Class of iron–carbon alloys with a carbon content more than 2%.
The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing.
Chemical element with the symbol Mg and atomic number 12.
As an additive agent in conventional propellants and the production of nodular graphite in cast iron.
Keith Dwight Millis (May 20, 1915 – July 6, 1992) was an American metallurgical engineer and inventor of ductile iron.
Chemical element with the symbol Y and atomic number 39.
Yttrium has been studied as a nodulizer in ductile cast iron, forming the graphite into compact nodules instead of flakes to increase ductility and fatigue resistance.
Ductile iron pipe is pipe made of ductile cast iron commonly used for potable water transmission and distribution.
Chemical element with symbol Fe and atomic number 26.
A newer variant of gray iron, referred to as ductile iron, is specially treated with trace amounts of magnesium to alter the shape of graphite to spheroids, or nodules, reducing the stress concentrations and vastly increasing the toughness and strength of the material.
Trademark for an engineering process to make a range of cast irons produced under specific and carefully controlled conditions to precise internationally recognized specifications.
High duty flake or gray irons; high duty “nodular” or ductile iron (SG); and a group consisting of special types for applications requiring resistance to heat, wear and corrosion.
Minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig.
Directional Boring/HDD can be utilized with various pipe materials such as PVC, polyethylene, polypropylene, ductile iron, and steel provided that the pipe's properties (wall thickness and material strength) enable it to be both installed and operated (if applicable) under acceptable stress limits.
Practice of measuring water use.
Turbine meter bodies are commonly made of bronze, cast iron or ductile iron.
Type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths.
These may be ductile.
