DB80-DN2600 Ductile Cast Iron Pipe

Home > 2 st2


 1.Ductile iron owes its remarkable mechanical properties to the spheroidal shape of its graphite:

tensile strength,

impact resistance,Alloy steel pipe

high elastic limit (yield strength),

good elongation.

These properties are further enhanced by control of the chemical analysis and heat treatment of the metal matrix.

 |API steel pipe|

2. Ductile iron maintains the traditional qualities of cast irons, resulting from the high carbon content:

compression strength,

castability,

abrasion resistance,ERW steel pipe|

machinability,

fatigue strength.
