| Bright Dipping | (english) Chemical polishing of aluminum, often by treatment with a mixture of nitric acid and phosphoric acid, yielding a mirror-shiny (specular) highly reflective surface. It is almost always followed by anodizing to protect the surface and provide some choice of color. |
| Bright Drawing | (english) The process of drawing hot rolled steel through a die to impart close dimensional tolerances, a bright scale free surface and improved mechanical properties. The product is termed bright steel. |
| 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. |
| Bruise | (english) A mark transferred to the strip surface from a defective process roll. Similar to dent or punchmark. |
| 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. |
| Burn | (english) 1) Process of cutting metal by a stream of fuel and oxygen, 2) to permanently damage a metal or alloy by heating to cause either incipient melting or intergranular oxidation. |
| Burr | (english) The very subtle ridge on the edge of strip steel left by cutting operations such as slitting, trimming, shearing, or blanking. For example, as a steel processor trims the sides of the sheet steel parallel or cuts a sheet of steel into strips, its edges will bend with the direction of the cut. |
| Burr Mashers | (english) Devices used to remove build up on edge of strip after the slitting process. |
| Busheling | (english) A widely traded form of steel scrap consisting of sheet clips and stampings from metal production. Bushel baskets were used to collect the material through World War II, giving rise to the term. |
| By Coil | (english) Selling term which refers to product sold in the form of a coil vs. cut plate. "Bi Coil" is also used in production to refer to coils vs. cut plate |
