Blanking

(english) An early step in preparing flat-rolled steel for use by an end user. A blank is a section of sheet that has the same outer dimensions as a specified part (such as a car door or hood) but that has not yet been stamped. Steel processors may offer blanking for their customers to reduce their labor and transportation costs; excess steel can be trimmed prior to shipment.

Bamboo Grain Structure

(english) A structure in wire or sheet in which the boundaries of the grains tend to be aligned normal to the long axis and to extend completely through the thickness.

Zircon

(english) The mineral zircon silicate, ZrSiO4, a very high melting point acid refractory material used as a molding material in steel foundries.

Roller support:

(english) In two dimensions, a roller support restrains one translation degree of freedom.

Thermocline

(Environmental Engineering) The depth at which an inflection point occurs in a lake temperature profile.

Beading

(english) Raising a ridge on sheet metal

Chemical fixation (or stabilization/solidification)

(Environmental Engineering) A term for several different methods of chemically immobilizing hazardous materials into a cement, plastic, or other matrix.

Bloomery

(english) A primitive furnace used for direct reduction of ore to iron.

Stability:

(english) Stability is best defined as the opposite of instability, which is the occurrence of large structural deformations which are not the result of material failure.

Brite

(english) 1) Regular galvanize coating (not minimized spangle or JP). 2) Rolls that have no grit; smooth finish on surface of steel.

Bismuth

(english) Chemical symbol Bi. A soft, course cystalline heavy metal with a silvery white color and pinkish tinge; usually produced as a by-product of copper,leaad and other metals. Has a thermal conductivity lower than all other metals except mercury. Used as alloying agent but leading use is in pharmaceuticals.

Brown Sharp Gages

(english) A standard series of sizes refered to by numbers, in which the diameter of wire or thickness of sheet metal is generally produced and which is used in the manufacture of brass, bronze, copper, copper-base alloys and aluminum. These gage numbers have a definite relationship to each other. In this system, the decimal thickness is reduced by 50% every six gage numbers- while temper is expressed by the number of B&S gage numbers as cold reduced in thickness from previous annealing. For each B&S gage number in thickness reduction, where is assigned a hardness value of 1/4 hard.
