We are committed to manufacturing the most durable track chains suitable for various complex construction environments. While the market primarily uses materials like 40Mn2 and 40MnB, heavy equipment used in mining requires greater wear resistance and strength. Therefore, we have chosen 35MnB material from Hangzhou Steel and Baosteel to enhance wear resistance. These chains can achieve a hardness of 47-55 and a depth of 5-8.
