"Wear-resistant industry is an immortal industry," said Chen Zeng, chairman of the company. Wear-resistant products range from carbon steel balls to low chromium balls and then to high chromium balls, and the product specifications are getting smaller and smaller until there is no development trend of media or diversified media. However, there is no substitute on the market at present. In addition, in the second quarter of this year, the government's policy of investing 4 trillion yuan to stimulate domestic demand achieved initial results, infrastructure construction increased, and the demand for cement, coal and electricity increased, which also promoted the good development momentum of the wear-resistant materials market.
