1. Performance index analysis of square tube - plasticity
Plasticity refers to the ability of metal materials to undergo plastic deformation (permanent deformation) without destruction under load.
2. Performance index analysis of square tubes - Hardness
Hardness is a measure of the softness and hardness of metal materials. At present, the most commonly used method for measuring hardness in production is the pressing hardness method, which is used to press the surface of the tested metal material with a certain geometric shape under a certain load, and determine its hardness value according to the degree of pressing.
The commonly used methods include Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV).
3. Performance index analysis of square tube - fatigue
The strength, plasticity, and hardness discussed above are all indicators of the mechanical properties of a metal under static loading. In fact, many machine parts are operated under cyclic loads, and fatigue can occur under these conditions.
4. Performance index analysis of square tube - impact toughness
The load on the parts at a great speed is called impact load, and the ability of the metal to resist damage under impact load is called impact toughness.

Strength refers to the resistance of a metal material to failure (excessive plastic deformation or fracture) under static charge. Due to the mode of action of the load has tensile, compression, bending, shear and other forms, so the strength is also divided into tensile strength, compressive strength, flexural strength, shear strength and so on. There is often a certain relationship between various strengths, and the use of tensile strength is generally more as the most basic strength pointer.
