Stumbled across this in the never-ending discussion re dry burning coils. Thought it interesting.
"The only concern is Cr(VI). As was mentioned many times we need temperatures of welding (melting) to get some Cr(VI) from stainless steel. Melting point of SS316L is 2540-2630° F (1390-1440° C). You may want to look on a color chart of hot metal color to determine a temperature of your coil."
How to tell what temperature a glowing object (metals) might be:
It doesn't really matter what the emitter is...stainless steel, cast iron, tungsten in your light bulb, the temps are about the same for a given color. Generally accepted colors/temps are:
