9CrSi Hardware Tool Steel Bar


9CrSi is a commonly used low alloy tool steel, with high hardenability and hardenability, and high tempering stability. It can be used to manufacture tools with complex shapes, small deformation, high wear resistance and low-speed cutting, such as drill bits, thread tools, reamers, die, tap, roller and roller.
