The greatest changes in properties occur when the metal is cooled to very low temperatures near the boiling points of liquid hydrogen and helium. However, even at less severe subzero temperatures encountered in arctic regions, where the temperatures may fall to as low as -70°C (-95°F), carbon steels become embrittled.
