| Braze Welding | (english) A family of welding procedures where metals are joined by filler metal that has a melting temperature below the solidus of the parent metal, but above 840 (450 C). |
| Brazing | (english) Joining metals by fusion of nonferrous alloys that have melting points above 800 F (425C), but lower than those of the metals being joined. May be accomplished by a torch. Filler metal is ordinarily in rod form in torch brazing; whereas in furnace and dip brazing the work material is first assembled and the filler metal may then be applied as wire, washers, clips, bands, or may be bonded, as in brazing sheet. |
| Break Test (for tempered steel) | (english) A method of testing hardened and tempered high carbon spring steel strip wherein the specimen is held and bent across the grain in a vice-like calibrated testing machine. Pressure is applied until the metal fractures at which point a reading is taken and compared with a standard chart of brake limitations for various thickness ranges. |
| Breakage | (english) Cracks or separation of the steel. |
| Breaker | (english) Uncoiler rolls through which the strip passes; composed of a mandrel and leveling rolls which unwind the strip prior to processing through the Pickler. Breaker rolls assist in breaking up the Hot Mill surface scale. |
| BREATHER | (english) A device which permits air to move in and out of a container or component to maintain atmospheric pressure. |
| Bridle | (english) A set of rolls used to maintain tension on the strip as it goes through the line. |
| Bridle Rolls | (english) A series of neoprene or steel rolls. |
| Bridle Snubber | (english) The roll above the bridle rolls used to thread the strip. Also is used to steer the strip through the bridle. |
| Bridling | (english) The cold working of dead soft annealed strip metal immediately prior to a forming, bending, or drawing operation. A process designed to prevent the formulation of Luder's lines. Caution-Bridled metal should be used promptly and not permitted to (of itself) return to its pre-bridled condition. |
