Angle iron, also known as angle steel, its mechanical properties mainly include the following aspects:
1. strength
      Angle iron has high tensile strength and compressive strength. The tensile strength enables it to withstand tensile force without fracture, while the compressive strength ensures its good stability under pressure without deformation or damage. This enables the angle iron to be used as a supporting and connecting part in the fields of building structure, machinery manufacturing and so on, and to bear large loads.
      The strength of angle iron varies with different models and materials. Generally speaking, with the increase of the size of the angle iron and the strength grade of the material, its tensile and compressive strength will increase accordingly. For example, the strength of angle iron made of Q345 is higher than that of Q235.
2. toughness
      Angle iron has certain toughness and can absorb energy when subjected to impact load to avoid sudden fracture. Toughness enables angle iron to work reliably in some occasions that may suffer vibration and impact, such as bridge structure, lifting equipment, etc.
      The excellent angle iron has good toughness at room temperature, but with the decrease of temperature, its toughness may decline and become brittle fracture easily. Therefore, when using angle iron in low temperature environment, it is necessary to select the appropriate material and model to ensure that its toughness meets the requirements.
3. hardness
      Angle iron has relatively high hardness and good wear resistance. This feature enables it to be applied in some parts vulnerable to friction and wear, such as the support of mechanical parts, guide rails and so on.
      The hardness of angle iron is related to its material and heat treatment state. The hardness and wear resistance of angle iron can be further improved by appropriate heat treatment processes, such as quenching and tempering, to meet the requirements of different working conditions.
4. fatigue performance
      When the angle iron is subjected to cyclic load, fatigue will occur. Fatigue performance is an index to measure the failure resistance of angle iron under long-term cyclic loading.
      The fatigue performance of angle iron is affected by many factors, such as the purity of material, surface quality, stress concentration and so on. When designing and using angle iron, it is necessary to consider its fatigue performance and reasonably select materials and structural forms to ensure that the angle iron will not fail due to fatigue within its service life.
