| Bell Mouth | (english) The flaring or tapering of a machined hole, usually made at the entrance end because of misalignment or spring of the cutting tool. |
| Bend Radius | (english) The inside radius of a bent section, |
| Bend Test | (english) Various tests which is used to ascertain the toughness and ductility of a metal product, in which the material is bent around its axis and/ or around an outside radius. A complete test might specify such a bend to be both with and against the direction of grain. For testing, samples should be edge filed to remove burrs and any edgewise cracks resulting from slitting or shearing. If a vice is to be employed, then you must line the jaws with some soft metal, to permit a flow of the metal in the piece being tested. |
| Bending | (english) A preliminary forging operation to give the piece approximately the correct shape for subsequent forming. |
| Bending Angle | (english) A 'V-shaped' piece of angle iron attached to the rear of the coil car in the Strip Steel, which is used to help the operator put bends into the front end of a coil. |
| Bending Strength | (english) Upper limit of normal stress of a beam at which fracture or excessive plastic deformation occurs. |
| Bevel | (english) Angle formed between the prepared edge of the end of tube and a plane perpendicular to the surface. Standard pipe bevel is 30 degrees. |
| Big Winch | (english) The tool used to spot (or position) the rail cars for unloading. It is located on the north end of the unloading area. |
| Black Oil Tempered Spring Steel Strip (Scaleless Blue) | (english) A flat cold rolled usually .70/.80 medium high carbon steel strip, blue-black in color, which has been quenched in oil and drawn to desired hardness. While it looks and acts much like blue tempered spring steel and carries a Rockwell hardness of C44/47, it has not been polished and is lower in carbon content. Used for less exacting requirements than clock spring steel, such as snaps, lock springs, hold down springs, trap springs, etc. It will take a more severe bend before fracture than will clock spring, but it does not have the same degree of spring-back. |
| Blanking | (english) An early step in preparing flat-rolled steel for use by an end user. A blank is a section of sheet that has the same outer dimensions as a specified part (such as a car door or hood) but that has not yet been stamped. Steel processors may offer blanking for their customers to reduce their labor and transportation costs; excess steel can be trimmed prior to shipment. |
