Butcher Saw Steel |
(english) A hardened, tempered, and polished high carbon spring steel strip material (carbon content is generally higher than that of a material used for wood band saw applications) with a Rockwell value of roughly C47/49. |
Butt Welding |
(english) Joining two edges or ends by placing one against the other and welding them. |
Butt-Weld Pipe |
(english) The standard steel pipe used in plumbing. Heated skelp is passed continuously through welding rolls, which form the tube and squeeze the hot edges together to make a solid weld. |
By Coil |
(english) Selling term which refers to product sold in the form of a coil vs. cut plate. "Bi Coil" is also used in production to refer to coils vs. cut plate |
Z-Mill |
(english) The full name for z-mill is Sendzimir mill. A Z-mill operates with a very small diameter work roll, normally about 2 inches, backed up by a number of rolls in a pyramid-shaped stack. This roll set up allows you to exert extremely high forces through the work roll and yet keep the work roll from extreme flexing. The take-up roll on the Z-Mill also exerts a tension on the coil as it comes through the mill. The combination of high pressure and tension makes the mill capable of rolling material thin and flat. |
Zinc |
(english) Chemical Symbol Zn. Element No. 30 of the periodic system; atomic weight 65.38. Blue-white metal; when pure, malleable and ductile even at ordinary temperatures; melting point 787 (degrees) F.; boiling point 1665 (degrees) F., specific gravity 7.14. Can be electrodeposited; it is extensively used as a coating for steel and sheet zinc finds many outlets, such as dry batteries, etc. Zinc-base alloys are of great importance in die casting. Its most important alloy is brass. |
Zirconia |
(english) ZrO2 an acid refractory up to 2500 B0C (4532 B0F) having good thermal shock resistance and low electrical resistively. |
Zirconium |
(english) Silvery-white, metallic element, mp 1860 B0C (3380 B0F), a powerful deoxidizer when added to molten steel. |
Acceleration: |
(english) A vector quantity equal to the rate that velocity changes with time. |
Axial force: |
(english) A system of internal forces whose resultant is a force acting along the longitudinal axis of a structural member or assembly. |
