A lateral departure of a side edge of sheet or strip metal from a straight line. Carbon content 1.25, Chromium .15. A compound of carbon with one or more metallic elements. Carbon is preset in practically all ferrous alloys, and has tremendous effect on the properties of the resultant metal.
Carbon is also an essential compound of the cemented carbides.
Its metallurgical use, in the form of coke, for reduction of oxides, is very extensive. In steel specifications, the carbon range is the difference between the minimum and maximum amount of carbon acceptable. Adding carbon to the surface of iron-base alloys by absorption through heating the metal at a temperature below its melting point in contact with carbonaceous solids, liquids or gasses. The oldest method of case hardening. A term implying a lack of straightness as in a coil set.
