So far, the bucket teeth produced by domestic wholesale excavator bucket teeth manufacturers are mainly made of high-manganese steel, with some also made of alloy steel. However, it is generally believed that after solid solution treatment, high-manganese steel transforms into austenitic structure. When subjected to strong impact loads, the metal surface undergoes plastic deformation, resulting in significant work hardening within the deformed layer, which subsequently significantly increases the hardness of the surface layer. Based on practical field applications, this article introduces the application of wear-resistant surfacing welding in extending the service life of bucket teeth.
