Method of producing a cold temperature high toughness structural steel tubing
摘要:
An apparatus (10) includes a low-carbon steel tube (24). The low-carbon steel tube (24) yields plastically more than about 5% before fracturing at temperatures down to about null40null C. when stress is applied to the low-carbon steel tube sufficient to cause the low carbon steel tube to so yield.
