The effects of pa tenting process on high carbon steel and alloy steelare analyzed in detail. The drawing mechanism ofpearlite steelwire is inquired. It is pointed out that the slice distance ofpearlite and dislocation are relative toworking hardening, strain ageing can alter the mechanical property. In order to heighten the strength of steelwire, should develop high carbon Cr alloy wire rod or B alloy wire rod.
