Heat Treatment of Steel

The temperature required for annealing should be slightly above the critical point, which varies for different steels. Low-carbon steel should be annealed at about 1650 degrees F., and high-carbon steel at between 1400 degrees and 1500 degrees F. This temperature should be maintained just long enough to heat the entire piece evenly throughout.

Stainless SteelsAn Introduction to Their Metallurgy and

stainless steels are almost always placed in service in the annealed condition. This means they are quenched in water or other fast cooling media from the annealing temperature (1040°C -1130°C). Thus, annealing has a different meaning than it has for carbon or low-alloy steels, which are generally slow-cooled from the annealing tempera-ture.
