Knife Steel Heat Treat Calculator
Free reference tools for bladesmiths and knifemakers: look up a heat-treat schedule for a common blade steel, convert a forge or temper color to an approximate temperature, and compare steels side by side. No signup, nothing uploaded — everything runs in your browser.
Heat-treat schedule lookup
Pick a steel → austenitizing temperature, quench medium, and temper guidance.
Forge & temper color guide
Convert a forging or tempering color to an approximate temperature, or the reverse.
Blade steel reference chart
Sourced composition, category, and heat-treat notes for seven common knifemaking steels, side by side.
These are general starting references (see each tool for sources), not a substitute for your own steel supplier's datasheet — and color judgment by eye is never as precise as a pyrometer or thermocouple.
