Steel begins to glow faintly red at about *600* degrees celsius. A very slight red color may be visible below this temperature if the light is dim enough.

Steel is still relatively soft just after the red color fades but at this point it rapidly get harder as it cools.

In bright light, e.g: sunlight, the red color may not be visible until the steel is well into the "cherry red" temperature: more than 750 degrees celsius.»
