Abstract
The flaring cracks and the hardness accumulation during processing procedure of thin-walled small-diameter stainless steel tube were analyzed by optical microscopy, tensile testing machine and hardness tester. The results show that there is higher hardness and smaller grains in the stainless steel tube with flaring cracks, and the grains is much more different in size; during processing procedure, the hardness is increasing linearly with the smaller of tube diameter.关键词
