What is the name of alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight?
Equivalent carbon content Equivalent carbon content The equivalent carbon content concept is used on ferrous materials, typically steel and cast iron, to determine various properties of the alloy when more than just carbon is used as an alloyant, which is typical. The idea is to convert the percentage of alloying elements other than carbon to the equivalent carbon percentage, because the iron-carbon phases are better understood than other iron-alloy phases. Most commonly this concept is used in welding, but it is also used when heat treating and casting cast iron. In welding, equivalent carbon content (C.E) is used to understand how the different
0-2-2 carrying axle to give better riding at speed. In the early 20th Century a number of railmotors were built by various railway companies in the UK where the locomotive section had an 0-2-2 wheel arrangement, but they were designed to operate semi-permanently coupled to a coach unit. The LSWR C14 class used a similar layout, but reversed as a 2-2-0T. Their low adhesive weight gave them a poor performance and half of them were rebuilt as the 0-4-0T S14. 0-2-2 An 0-2-2, in the Whyte notation for the classification of steam locomotives by wheel arrangement, is one that has two
