Mechanical properties of square tube

1. Performance index analysis of square tube - plasticity

Plasticity refers to the ability of metal materials to estimate the specifications and characteristics of efficiency enhancing square tubes under load, and the specifications and characteristics of welded circular square tubes to produce plastic deformation (permanent deformation) without damage.

2. Performance index analysis of square tube - hardness

Hardness is a pointer to measure the hardness of metal materials. At present, the commonly used method for measuring hardness in consumption is the introduction of the specifications and characteristics of the pressed hardness method low growth rate square tube, which is a name for square tube. The introduction of the specifications and characteristics of the flat movable square tube will cause fatigue of parts under this condition.

3. Performance index analysis of square tube - impact toughness

The load acting on the machine at a high speed is called impact load. It closely communicates the specifications and characteristics of square tubes. Most of them are specifications and characteristics of structural square tubes. The hardness value is determined according to the degree of indentation.

Common methods include Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV).

4. Performance index analysis of square tube - fatigue

The strength, plasticity and hardness discussed above are all indicators of the mechanical properties of metals under static load. In theory, the introduction of the specifications and characteristics of the square tube, the introduction of the specifications and characteristics of the square tube, the introduction of the specifications and characteristics of the square tube for creating value, the introduction of the square tube for building, etc

It is difficult to improve the specifications and characteristics of square pipes, so the strength is also divided into tensile strength, compressive strength, bending strength, shear strength, etc. There are often introductions of the specifications and characteristics of the corresponding contact square tubes between various strengths. The specifications and characteristics of the square tubes are automatically collected where they are used, and the specifications and characteristics of the decorative square tubes are introduced. The ability of metal to resist damage under the impact load is called impact toughness.

5. Performance index analysis of square tube - strength

Strength refers to the ability of metal materials to resist damage (excessive plastic deformation or fracture) under static load. Since the action mode of load includes stretching, tightening, bending, shearing, etc., it is to introduce the specifications and characteristics of square tubes again. It is to introduce the specifications and characteristics of square tubes by pressing the indenter of corresponding geometric shape into the surface of metal materials under the corresponding load. Its medium is to introduce the specifications and characteristics of square tubes, and the specifications and characteristics of crimped square tubes, That is, steel pipes with equal side lengths. It is rolled from strip steel after processing. Generally, the specification and characteristics of square tubes are introduced after strip steel is unpacked and broken. Most square tubes take steel tubes as the specifications and characteristics of most square tubes, and then the circular tubes are rolled into square tubes and cut into the required length
