Brinell Hardness Test

แปลว่า(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.

Rotation:

แปลว่า(english) Motion of an object where the path of every point is a circle or circular arc. A rotation is defined by a point and vector which determine the axis of rotation. The direction of the vector is the direction of the axis and the magnitude of the vector is the angle of rotation.

Backwardation

แปลว่า(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).

ACTUATOR

แปลว่า(english) A device for converting hydraulic energy into mechanical energy, i.e., a motor or cylinder.

Blanking

แปลว่า(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.

Beading

แปลว่า(english) Raising a ridge on sheet metal

Stability:

แปลว่า(english) Stability is best defined as the opposite of instability, which is the occurrence of large structural deformations which are not the result of material failure.

Brite

แปลว่า(english) 1) Regular galvanize coating (not minimized spangle or JP). 2) Rolls that have no grit; smooth finish on surface of steel.

Back End

แปลว่า(english) 1) Usually refers to the entry end of process lines. 2) The outside lap 2) of the produced coil, or the inside lap of the consumed coil.

ABSOLUTE PRESSURE

แปลว่า(english) The indicated value of the weight of the earth's atmosphere. At sea level, this value is approximately 14.65 psi (pounds per square inch).

Black Iron

แปลว่า(english) Uncoated steel product.

Inertia:

แปลว่า(english) The tendency of an object at rest to remain at rest, and of an object in motion to remain in motion.
