Analysis the ESCO bucket tooth pin from the organization aspect

　　As general, we can analysis the ESCO bucket tooth pin from the organization aspect, for example, though the organization, we can carefully check the metallo graphic phase of the ESCO bucket tooth pin, and the analysis result is that the main shape of the basis body is the thin piece shape contents and the color is the black color. But to the insert part of the ESCO bucket tooth pin, its color has two different colors, they are the white color massive parts and the black color thin piece parts, this phenomenon is very obvious.

　　If we use the micro hardness equipment to test the ESCO bucket tooth pin, we can find that away from the cross section area, the white color massive content is very abundant, and the main contents of these white color massive content is the ferrite, and the main contents of the black color thin piece shape contents is the nodular fine pearlite, or the mixed of the nodular fine pearlite and the pearlite.
