Heat Treating Steel ReferenceTable
Key benchmarks for heat treating steel.

Forge ZoneStandard
Keep hot work area clear of water on floor — steam explosions.
Critical Temperature
Use a magnet — when steel stops being magnetic, it has reached critical temperature (1420°F for 1080).
Temper Colors
Watch oxide colors: straw (400°F) for edges, blue (600°F) for springs.
Decarburization
Minimize forge time at high heat to prevent surface carbon loss.
Safety Notes
- Never quench hot steel in water on the forge floor — steam explosions can cause severe burns.
- Install CO monitoring and keep a fire extinguisher rated for Class A fires within reach of the forge.
