    1. Performance index analysis of  ASTM A36 carbon steel welded square pipe plasticity
    Plasticity refers to the ability of metal materials to produce plastic deformation (permanent deformation) without damage under load.
    2. Performance index analysis of square tube - hardness
    Hardness is a pointer to measure the hardness of metal materials. At present, the most commonly used hardness measurement method in production is the indentation hardness method, which uses an indenter with a certain geometric shape to press into the surface of the metal material to be tested under a certain load, and determines its hardness value according to the degree of indentation.
    Common 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 metals under static load. In fact, many machine parts work under cyclic load, in which case fatigue will occur.
    4. Performance index analysis of square tube - impact toughness
    The load acting on the machine at a high speed is called impact load, and the ability of metal to resist damage under 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 modes of load include tension, compression, bending, shear, etc., the strength is also divided into tensile strength, compressive strength, bending strength, shear strength, etc. There is often a certain relationship between various strengths, and the tensile strength is generally used as the most basic strength indicator.

    PRODUCT ADVANTAGES

    01  Performance index analysis of square tube - good plasticity

    Plasticity refers to the ability of metal materials to produce plastic deformation (permanent deformation) without damage under load.

    • 02  Performance index analysis of square tube - high hardness

    Hardness is a pointer to measure the hardness of metal materials. At present, the most commonly used hardness measurement method in production is the indentation hardness method, which uses an indenter with a certain geometric shape to press into the surface of the metal material to be tested under a certain load, and determines its hardness value according to the degree of indentation.

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