Heat Treating Foil – (300 mm wide, 0.05 mm thick – sold per linear meter)

Stainless steel foil for heat treatment. This foil allows you to wrap blades or other components during the heat treating process, protecting their surface from contamination, oxidation, and discoloration. Ideal for applications where a clean, precise finish is essential.
• Width: 300 mm
• Thickness: 0.05 mm
• Minimum order: 1 linear meter

Why use heat treating foil (often stainless or heat-resistant steel) for blade hardening?
✔ Prevents surface oxidation and decarburization
✔ The foil seals the blade from oxygen at high temperatures
✔ Prevents deep oxide layers (which can turn black or grey after quenching)
✔ Maintains the blade’s carbon content – ensuring hardness and wear resistance

Less post-processing
✔ No rough oxidation means less grinding and polishing after heat treatment
✔ Saves time and reduces tool wear

Cleaner working environment
✔ The foil traps contaminants and oxide dust – keeping your furnace cleaner inside

Blades heat treated in foil often yield more consistent results by minimizing external factors such as oxygen and gas flow.
