heat-treating process where carbon is introduced into a solid iron alloy by heating above transformation temperature range while in contact with a carbonaceous material (solid, liquid, or gas form of carbon). Usually quenched to produce a hardened outer s

n: test made to verify that each product vaporises within the specified proper temperature range.

heating a steel pipe to a temperature above the alloy transformation temperature range and holding at the temperature for long enough to remove stored stressed from handling, forming or other fabrication.

n: the range of ambient temperatures, given by their extremes, within which a transducer is intended to operate.
