Perfectly flat. As pertaining to sheet, strip or plate. (See
Heating metal to above the critical range and appropriately
cooling to develop the greatest possible commercial softness
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, completely annealed.
(No. 5 TEMPER) - Condition of maximum softness commercially
attainable in wire, strip, or sheet metal in the annealed state.
A method whereby the raw slit edge of metal is removed by rolling
Removal of carbon from the outer surface of iron or steel,
usually by heating in an oxidizing or reducing atmosphere. Water
vapor, oxygen and carbon dioxide are strong decarburizers. Reheating
with adhering scale is also strongly decarburizing in action.
The process of cold working or drawing sheet or strip metal
blanks by means of dies on a press into shames which are usually
more or less cup-like in character involving considerable plastic
deformation of the metal. Deep-drawing quality sheet or strip
steel, ordered or sold on the basis of suitability for deep-drawing.
(In steel making) - Removing gases from the molten metal by
means of a vacuum process in combination with mechanical action.
Allotropic modification of iron, stable above 2552°F. to
melting point. It is of body-centered cubic crystal structure.
Removal of oxygen. In steel sheet, strip, and wire technology,
the term refers to heat treatment in a reducing atmosphere, to
lessen the amount of scale. (See Controlled Atmosphere Furnaces)
Lines of markings caused on drawn or extruded products by minor
imperfections in the surface of the die.
Forming or machining a depressed pattern in a die.
A concave surface departing from a straight line edge to edge.
Indicates transverse or across the width.
A hardened and tempered spring steel strip, usually blued,
produced from approximately .85 carbon cold rolled spring steel
strip specially selected for straightness and good edges. Sometimes
hand straightened or straightened by grinding and cut to desired
lengths. This product is used in the printing trade as a blade
to uniformly remove excess ink (dope) from the rolls;
hence its name.
Reheated after hardening to a temperature below the critical
for the purpose of changing the hardness of the steel. (See Tempering)
A term given to an annealed and polished high carbon tool steel
rod usually round and centerless ground. The sizes range in round
stock from .013 to 1 ½ diameter. Commercial qualities
embrace water and oil hardening grades. A less popular but nevertheless
standard grade is a non-deforming quality. Drill Rods are used
principally by machinists and tool and die makers for punches,
drills, taps, dowel pins, screw machine parts, small tools, etc.
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.
The property of metals that enables them to be mechanically
deformed when cold, without fracture. In steel, ductility is
usually measured by elongation and reduction of area as determined
in a tensile test.
The trade name applied to the first aluminum-copper-magnesium
type of age-hardenable alloy (17S), which contains nominally
4% Cu, ½ % Mg. The term is sometimes used to include the
class of wrought aluminum-copper-magnesium alloys that harden
during aging at room temperature.
