| C |
| CAKE A copper ingot rectangular in cross section intended for rolling. |
| CAMBER OR BOW Edgewise curvature. A lateral departure of a side edge of sheet or strip metal from a straight line. |
| CAMERA SHUTTER STEEL Hardened, tempered and bright polished extra flat and extra precision rolled. Carbon content 1.25-Chromium .15. |
| CAPPED STEEL (See Bottle Top Mold.) |
| CARBIDE A compound of carbon with one or more metallic elements. |
| CARBON (Chemical symbol C] Element No. 6 of the periodic system; atomic weight 12.01; has three allotropic modifications, all non-metallic. 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. |
| CARBON FREE Metals and alloys which are practically free from carbon. |
| CARBON RANGE In steel specifications, the carbon range is the difference between the minimum and maximum amount of carbon acceptable. |
| CARBON STEEL Common or ordinary steel as contrasted with special or alloy steels, which contain other alloying metals in addition to the usual constituents of steel in their common percentages. |
| CARBURIZING (Cementation.) 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. |
