ABSTRACT:
Wear resistors adapted for use in wear parts comprising steel castings for replaceable attachment to snow plows, road machinery equipment, agriculture, and construction excavator teeth. The wear castings provide a replaceable member for wear affected parts of equipment used for cutting, scraping, digging, plowing, etc. Each replaceable wear part can comprise a hard, impact resistant metal of high shear strength having at least one cavity filled with an abrasion resistant weldment or resistor. The abrasion resistant weldment can be placed proximal to the wear edges or wear surfaces of the expendable and replaceable wear parts.
