CARBON STEEL :
Steel which derives its properties from various percentages of carbon without any great amount of other alloying elements.
A case hardening process by which carbon alone is added to a limited or specified penetration by heating steel below its melting point in contact with carbonaceous solids, liquids, or gases.
The surface area of an iron-base alloy whose carbon content has been increased substantially by case hardening.
CASE HARDENING :
Carburizing and subsequently hardening by suitable heat-treatment, all or part of the surface portions of a piece of iron base alloy.
Removing seams and other surface defects from steel by means of hand or power chisels.
CLEAVAGE PLANE :
Planes along which crystals break more easily.
Reducing ingots to blooms by rolling or forging.
COGGING HAMMER :
Forging hammer for reducing ingots to blooms.
COLD SHORTNESS :
The characteristic of metals that are brittle at ordinary or low temperatures.
COLD SHUT :
A place in metal where two portions of the metal in either a molten or plastic condition have come together but have failed to unite into a solid mass.
COLD WORKING :
The operation of forming the metal, without the application of heat, by rolling, hammering, drawing, pressing or other means to obtain accurate size, fine finish or increased strength.
Pipe serving as a duct for electrical wiring; usually supplied in ten-foot lengths, with plain ends or threaded and coupled. The pipe used is normally galvanized, slightly larger than standard weight with a smooth inner surface. However, the term "conduit" may refer to pipe for uses other than electrical.
The interior portion of an iron-base alloy whose chemical composition has not been substantially changed as the result of case hardening.
The defective ends of a rolled or forged product which are cut off and discarded.
CUP FRACTURE :
A type of fracture in a tensile test specimen which looks like a cup having the exterior portion extended with the interior slightly depressed.
Surface hardening of an iron base alloy article or portion of it by heating at a suitable temperature in contact with a cyanide salt, followed by quenching.
