| 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 Basic Wire | (english) Bright steel wire, slightly softer than Bright Bessemer Wire. Used for round head wood screws, bolts and rivets, electric welded chain, etc. |
| Bright Bessemer Wire | (english) Stiff bright wire of hard temper. Normally wire is drawn down to size without annealing. |
| Bright Dip | (english) An acid solution into which pieces are dipped in order to obtain a clean, bright surface. |
| 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. |
| Brine | (english) A saltwater solution for quenching or cooling when heat treating steel. |
| Brinell Hardness | (english) The hardness of a metal or part, as represented by the number obtained from the ratio between the load applied on the spherical area of the impression made by a steel ball forced into the surface of the material tested. |
| Brinell Hardness Number | (english) The value of hardness of a metal on an arbitrary scale representing kg/mm2, determined by measuring the diameter of the impression made by a ball of given diameter applied under a known load. Values are expressed in Brinell Hardness Numbers, BHN |
