Is steel brittle or ductile? - Quora
Is steel brittle or ductile? - Quora

Steel, can be brittle and it can be ,ductile, depending on many factors that affect its microstructure: chemical composition, heat treatment etc ...

Ductile Iron | Metal Casting Resources
Ductile Iron | Metal Casting Resources

Ductile iron can be considered as steel with graphite spheroids dispersed throughout its matrix. The qualities of the metallic matrix in which the graphite spheroids are suspended have a significant effect on ductile iron’s properties, but the graphite spheroids themselves do not.

Ductile Iron Data - Section 3 - Part 1
Ductile Iron Data - Section 3 - Part 1

Ductile Iron exhibits a proportional or elastic stress-strain relationship similar to that of steel but which is limited by the gradual onset of plastic deformation. The Modulus of Elasticity for Ductile Iron, measured in tension, varies from 23.5 to 24.5 x 10 6 psi (162 - 170 GPa).

ClassNK releases guidelines for use of highly ductile steel
ClassNK releases guidelines for use of highly ductile steel

The highly ductile steel absorbs more more collision energy than conventional steel, and by applying it to hull structures, damage during collisions and groundings can be reduced. In addition, improved ductility is effective in preventing fracturing, and it is expected to ensure safety during flooding.

Ductile Iron Pipe vs. Steel Pipe - LMICO
Ductile Iron Pipe vs. Steel Pipe - LMICO

Than Steel Pipe Perhaps the most striking difference between Ductile Iron and steel pipe is the relative way their internal pressure designs are modeled. Only Ductile Iron pipe has a standardized design procedure (ANSI/AWWA C150/A21.50), and the approach in that standard is the most conservative in the piping industry. Steel
