How to calculate the size or weight of structural steel and miscellaneous metals? The term steel specification is very often closely related to and used interchangeably with standards, although their meaning is not really identical. The most widely used standard steel specifications in the United States are those published by ASTM. These steel specifications represent a consensus drawn from producers, fabricators, and users of steel mill products. The Key to metals database brings global metal specifications and properties together into one integrated and searchable database. The section size, finishing temperature, and cooling rate during the rolling process influence the final mechanical properties of any steel in the As-Rolled condition. The amount of size reduction in cold drawing will affect the mechanical properties of Cold Drawn Bars. Turned and Polished as well as Turned, Ground, and Polished Bars have approximately the same mechanical properties as the Hot-Rolled Bars from which they were produced. Beams experience tensile, sheer, and compressive stresses internally due to the loads applied to them. Generally, in cinder gravity loads there is a slight reduction in the original length of the beam.
