Square Tube Steel Features Use Square Tube Steel Spec Sheet

Square pipe is a name for square pipe, that is, equal length of steel pipe. It is a strip processed by a process coil. Square pipe steel, it is a kind of square body pipe, a variety of materials can be formed into a square pipe body, it is medium, most of the square pipe to the pipe as the majority, after unpacking, flat, curled, welded to form a round tube It is then rolled into a square tube and then cut to the required length. The uses of square pipes include construction, machinery manufacturing, steel construction and other projects. Here we will introduce the characteristics of the use of square tube steel and square tube steel specifications table .

Square tube steel features use

1, square tube product description

Square tube is a kind of hollow square cross-section lightweight thin-walled steel tube, also known as steel refrigerated bending profile. It is based on Q235 hot-rolled or cold-rolled strip or coil plate as the parent metal after cold bending and forming high-frequency welding and then made of square section shape size of steel. Hot-rolled extra-thick-walled square tubes are thickened and thickened except for corner thickness and edge flatness, which have reached or even exceeded the level of resistance-weld cold-formed square tubes. It has good mechanical properties, good weldability, cold and hot workability and corrosion resistance, and good low temperature toughness.

2, the use of square tube

The uses of square pipes include construction, machinery manufacturing, iron and steel construction and other projects, shipbuilding, solar power support, steel structure engineering, power engineering, power plants, agriculture and chemical machinery, glass curtain walls, car chassis, airports, boiler construction, highway railings, Housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, hoisting and transporting machinery, and other higher load welded structural components.

Square tube steel performance

1, plasticity

Plasticity refers to the ability of a metal material to undergo plastic deformation (permanent deformation) without breaking under load.

2, hardness

Hardness is a measure of the degree of hardness and hardness of metallic materials. At present, the most commonly used method for measuring hardness in production is the press-in hardness method. It uses a certain geometric shape of the indenter to press the surface of the tested metal material under a certain load, and the hardness value is determined according to the degree of press-in.

The commonly used methods are Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV).

3, fatigue

The strength, plasticity, and hardness discussed above are all indicators of the mechanical properties of the metal under static loading. In fact, many machine parts work under cyclic loading, under which conditions the parts will fatigue.

4, impact toughness

The load acting on the machine part at a great speed is called impact load. The ability of the metal to resist damage under the impact load is called impact toughness.

5, strength

Strength refers to the resistance of a metallic material to damage (excessive plastic deformation or fracture) under static loading. Because the load has the form of tension, compression, bending, shearing, etc., the strength is also divided into tensile strength, compressive strength, bending strength, shear strength and so on. There is often a certain connection between various strengths, and the tensile strength is generally used as the most basic strength indicator in use.

Square tube calculation formula

Square tube weight calculation formula: 4* wall thickness*(side length-wall thickness)*0.00785

Round tube weight calculation formula: {(perimeter length 3.14)-wall thickness} * wall thickness * 0.02466

Remarks: The above unit is kg/m, where the unit of wall thickness and side length is mm, ie mm.

Conclusion: The relevant information on the use of square steel products and the specification of square tube steel specifications was introduced here.
