The plain carbon steel "CK45" has relatively well mechanical and metallurgical properties and low cost. The purpose of this research was the property evaluation of this steel on abrasive wear and impact for using in plows and other tillage tools. Tillage tool should resist in abrasive wear and impact simultaneously. Several heat treatments were done on specimens of this steel. A standard test device for abrasive wear "Standard Test Method for Conducting Wet Sand/Rubber Wheel Abrasion Tests, G105-89" was made. This device and standard charpy test apparatus determined the abrasive and impact resistance, respectively. Results showed that the impact and abrasive resistance of this steel can be improved by simple heat treatment and used properly for tillage tools.
