| Bright Annealing | (english) A process carried out usually in a controlled furnace atmosphere, so surface does not oxidize, remaining bright. |
| Bright Annealing 2 | (english) The process of annealing in a protective atmosphere so as to prevent discoloration of the bright surface desired. |
| 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. |
| Bruise | (english) A mark transferred to the strip surface from a defective process roll. Similar to dent or punchmark. |
| 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. |
| Aerobic process | (Environmental Engineering) A process which requires molecular oxygen. |
| Anaerobic process | (Environmental Engineering) A process which only occurs in the absence of molecular oxygen. |
| Anoxic process | (Environmental Engineering) A process which occurs only at very low levels of molecular oxygen or in the absence of molecular oxygen. |
