The microstructures and the tensile and fatigue properties of the domestic YUS110 and the imported SUS316L stainless steel wire rods were studied.

In order to detect the carbide network in high carbon hypereutectoid steel wire rods accurately, two kinds of detection method of the carbide network are compared.

Higher content of nitrogen is benefit for increasing strength and toughness for V-N micro-alloyed hard wire rods steel.
