摘 要：
Adopting the method of contrast test, 6 different temperature was set from 200 ℃ to study the wear-resisting steel after welding tempering temperature. The results showed that the composite wear-resisting steel changes in the aspects of microscopic metallographic organization, surface hardness, tensile properties, impact performance, and it is advisable to tempering temperature 350℃ after welding.
