| Boss | (english) A projection or an enlarged section of a casting through which a hole may be machine. |
| Box Annealing | (english) Annealing a metal or alloy in a sealed container under conditions that minimize oxidation. In box annealing a ferrous alloy, the charge is usually heated slowly to a temperature below the transformation range, but sometimes above or within it, and is then cooled slowly; this process is also called close annealing or pot annealing. |
| Box Annealing 2 | (english) A process of annealing a ferrous alloy in a closed metal container, with or without packing materials, in order to minimize the effects of oxidation. The charge is normally heated slowly to a temperature below the transformation range, but occasionally above or within it, and then is slowly cooled. |
| Brake Press Bending | (english) An operation which produces various degree bends when fabricating parts from steel. |
| Brass | (english) An alloy that is 70% copper,30% zinc. One of the most widely used of the copper-zinc alloys; malleable and ductile; excellent cold-working but poor hot-working and machining properties; excellent for soft-soldering; good for silver alloy brazing or oxyacetylene welding, but fair for resistance or carbon-arc welding. Used for drawn cartridges, tubes, eyelets machine items and snap fasteners. |
| 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). |
| 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. |
| 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. |
| 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. |
