Backwardation |
(english) Market condition where the spot, or current price for a metal is higher than the three-month delivery price. This usually indicates immediate demand is perceived to be stronger than long-term demand. Not considered to be a "normal" market state (See Contango). |
Bainite |
(english) A eutectoid transformation product of ferrite and a fine dispersion of carbide, generally formed at temperatures below 840 to 930 F (450 to 500 C): upper bainite is an aggregate containing parallel lath-shape units of ferrite, produces the so-called feathery appearance in optical microscopy, and is formed at temperatures above about 660 F (350 C); lower bainite consists of individual plate-shape units and is formed at temperatures below about 660 F (350 C). Also, a slender, needle-like (acicular) microstructure appearing in spring steel strip characterized by toughness and greater ductility than tempered Martensite. Bainite is a decomposition product of Austenite best developed at interrupted holding temperatures below those forming fine pearlite and above those giving Martensite. |
Bake Hardenable Steel |
(english) A cold-rolled, low-carbon sheet steel used for automotive body panel applications. Because of the steel’s special processing, it has good stamping and strength characteristics and after paint is baked on, improved dent resistance. |
Baked Core |
(english) A core which has been heated through sufficient time and temperature to produce the desired physical properties attainable from its oxidizing or thermal-setting binders. |
Balanced Steel |
(english) Steels in which the deoxidisation is controlled to produce an intermediate structure between a rimmed and killed steel, Sometimes referred to as semi-killed steels, they possess uniform properties throughout the ingot and amongst their applications are boiler plate and structural sections. |
Ball Burnishing |
(english) A method of obtaining a high luster on small parts by rotating them in a wooden-lined barrel with water, burnishing soap, and stainless steel shot. |
BALL VALVE |
(english) A valve that may be used to divert the flow of fluid in a passage. Most normally configured in a two-way pattern that is either open or closed. |
Baller Stick |
(english) Octagon-shaped wooden stick approximately 5' long. This stick is used in the baller area, to change burr mashers, to start a coil with a large ID, etc. |
Bamboo Grain Structure |
(english) A structure in wire or sheet in which the boundaries of the grains tend to be aligned normal to the long axis and to extend completely through the thickness. |
Band Saw Steel (Wood) |
(english) A hardened tempered bright polished high carbon cold rolled spring steel strip produced especially for use in the manufacture of band saws for sawing wood, non ferrous metals, and plastics. Usually carries some nickel and with a Rockwell value of approximately C40/45. |
