Tongs & BasketPurpose-sized tongs and a dip basket for pulling blades cleanly from the molten bath for transfer to quench.
Controller upgrades
TAP Touchscreen with Salt Bath Software — SDS IndustriesStandard Equipment
Every 718 ships standard with the TAP touchscreen running Evenheat's dedicated salt bath software — this isn't an upgrade on salt bath models, it's how the bath's triple thermocouple system and safety interlocks are managed. You still get full remote monitoring and program logging from your phone.
  • Unlimited programs and firing steps
  • TAP mobile app — monitor from your phone
  • Push notifications when firing completes
  • Adjust temp or add time mid-cycle
  • Auto-updates over Wi-Fi
  • Firing logs and maintenance schedules
Genesis Spark — Bartlett InstrumentsAlternate Option
Genesis Spark is available as an alternate controller on request, but most shops keep the standard TAP salt bath software since it's purpose-built for the triple thermocouple monitoring a molten salt bath requires. Ask us before ordering if you specifically need Genesis Spark.
  • 30 programs × 32 segments each
  • 3.2″ color touchscreen display
  • Wi-Fi for remote updates and diagnostics
  • Ramp/hold and preset modes
  • Preheat capability built in
  • Adjust firing in real time
Common questions
What is salt bath hardening and why use it over an air oven?The blade is submerged in molten salt rather than heated in air. Because the salt is already at temperature, the steel comes up to heat almost instantly and soaks in a consistent, oxygen-free environment — which means less scale, less decarburization, and more even hardness than many air ovens can deliver.
What kind of salt do I need, and is it dangerous?Evenheat salt baths run standard neutral hardening salts sold by bladesmithing and heat-treat suppliers. Molten salt is a serious hazard if mishandled — splash and steam-explosion risk from wet steel or tools is real — so proper PPE, dry tongs and workpieces, and following Evenheat's operating guidance are non-negotiable.
How is the 718 different from the other Evenheat salt bath sizes?The 709 is a compact 120V unit sized for folders and short blades. The 718 steps up to an 18″-deep pot on a 240V circuit for full-length blades, and the 818 adds both depth and pot diameter on the same 240V service for the largest work — Evenheat's best seller in the lineup. Pick based on the longest blade or largest cross-section you regularly harden.
Do I have to buy the TAP salt bath controller, or can I skip it?TAP with dedicated salt bath software ships standard on every model — it isn't an optional upgrade here because the triple thermocouple safety system is built around it. A Genesis Spark alternate is available on request; ask us before ordering.
