Boron (chemical symbol B) (english) Element N. 5 of the periodic system. Atomic weight 10.82. It is gray in color, ignites at about 1112 (degrees) F. and burns with a brilliant green flame, but its melting point in a non-oxidizing atmosphere is about 4000 (degrees) F. Boron is used in steel in minute quantities for one purpose only- to increase the hardenability as in case hardening and to increase strength and hardness penetration.
Brake (english) A piece of equipment used for bending sheet; also called a bar folder. If operated manually, it is called a hand brake; if power driven, it is called a press brake.
Breakout (english) An accident caused by the failure of the walls of the hearth of the furnace resulting in liquid iron or slag (or both) flowing uncontrolled out of the blast furnace.

Bundle (english) Specific number of sheets which equals 1 unit of production. Number is determined by multiplying sheets/Packages/BUNDLE. For example, an order calls for 112 sheets/package. According to the maximum height allowed for a lift. Therefore, multiplying 15 packages X 112 sheets 3D 1680 sheets/bundle.
Bust Coil (english) Coils removed from the off-gauge reel. The BUST (build up side trimmer) coil contains defects (gauge variation and quality defects) and off-spec widths.

Acceleration: (english) A vector quantity equal to the rate that velocity changes with time.
Component (of a vector): (english) Any vector can be expressed as a collection of vectors whose sum is equal to the original vector. Each vector in this collection is a component of the original vector. It is common to express a vector in terms of components which are parallel to the x and y axes.
