Ductile iron is used in many piano harps (the iron plates which anchor piano strings). Ductile iron is used for vises. Previously, regular cast iron or steel was commonly used. The properties of ductile iron make it a significant upgrade in strength and durability from cast iron without having to use steel, which is expensive and has poor ...
When the country entered the war, American began manufacturing steel parts for ships, planes, and tanks, which led to the creation of a new Special Products Division for steel products. In 1955, American shipped its first large order of ductile iron pipe. A new melting system in 1972, including the largest cupola of its kind in the world, would ...
Steel casing pipe is often specified as ASTM A-252 which is a structural grade material that does not require hydrostatic testing and the inspection requirements are not stringent and it usually costs less than other grades such as A-53, [2] A-139 or API 5L. Used natural gas line pipe is also used as casing on many projects because it is often ...

Ductile iron; Malleable iron; Wrought iron; Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight.
Gate valves are typically constructed from cast iron, cast carbon steel, ductile iron, gunmetal, stainless steel, alloy steels, and forged steels. All-metal gate valves are used in ultra-high vacuum chambers to isolate regions of the chamber. [2]
Typically metallic piping is made of steel or iron, such as unfinished, black (lacquer) steel, carbon steel, stainless steel, galvanized steel, brass, and ductile iron. Iron based piping is subject to corrosion if used within a highly oxygenated water stream. [7]
