In this paper, we discussed the physical properties of different metal materials under cold condition and further analyzed these properties related to high-speed railway OCS. We proposed that the cold temperature impact toughness should be the primary factor to be considered when selecting metal materials. Then, we studied steel material because its physical property had very remarkable change on the cold condition influence and drawed some conclusions Finally, some advices are given for the metal materials＇selecting on high-speed railway OCS components in extremely cold area.
