Release time:

2024-01-12

The main components of ductile iron pipe are carbon, silicon, manganese, sulfur, phosphorus and magnesium. In the ferrite and pearlite matrix on the distribution of a certain number of spherical graphite, according to the nominal caliber and the different requirements of the elongation, the matrix organization of ferrite and pearlite proportion is different, the proportion of pearlite is generally not more than 20%, large caliber is generally controlled at about 25%. Small tensile strength:420/Mpa, small yield strength 300/Mpa, small elongation 7%.
