Square tube performance


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


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.

Impact toughness

The load acting on the machine at a large speed is called the impact load, and the metal is under the impact load.

The ability to resist damage is called impact toughness.


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 a basic strength indicator.

Hardness is a measure of the hardness of a metal material. At present, the hardness method is commonly used in the production of hardness method. It is pressed into the surface of the metal material to be tested under a certain load by a certain geometry of the indenter, and the hardness value is determined according to the degree of being pressed.

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