The diagram, which is not to scale, is a composite of various designs in the late steam era. Some components shown are not the same as, or are not present, on some locomotives – for example, on smaller or articulated types. Conversely, some locomotives have components not listed here.
An iron roughneck is a piece of hydraulic machinery used to "handle" (connect and disconnect) segments of pipe in a modern drilling rig. [1] The segments can be manipulated as they are hoisted into and out of a borehole .
Steel is between 0 and 2.06 mass percent of carbon. Cast iron is between 2.06 and 6.67%. Black lines indicate the metastable Fe/Fe3Cphase, red is the stable Fe/Carbon phase This diagram is for illustrative purposes only, and is not thermodynamically accurate.
Iron roughneck is also a specialized equipment used in oil drilling operations. [1] Whether the pipe is being fed into the wellbore or it is being taken out, the iron roughneck uses a rotary table and torque wrench(es) to make up or break down the pipe. [2] In Canada on land-based rigs, the term roughneck refers to the floorhand. [citation needed]
Cementite forms directly from the melt in the case of white cast iron. In carbon steel, cementite precipitates from austenite as austenite transforms to ferrite on slow cooling, or from martensite during tempering. An intimate mixture with ferrite, the other product of austenite, forms a lamellar structure called pearlite. The iron-carbon phase ...

Low-pressure phase diagram of pure iron. BCC is body centered cubic and FCC is face-centered cubic. Iron-carbon eutectic phase diagram, showing various forms of Fe x C y substances. Iron allotropes, showing the differences in structure. The alpha iron (α-Fe) is a body-centered cubic (BCC) and the gamma iron (γ-Fe) is a face-centered cubic (FCC).
Duluth and Northeastern 28 (also known as Duluth, Missabe and Iron Range 332) is a preserved 2-8-0 "Consolidation" type steam locomotive built in 1906 by the Pittsburgh Works of American Locomotive Company (ALCO) in Pittsburgh, Pennsylvania. [1]
