| 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. |
| 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 Test | (english) A common standard method of measuring the hardness of materials. The smooth surface of the metal is subjected to indentation by a hardened steel ball under pressure. The diameter of the indentation, in the material surface, is then measured by a microscope and the hardness value is read from a chart or determined by a prescribed formula. |
| Brinell Hardness Testing | (english) Method of determining the hardness of materials; involves impressing a hardened ball of specified diameter into the material surface at a known pressure (10-mm ball, 500-kg load for aluminum alloys). The Brinell hardness number results from calculations involving the load and the spherical area of the ball impression. Direct-reading testing are generally used for routine inspection of forgings, and as a heat treat control function. |
| Brite | (english) 1) Regular galvanize coating (not minimized spangle or JP). 2) Rolls that have no grit; smooth finish on surface of steel. |
| Broach | (english) A long, tapered cutting tool with serrations which,when forced through a hole or across a surface, cuts a desired shape or size. |
| Broaching | (english) Smoothing machined holes or outside surfaces of castings by drawing pushing on or more broaches (special cutting tools) through the roughed out hole. |
| Bruise | (english) A mark transferred to the strip surface from a defective process roll. Similar to dent or punchmark. |
