According to different corrosion degree of bucket tooth pin, we can divided its abrasion damage into three different grades

　　Generally speaking, according to the different corrosion degree of the bucket tooth pin products, the final test results about the abrasion damage of the tooth pin can be divided into three different grade too, for example, if the abrasion damage grade is the first grade, then it means this bucket tooth pin belongs to the new tooth pin products, which don’t has the abrasion process before.

　　If the abrasion damage grade of the bucket tooth pin is middle grade, then we can calculate that the total abrasion length of the tooth pin would be six millimeters, and the average length of the abrasion surface is about twenty two millimeters. And if the bucket tooth pin has the three grade abrasion damage, then the total abrasion length of the tooth pin can be equal or over fifteen millimeters, and the average length of the abrasion surface is equal or over thirty millimeters. If the bucket tooth pin is used in the mine industry, then the total length of the abrasion surface would be half of the total length of the tooth pin.
