Dead Soft Annealing:

The heating of metal to above the critical range and appropriately cooling to develop the greatest possible commercial softness or ductility.

Dead Soft Steel:

A steel normally made in the basic open-hearth furnace or by the basic oxygen process with carbon less than 0.10% and manganese in the 0.20%-0.50% range and which is completely annealed.

Dead Soft Temper:

Condition of maximum softness commercially attainable in wire, strip, or sheet metal in the annealed state.

Deburring:

A method whereby the raw slit edge of metal is removed by rolling or filing.

Decarburization:

The removal of carbon from the outer surface of iron or steel, usually by heating in an oxidizing or reducing atmosphere.

Deep Drawing:

The process of cold working sheet or strip metal blanks by means of dies on a press into shapes, which are usually cuplike in character and involving considerable plastic deformation of the metal.

Drill Rod:

An annealed and polished high alloy steel rod that is usually round.

Dry Rolled Finish:

A finish obtained by cold rolling on polished rolls without the use of any coolant or metal lubricant, material previously plain pickled, giving a burnished appearance.

Ductility:

The property of metals that enables them to be mechanically deformed when cold without fracturing.
