Abstract

Abstract: The classification of the shovel teeth was summarized. From the different microstructures of steels for shovel teeth, the development of steels for various types of shovel teeth had been described at home and abroad, including the specific chemical composition, heat treatment, comprehensive performance and existing problems, etc. The advantages and disadvantages of austenitic wear-resistant steel shovel teeth, martensite wear-resistant steel shovel teeth, bainite wear-resistant steel shovel teeth and composite phase shovel teeth were summarized, and the problems of steels for shovel teeth in China were summarized. It can be found that the steels of the bainite structure has a broad development space.

Key words: shovel teeth material, heat treatment, microstructure, application
