Get a Gas Injection Flow Meter (GIFM) and Solenoid Kit
Achieving a clean, scale-free blade finish during heat treatment isn’t just about aesthetics—it’s about quality, consistency, and minimizing post-processing time. The Gas Injection Flow Meter (GIFM) is a trusted tool among professional bladesmiths and heat treaters for precisely that reason.
Minimize Scale, Maximize Results
During high-temperature heat treating, oxygen in the kiln chamber reacts with the steel surface, producing unwanted oxidation scale. Traditionally, this has been mitigated using stainless steel foil wrap—a solution that works, but comes with added cost, time, and waste.
With the GIFM installed, you can introduce an inert gas like argon or nitrogen directly into the firing chamber. This displaces oxygen and significantly reduces oxidation, helping you:
Eliminate or reduce the need for stainless foil
Retain sharper blade edges and crisper grind lines
Improve consistency in finish and minimize cleanup
Create a cleaner working environment
Take control even further with the Solenoid Valve Kit, which works in tandem with the GIFM. This upgrade lets you:
Automate gas flow by turning it on/off at specific stages of the firing process (per segment)
Ensure gas is flowing only when needed—saving resources and increasing safety
Achieve repeatable, precision-controlled atmospheres in your heat treating cycles
Perfect for advanced users and production settings, this upgrade transforms your kiln into a highly efficient and customizable heat treating system.
This system has been field-proven by bladesmiths, metalworkers, and heat treatment professionals who demand the best finish and tightest process control.
Whether you’re eliminating scale on high-carbon steel or refining your results with stainless alloys, the GIFM with optional solenoid valve gives you an edge—literally and figuratively.
