steel square pipe

Steel square pipe is called square pipe, also called square pipe. It is a kind of square pipe, which is a steel pipe with equal sides. It is a strip of steel that has been processed and rolled.It is a square tube type. A variety of materials can form a square tube. It is medium, what is used, and where it is used. Most square tubes are made of steel tubes, mostly structural square tubes, decorative squares. Tube, building square tube, etc.

The square tube is seamless and welded, and the seamless square tube is formed by extruding a seamless tube. Square steel pipe, thick-walled square steel pipe, large diameter square steel pipe, seamless square steel pipe, low alloy square steel pipe, 135*135*10 square steel pipe, square steel pipe for tower crane, Q345B low alloy square steel pipe, 20# seamless square steel pipe.

1.Performance index analysis of square tube – plasticity

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

2.Performance index analysis of square tube – fatigue

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

3.Performance index analysis of square tube – impact toughness

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

4.Performance index analysis of square tube – hardness

Hardness is a measure of the hardness of a metal material. At present, the most commonly used method for measuring hardness in production is the indentation hardness method, which presses the surface of the metal material to be tested under a certain load with a certain geometry of the indenter, and determines the hardness value according to the degree of being pressed.

5.Square tube performance index analysis – strength

Square steel pipe, thick-walled square steel pipe, large diameter square steel pipe, seamless square steel pipe, low alloy square steel pipe, 135*135*10 square steel pipe, square steel pipe for tower crane, Q345B low alloy square steel pipe, 20# seamless square steel pipe.

Strength refers to the property of a metal material against damage (excessive plastic deformation or fracture) under static load. Since the action mode of the load is tensile, compression, bending, shearing, etc., the strength is also divided into tensile strength, compressive strength, bending strength, shear strength and the like. There is often a certain relationship between various strengths, and tensile strength is generally used as the most basic strength indicator.
