Rolling or machined steel into a square section

The density of steel is 7.851g/cm3

Theoretical weight calculation of steel

The unit of measurement for calculating the theoretical weight of steel is kilogram (kg).The basic formula is as follows:

W (weight, kg) =F(sectional area mm2)×L(length, m)×ρ(density, g/cm3)×1/1000

Square steel can be divided into hot rolled and cold rolled two;Hot-rolled square steel side length 5-250mm, cold-drawn square steel side length 3-100mm.

 

Cold drawn square steel editing

Cold drawn square steel refers to cold drawn steel forged in square shape

Cold drawn steel is under normal temperature conditions, in order to exceed the original strength of the yield point of the tensile stress, forced tensile reinforcement, so that the plastic deformation of the steel bar to achieve the purpose of improving the strength of the yield point of steel and saving steel.

Cold drawn steel is the use of cold extrusion technology, through the precise mold, to pull out all kinds of high precision, smooth surface of round steel, square steel, flat steel, hexagonal steel and other special-shaped steel.

Reinforcing cold pull concept: in order to save steel, improve the yield strength of steel for the purpose, in order to exceed the yield strength and less than the ultimate strength of the tensile stress tensile reinforcement, so that its plastic deformation of the practice called cold pull of steel.
