  Technology for heating processing
  • General steel heat treatment includes the following techniques:
    Quenching

    Steel is heated to a temperature higher than its transformation point to form austenite; then the steel is quickly cooled to form martensite. This process increases the hardness and strength of the steel without changing its shape, but the steel becomes more brittle.

    
    
    

    Tempering

    Heating the steel again after quenching adds elasticity and toughness, transforming the steel to a structure with high resistance to wear. However, the hardness is slightly reduced when compared with the state after quenching..
    Annealing

    This process is used to improve the structure and soften the steel since semi-hard steel, hard steel and alloy steel are difficult to cut due to their hardness.

    
    • 
      • Normalizing
        This process is used to make the structure finer, uniformize carbides and remove residual stresses, thus making the steel easier to cut. Since hardenability also improves, normalizing is sometimes used as a pre-process before quenching.

     How do you test the composition of a metal?怎样测试金属的成分?

    The two most common methods used to determine the chemical composition of an alloy (or any metal) are

    X-ray fluorescence spectroscopy (XRF) and optical emission spectroscopy       (OES). XRF is non-destructive,

    however, OES is more sensitive than XRF to lighter elements.
