	Ductile cast iron pipe	Grey iron pipe	Steel pipe
Tensile strength(Mpa)	≥420	150--260	≥400
Yield strength(Mpa)	≥300	200--360	No confirmation
Bending strength(Mpa)	≥590	Neglected	≥400
Elongation(%)	≥10	≤230	≥18
Brinell hardness(HBS)	≤230		About 140
After annealing,the microstructure of ductile cast iron pipes is ferrite and a little pearlite,possessing excellen mechanical properties.
